Version 3.0 Release Notes ======================================== Version History/Revision History ------------------------------------------------------- This is the Release Notes for \ |software_prod_name|\ version 3.0, released April 25th 2025. .. note:: This document refers to \ |software_prod_name|\ as the "Product". Release Highlights --------------------------- Edge Orchestrator is the primary product within the Edge Manageability Framework. Edge Orchestrator enables you to securely onboard and provision remote edge devices to a central management plane, orchestrate Kubernetes\* clusters and applications across distributed edge, at scale. Edge Node software provides the profiles of infrastructure software configurations that get provisioned onto an onboarded node. Key Highlights of the release include, but not limited to: * Zero-touch, secure, onboarding, and provisioning of remote edge nodes on management plane, that makes it easy to manage lifecycle of distributed edge infrastructure – from maintenance to upgrades. * Onboarding remote devices either via HTTPs boot or USB-assisted boot to provide flexibility to onboard for a range of existing as well as new devices. * Built-in security capabilities such secure onboarding, full disk encryption, secure communications, and so on to help with zero trust security needs at the edge. * Ability to scale easily to thousands of edge nodes in distributed locations, enabling IT teams to have better visibility into the distributed edge infrastructure, from a single dashboard. * Multitenancy support for multiple projects and organizations with centralized identity and access management for enhanced project and organization level isolation. * Ability to orchestrate heterogenous Kubernetes clusters and deploy and manage applications via an application orchestrator through policies defined by the user. * Advanced application orchestration capability to utilize application interconnects that can help build a fully automated pipeline such as those required for MLOps. * Pre-built Edge Node Software profiles to provision edge nodes with Ubuntu\* OS as well as Edge Microvisor Toolkit immutable operating system, enabling deployment of modern AI workloads in containers or virtual machines. * Intel-GPU support built in, so that applications can easily take advantage of the computing power from integrated and discrete Intel® Arc™ graphics * An intuitive user interface to with a dashboard to have a simplified, central view into all the nodes, clusters, and applications running across the distributed edge infrastructure. * Deep observability and telemetry built in, along with pre-built Grafana\* dashboards to look at the metrics for resource utilization, and so on, enabling teams to improve operational efficiency. * Support for Intel Atom® platform, Intel® Core™ processor, Intel® Core™ Ultra processor, Intel® Xeon® platform, and Intel® Ethernet Network Adapters. * Support for Intel® Arc™ and Intel® integrated graphics. * Ability to deploy Edge orchestrator both on cloud and on premises infrastructure with easy to use installer scripts. For a detailed list of features, see the following release notes. The software comprises of the following key components: * Application Orchestrator and Catalog Services * Cluster Orchestrator * Edge Infrastructure Manager * Comprehensive User Interface * Observability, Telemetry, Monitoring, and Alerting * Edge Node Software Agents * Foundational Platform Services Detailed Features in This Release -------------------------------------------- Version 3.0 provides the following additional features and enhancements on top of previous closed source versions. Open Sourcing of the codebase * Open Sourcing of the codebase * Use Apache\* software version 2.0 license. * All repositories can be cloned and built as an artifact (binary file, rpm, or Docker\* container). * All components have minor versions. * Simplified the total number of repositories. * Each repository has a README.md file. * Introduce a complete and new Developer Documentation. * Edge Orchestrator overview. * Contributing guide. * Architecture guide for all components. * Tutorials and troubleshooting. * Application development flow. * Edge node cluster management via Cluster API (CAPI) * Cluster providers are based on the open cluster API standard, for the existing device and infrastructure, Kubernetes\* clusters in Rancher\* Setup provisioning and other flavors like the vanilla Kubernetes setup. * Support cluster templates and profiles based on CAPI, to configure the cluster. * Continuous support for multitenancy, edge-cluster access, and integration with other Edge Orchestrator services. * Support for single-node clusters. * Edge node zero-touch onboarding and provisioning with pre-registration * Pre-register a node with OS, security (secure boot and full-disk encryption), metadata, and SSH key configuration. * Allow the user to avoid, by default, several manual BIOS configuration ahead of on-boarding and provisioning a node, such as secure boot and full-disk encryption); moving from an opt-out model to an opt-in, optional configuration. * Day0 and Day1 configuration for edge nodes and OS configuration is done via industry standard `cloud-init `_. Cloud-init performs static configuration files and perform OS configurations that are self-contained and do not require network connectivity * Remote edge-node access using SSH public key-based authentication. * Increased and enhanced infrastructure edge-node status and user-interface pages * All hosts are reported in a single page; categorized using `Provisioned`, `Onboarded`, `Registered`, and `All`, matching the lifecycle phase. * Report of the different edge-node agents and component status. * Visibility to additional elements, such as workload. * Drop-down menu for each host with inline details. * Visual cue of the ability to upgrade the node. * List of installed packages for immutable images. * Enhanced Lenovo\* system integration * Support for LOC-A version 3.3.x. * OS provisioning can be triggered using |software_prod_name|\. * Support for `Viana\* platform `_ edge-init v1.0 application. * Support for Intel® applications * Newest version of pallet defect detection. * Image-based video search. * ChatQnA. * Support for common Helm\* applications * A sample set of Bitnami\* applications was selected to validate Edge Orchestrator's compatibility with common Helm charts and applications. These examples were chosen to represent varying levels of complexity, ranging from simple single-pod applications to multi-pod applications that incorporate databases, ingress controllers, and persistent volumes. The selected applications include: * Gitea\* platform, a self-hosted Git\* service * JupyterHub\* server, a web-based interactive computing platform with multiple services * MongoDB\* platform, a NoSQL database * NGINX\* web server * WordPress\* system, a blogging platform that includes an internal Postgres\* database * Enhanced Edge Orchestration deployment and operation * Reduced number of manual steps. * One click installation in less than 30 minutes. * Initial Support for Trusted Compute * Provision a Trusted Compute-capable edge node. * Create a cluster to have Trusted Compute-capable edge node. * Remove the Trusted Compute-capable edge node in a cluster. * Add Trusted Workloads into the Application Catalog. * Attestation Failure on the Trusted Compute-capable edge node. Refer to the user guide for detailed documentation of these features. All of the before mentioned enhancements are present in both AWS\* cloud-based and on-premises Product deployments. The following are further descriptions of some of the enumerated enhancements. Upgrades from Previous Releases ---------------------------------- You would not be able to upgrade |software_prod_name| to release 3.0 from any previous releases, because of the changes and features outlined in the sections above, especially the move to open source repository and the deprecation of Rancher\* platform. Any installation must be a fresh install; if you had a previous installation Intel recommends to uninstall by following the instructions in the guide and then proceeding with a fresh install of release 3.0. Known Issues ---------------------------------- The following are known issues in the release. While several know issues and limitations have been addressed during the 3.0 release cycle, some have been still carried over from past releases. Provisioning ^^^^^^^^^^^^^ * Provisioning is halted in case of Secure flag and Secure Boot BIOS setting mismatch; the BIOS setting is used. There are different cases: * Case 1: Secure boot disabled in BIOS and Security Feature disabled in UI - the edge node will boot seamlessly and a messages "Verifying Secure Boot settings match" will be displayed on the UI. * Case 2: Secure boot disabled in BIOS and Security Feature enabled in UI - the edge node will not boot and a message "Verifying Secure Boot settings match failed" will be displayed on the UI. * The OS is curated (configured) only once during edge node provisioning, thus any update to the OS profile after that initial curation is not applied dynamically. * If Out-of-Tree (OOT) driver installation with secure boot option enabled fails because of secure boot password request on the edge node hardware, reboot the edge node hardware. * If the edge node reboots during the full-disk encryption (FDE) stage, the edge node will try and boot to disk but will then fail because of partial encryption. The workaround is to delete the host and then re-provision. * If there are network issues during initial provisioning of the edge node, see :doc:`/user_guide/troubleshooting/en_recover`. * If an edge node fails to boot properly during initial provisioning, see :doc:`/user_guide/troubleshooting/hard_disk_boot`. * An edge node's OS might intermittently enter maintenance mode during provisioning after uOS workflow completion. Reboot the edge node, possibly more than once, to get out of this state. * Occasionally during provisioning, a bad gateway (502) error can happen, thus failing the workflow. Delete the edge node from the Product (see :doc:`/user_guide/set_up_edge_infra/delete_host`) and then reboot it to restart the provisioning. * On rare occasions, the Local Volume Manager (LVM) creation of edge nodes with FDE disabled, fails because it requires input through the keyboard. Reboot the edge node to proceed. * In certain situations during provisioning, the edge node might experience a boot loop where it tries to complete the provisioning process. Intel recommends powering off the edge node, deleting it (see :doc:`/user_guide/set_up_edge_infra/delete_host`), and then re-provisioning it. * Occasionally, logging and metrics are not enabled during deployment. This might be because the Docker\* software pull limit is reached. First, delete the edge node (see :doc:`/user_guide/set_up_edge_infra/delete_host`) and then re-provision it with a different IP address. * The default Elastic IP (EIP) Service Quota must be increased before installing the Product on the cloud, to allow for 13 EIPs to be provisioned for the Product on Cloud. * If several edge nodes are provisioned at the same time from a non-premium Docker\* account, there is a limit of 100 pulls per IP over a four-hour window. In this case, upgrade to the premium account or wait to provision more edge nodes. * When a user tries to re-provision without FDE, a node that was previously provisioned with FDE will not succeed due to un-successful persistent volume creation on disk. The workaround is to manually issue the `dd` command: `dd if=/dev/zero of="/dev/disk_name" bs=32m count=100` for the correct disk `disk_name` before re-provisioning without FDE. * The AAEON UP Squared Pro 7000\* platform provisioning might fail - `Provisioning Failed: 2/15: Erasing data from all non-removable disks failed`. To proceed, the BIOS configuration for the eMMC controller must be disabled in `Main > CRB Setup > CRB Chipset > PCH-IO Configuration > SCS Configuration > eMMC Controller > Disabled`. * Provisioning a node with Ubuntu-ext OS profile through an on-premises Edge Orchestrator in an OT network will cause a failure due to squid proxy unauthorizing the request with 403. There is no workaround; utilize the base Ubuntu profile and install any additional drivers through Day 2 updates. * Logs and metrics are currently not available for Edge Nodes provisioned via LOC-A. Hosts and Infrastructure ^^^^^^^^^^^^^^^^^^^^^^^^^ * On the host pages, if a host ends its `Under Maintenance` period when a user is viewing the page, the maintenance status for the host in the table will not be updated until the user switches pages or refreshes the page. * For Intel® Core™ processor platforms with E-cores and P-cores, the CPU thread count may be reported incorrectly, where single-threaded E-cores are counted as having two threads. The CPU model and total core count (sum of both P and E) are correct. * When scheduling updates, select the start time of the OS updates after the current time by at least 10 minutes; otherwise, the update may not start. * It is possible that a node is reported with host status `Provisioning In Progress: 26/26: Rebooting` in the host views of the User Interface. Confirm the actual status of the host by clicking on it and checking the detailed `Status` panel at the bottom: if the `Host Status` is `Running`, then the node is in the correct state and can be used for cluster and application installation. You will see that the `Provisioning Status` is equal to what is shown in the list view. The issue happens because the list view gives precedence to the `Provisioning Status` over the `Host Status`. Clusters and Application Deployment ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ * Even though deployment profile override values are present, they do not appear in the deployment package application details pop-up screen. * Temporary inconsistent states in the user interface between deployments and cluster can show incorrect information on the dashboard. * Occasionally, because of inconsistency in handling cluster status, some deployments are shown as `Down` but the applications are shown as `Running`. The applications' state is the correct one. * When creating a cluster, you must select a region and a site but the region and site are not automatically added to the cluster's deployment metadata. You must add them as deployment metadata manually if you desire. * Any USB peripherals connected to the edge node can be connected to a VM-based application. However, although the USB peripheral(s) are detached from the edge node, the VM-based application will still have the USB peripherals connected. In this situation, when you run applications requiring USB peripherals, it will fail. * The same USB peripheral cannot be shared between the same type of applications, while the same USB peripheral can be simultaneously connected to the different types of applications. In other words, at the same time, multiple container-based applications cannot occupy the same USB peripheral, and the same USB peripheral cannot be connected to multiple VM-based applications. However, a container-based application and a VM-based application can have the same USB peripheral, which can lead to one of both applications crashing because of the USB sharing. Ensure that both the virtualization package for VM-based applications and the USB package for container-based applications do not have the same USB peripheral in their `usbList` configuration. This prevents a container and VM-based application from sharing the same USB peripheral, simultaneously. * Support for in-place upgrades of Edge Node Kubernetes cluster versions is currently not available. This is to be addressed in a future release. Currently in 3.0, Cluster upgrade can done by deleting the cluster and recreating with a new cluster template version. * Mulit-Node Cluster Provision is not supported in this release. This is to be addressed in future releases. * Cluster templates can be deleted even if they are actively being used by existing clusters. This issue may lead to unintended consequences, such as the inability to manage or update clusters associated with the deleted template. A fix for this issue is planned for a future release. * AI applications from the earlier release - Intel® SceneScape version 2024.1.2, Intel® Edge Insights System version 2.0 enhanced, and Intel® Geti™ solution version 2.6.0 do not work on the 3.0 release. These applications will be available in future releases. * If an application containing CRDs is deployed and subsequently undeployed, it may leave behind orphaned CRDs and related cluster-level objects. This can lead to an `annotation validation` error when attempting to redeploy on the cluster. See :doc:`troubleshooting guide `. User Experience ^^^^^^^^^^^^^^^^^ * The Search feature in the Locations' hierarchical display (that is, Regions and Sites) does not display the correct search results. This known issue will be resolved in an upcoming release. * `Let's Encrypt` certificates and Certificate Authority (CA) are deployed by default. `Let's Encrypt` poses an issue where if the Certificate Authority is changed, the edge nodes will not trust the Product anymore. In such a case, you must reinstall the edge nodes. Advanced users can use their different CAs, therefore avoiding this issue. * For users without write permissions, the user interface may show some controls that require write permissions as enabled but this is only a user interface issue. The actions taken by the user will result in an error. In some cases, the error may just state that the operation has failed, without citing permission as the reason. * Users are not redirected to the login credentials screen when the authorization token expires in the Infrastructure tab. Instead, the user interface informs them that "Additional Permissions are Needed". As a workaround, click a different tab on the header bar to redirect to the login credentials screen. * The search field at the top of most table pages (for example, Cluster, Hosts) enables you to search the `Name` field and other selected fields within that table. While the `Name` field is always searchable, some columns are not included in the search. * Telemetry Orchestrator services (OpenTelemetry\* and Mimir\*) do not have role-based access authorization enabled in the southbound interfaces towards the edge node. * If the Product and Keycloak\* solution are restarted separately or if there is a Keycloak signing key rotation, the Product returns error 403. The workaround is to log out, close the browser, and wait approximately 15 minutes and then log back in and retry; the request should succeed as soon as the Product refreshes the new signing keys from Keycloak solution, which happens periodically and automatically. * The querying capabilities of Mimir on orchestrator-observability and edgenode-observability may occasionally fail due to loss of communication between querier and query-frontend. The workaround is a restart of querier pod through Argo CD tool. * A configurable toggle for FDE and secure boot (SB) is available during host configuration and is usable even if the edge node goes through zero-touch provisioning (ZTP). When provisioning through the ZTP, you can disable the toggle because it has no effect. * When the License expires on an edge node, the status will show `No License`. You will need to provide the license, then a `LaunchCheck` will start to download a valid license every 60 seconds and will retry up to 10 times, for a total of 1 hour. If no license is obtained after 10 retries, the EN will be rebooted as part of the enforcement process. * If the expiration date of an edge node is pre-set to an earlier date than its original expiration on the IRC portal, after the edge node is fully provisioned, the edge node will not show a license error and will still be able to run with a valid license. * Occasionally, a reboot of the Product makes the Argo CD tool's `root-app` and `secret-config` remain in the `provisioning` state, and prevented creation of application deployment. The only known workaround is to reinstall the Product. * When the edge node is running, if the network connection is moved from one interface to another interface on the edge node, there will be a delay of approximately 15 minutes before all edge node agents reconnect to the Product. * After configuring an edge node and agreeing to create a cluster the user is able to start populating fields within the Create Cluster screen. However, if the nodes pass the "Secure Boot MATCH" stage of provisioning, any inputs entered may be lost. The workaround is to confirm the cluster creation inputs prior to this stage or to re-enter the values if they are lost. * You will notice a failed Kubernetes job when looking at the platform-keycloak deployment in Argo CD tool. There is a `known issue `_ in the bitnami/keycloak-config-cli job when used with Keycloak solution version 1. The job will fail with an unrecognized field "hideOnLogin". You can ignore this error because this field is not critical to Edge Manageability Framework. * During Interactive Onboarding after the 3rd failed attempt to provide the password the installation proceeds but has not obtained a valid JWT token, thus failing to onboard the node. * During host state transitions, briefly such as registered to onboarded or configured and also active to deleted, the user interface might briefly show an outdated and/or inconsistent state. * On the rare event that the Org-Admin-Group is not created in keycloak, restarting the keycloak-tenant-controller pod via the Argo CD UI will force the initial roles and groups to be recreated. * Users created in Keycloak must have email address set up to properly perform authentication to Grafana Observability Dashboards. Users without email set won't be able to access metrics and logs via Grafana UI. * On ASRock platform the hardware resources are not displayed properly in the Infrastructure tab, this has no impact on functionality of the nodes for cluster or application installation. Limitations --------------------------------------------------------------------- The following are known issues in the release. While several know issues and limitations have been addressed during the 3.0 release cycle, some have been carried over from past releases. Provisioning Limitations ^^^^^^^^^^^^^^^^^^^^^^^^^ * The proxy server could not be configured in the OS profile, thus this setting is unavailable. The proxy server could not be used to connect the edge node to the Product. * An edge node cannot be provisioned or operated behind a customer provided Internet proxy server. * An edge node cannot be re-provisioned from scratch if it is not deleted first from the user interface. Follow the steps in :doc:`/user_guide/set_up_edge_infra/delete_host` and then re-provision the edge node. * For cloud-based onboarding, the µOS download during provisioning may run up to 30 minutes because of Ethernet packet processing latencies associated with the UEFI networking driver. * You cannot perform an initial boot behind a proxy server because the Original Equipment Manufacturer (OEM) BIOS does not support HTTPs booting behind a proxy server. After you have installed the OS, you can boot behind a proxy server. * In a corporate environment where the Product is installed on-premises behind a network proxy, the application [Dynamic Kit Adaptation Module (DKAM)] responsible for obtaining EN installation artifacts fails to download the necessary artifacts because of incorrect redirects to proxy and Intel Release Service. * The embedded JSON Web Token (JWT) in the µOS are programmed to expire after a maximum of 60 minutes. If there is a delay in supplying the login details, the OS provisioning process may fail, which is the expected behavior. In such cases, the user must initiate the re-provisioning of the edge node. * All hardware to be onboarded into the Edge Orchestrator must have a valid UUID and Serial Number as shown by the output of `dmidecode -s system-uuid` and dmidecode -s system-serial-number`. If the hardware does not have these correctly set, contact the vendor first. Hosts and Infrastructure Limitations ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ * GPU support: * Sharing of GPU resources between multiple applications on the same node is not supported yet. * GPU metrics collection is not supported yet. * GPU is not detected and reported on the ASUS\* PE3000G system. * Persistent volumes: * Local volumes are accessible only from every single node, thus local volumes are subject to the availability of the underlying node and are not suitable for all applications. * If a node becomes unhealthy, then the local volume will also become inaccessible, and an application using it will not run. * The Dell\* EMC PowerEdge XR12 server with PCIe\* storage controller (`HBA355i `_) is not supported by the cloud-based provisioning process. Remove this RAID controller from your node. * The Product does not differentiate P-cores and E-cores in Intel :sup:`®` Core™ processor-based platforms. * You can create two sites with the same name under two different regions, although this does not cause the nodes to be present when creating clusters. Intel recommends that sites have unique, non-overlapping names. Clusters and Application Deployment Limitations ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ * A deployment package cannot be created by including two applications with the same name but with different publishers or versions. Do not include two applications with the same name in a single deployment project. You can modify the name of one of the applications if required. * Parameter template variable names do not support the underscore `_` char. For example, `parameter_name=models_repository.image.tag` is not valid. If revising the Helm\* chart for the application to remove `_` is not viable, use multiple profiles for that application. * Multiple "-" (for example, `1.0.0-dev-test`) characters are not allowed in an application's chart or version during creation. * The maximum number of unique deployments is limited to 300 per Product instance. This limitation spawns from the AWS service used in the backend. Based on the number of edge nodes, each deployment can have multiple running instances. * You must not modify the extension deployment packages (SR-IOV, Virtualization, Load Balancer, Intel® GPU) and cluster templates (restricted, baseline, and privileged). These are automatically created when the Product is installed. * When you use "%GeneratedDockerCredential%" in the Application Profile, any updates made to the image registry in Catalog are not automatically applied to existing deployments. To update the image pull secret, you must recreate the existing deployments. `_. * When you create deployments to multiple target clusters, some deployments show error status messages rarely, even though all Kubernetes resources are created correctly. This is an issue in the Fleet agent and was fixed by the Fleet community but not released yet. To resolve it, go to Rancher UI > Continuous Delivery > Cluster and then click the "Force Update" button. * Changes to a host’s labels (update, removal) performed after the cluster has already been created will not be propagated to the corresponding Kubernetes nodes. This has been documented internally and a fix for this issue will be provided in the next release. * Bundle-Deployments for Application/Extension Deployments in Automatic Mode of deployment are not cleaned-up on the Cluster Deletion. This results in showing any errors from these deployments in subsequent successful deployments. Refer :ref:`deploymentpage_errors`. Multi-tenancy Limitations ^^^^^^^^^^^^^^^^^^^^^^^^^ * If you add a user to many groups that provide project access, some Edge Orchestrator functionality may fail because of size limits for the authorization token used in a web browser. As an example, as user added to more than five groups of type `group_projectid_edgemanagergroup` or `group_projectid_edgeoperatorgroup` (combined), or 10 groups of type `group_projectid_hostmanagergroup` may experience this failure. As a workaround, reduce the total number of groups that a single user is a member of or create separate users. User Experience Limitations ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ * Cluster labels (metadata) for both names and values fields must be in lowercase; otherwise, the system becomes inconsistent. The user interface flags these fields as an error but does not block the user from continuing and saving the cluster with mixed-case cluster label values assigned. * Site name must be unique across all regions, that is, no two sites can have the same name in the Product deployment. Otherwise, the host allocated to one of the overlapping names might not appear in the user interface. * Remote access to the node is supported only at the virtual machine console and the kube-shell level. It is not user-supported at the OS level. * The OpenTelemetry Collector service on the edge node host acts as the single gateway for forwarding all logs (host agents and cluster) and hardware metrics to the Product. If the Collector service fails, then these logs and metrics will not be sent to the Product until the service is restored. * The `Show All` page size for hosts does not work for lists over 100. If you have a list of more than 100 hosts in a view, do not set the page size to larger than 100. * In the Observability Dashboard, hosts are present and can be selected in the drop-down for a query that spans a period where a node was at least partially there. For example, if the node went down 4 minutes ago and the metric query is set for 5 the metrics for the host `down` will be present. Also, if you choose a time period in time where the host did exist, then the host will be displayed in the dropdown. Wait until the proper refresh time. * Accessing more than one edge web application at a time in a browser through the Service Link feature (Application Service Proxy) is not supported. The workaround is to open a second application in an incognito window or a different browser. * Scheduling a recurring maintenance to happen on the last day of the month before midnight in a timezone that is behind GMT/UTC, when the schedule is after midnight in GMT/UTC causes the maintenance to be scheduled on the 1st of the selected month instead of the next month. For example, if you schedule a maintenance to repeat every May 31st at 9 pm PDT, the maintenance will repeat on May 1st at 9 pm instead of on June 31st. When scheduling, be aware of the time zone. * While using Safari as a browser, you may encounter some graphical inconsistencies, such as erroneous font characters. These are appearance issues and do not impede any functionality. * Until an Edge Node JWT token is valid, a provisioned Edge Node can reach the Edge Orchestrator. If you issue a delete of the host, the host is fully deleted from Edge Orchestrator, but still retains the certificates, thus if it's re-registered with the correct information it will immediately re-connect to the Edge Orchestrator but it will be rejected by the Edge Orchestrator APIs. Upon token expiry (at most 1 hour) the reconnection will not happen. * The "Total Provisioning Time" metric is only available for approximately 15 days since a node was provisioned. * The hosts table's `Operating System` column does not show the desired OS for `Registered` hosts. It will only show the current OS of `Provisioned` hosts. You can view the desired OS of a host on the host details page under `Updates`. Recommendations --------------------- * Users need to maintain fixed IP reservations for each edge node using address-to-MAC mapping in their DHCP server for stable functioning of the edge node cluster. * Intel advises against scheduling a major OS upgrade. Intel only supports the current Product version on Ubuntu\* OS 22.04 LTS. * Wait for some time after the initial Product installation or a full restart before provisioning nodes because there are a few components (for example, DKAM and Tinkerbell pods) that take about 15 minutes to get to the ready state. * Wait for some time after the initial Product installation or a complete system reboot before provisioning nodes. This is because certain components, such as DKAM and Tinkerbell pods, need approximately 15 minutes to reach the ready state.
