Chapter 15. Support 15.1. Support overview You can request assistance from Red Hat Support, report bugs, collect data about your environment, and monitor the health of your cluster and virtual machines (VMs) with the following tools. 15.1.1. Opening support tickets If you have encountered an issue that requires immediate assistance from Red Hat Support, you can submit a support case. To report a bug, you can create a Jira issue directly. 15.1.1.1. Submitting a support case To request support from Red Hat Support, follow the instructions for submitting a support case . It is helpful to collect debugging data to include with your support request. 15.1.1.1.1. Collecting data for Red Hat Support You can gather debugging information by performing the following steps: Collecting data about your environment Configure Prometheus and Alertmanager and collect must-gather data for OpenShift Container Platform and OpenShift Virtualization. must-gather tool for OpenShift Virtualization Configure and use the must-gather tool. Collecting data about VMs Collect must-gather data and memory dumps from VMs. 15.1.1.2. Creating a Jira issue To report a bug, you can create a Jira issue directly by filling out the form on the Create Issue page. 15.1.2. Web console monitoring You can monitor the health of your cluster and VMs by using the OpenShift Container Platform web console. The web console displays resource usage, alerts, events, and trends for your cluster and for OpenShift Virtualization components and resources. Table 15.1. Web console pages for monitoring and troubleshooting Page Description Overview page Cluster details, status, alerts, inventory, and resource usage Virtualization Overview tab OpenShift Virtualization resources, usage, alerts, and status Virtualization Top consumers tab Top consumers of CPU, memory, and storage Virtualization Migrations tab Progress of live migrations VirtualMachines VirtualMachine VirtualMachine details Metrics tab VM resource usage, storage, network, and migration VirtualMachines VirtualMachine VirtualMachine details Events tab List of VM events VirtualMachines VirtualMachine VirtualMachine details Diagnostics tab VM status conditions and volume snapshot status 15.2. Collecting data for Red Hat Support When you submit a support case to Red Hat Support, it is helpful to provide debugging information for OpenShift Container Platform and OpenShift Virtualization by using the following tools: must-gather tool The must-gather tool collects diagnostic information, including resource definitions and service logs. Prometheus Prometheus is a time-series database and a rule evaluation engine for metrics. Prometheus sends alerts to Alertmanager for processing. Alertmanager The Alertmanager service handles alerts received from Prometheus. The Alertmanager is also responsible for sending the alerts to external notification systems. For information about the OpenShift Container Platform monitoring stack, see About OpenShift Container Platform monitoring . 15.2.1. Collecting data about your environment Collecting data about your environment minimizes the time required to analyze and determine the root cause. Prerequisites Set the retention time for Prometheus metrics data to a minimum of seven days. Configure the Alertmanager to capture relevant alerts and to send alert notifications to a dedicated mailbox so that they can be viewed and persisted outside the cluster. Record the exact number of affected nodes and virtual machines. Procedure Collect must-gather data for the cluster . Collect must-gather data for Red Hat OpenShift Data Foundation , if necessary. Collect must-gather data for OpenShift Virtualization . Collect Prometheus metrics for the cluster . 15.2.2. Collecting data about virtual machines Collecting data about malfunctioning virtual machines (VMs) minimizes the time required to analyze and determine the root cause. Prerequisites Linux VMs: Install the latest QEMU guest agent . Windows VMs: Record the Windows patch update details. Install the latest VirtIO drivers . Install the latest QEMU guest agent . If Remote Desktop Protocol (RDP) is enabled, connect by using the desktop viewer to determine whether there is a problem with the connection software. Procedure Collect must-gather data for the VMs using the /usr/bin/gather script. Collect screenshots of VMs that have crashed before you restart them. Collect memory dumps from VMs before remediation attempts. Record factors that the malfunctioning VMs have in common. For example, the VMs have the same host or network. 15.2.3. Using the must-gather tool for OpenShift Virtualization You can collect data about OpenShift Virtualization resources by running the must-gather command with the OpenShift Virtualization image. The default data collection includes information about the following resources: OpenShift Virtualization Operator namespaces, including child objects OpenShift Virtualization custom resource definitions Namespaces that contain virtual machines Basic virtual machine definitions Instance types information is not currently collected by default; you can, however, run a command to optionally collect it. Procedure Run the following command to collect data about OpenShift Virtualization: USD oc adm must-gather \ --image=registry.redhat.io/container-native-virtualization/cnv-must-gather-rhel9:v4.18.0 \ -- /usr/bin/gather 15.2.3.1. must-gather tool options You can run the oc adm must-gather command to collect must gather images for all the Operators and products deployed on your cluster without the need to explicitly specify the required images. Alternatively, you can specify a combination of scripts and environment variables for the following options: Collecting detailed virtual machine (VM) information from a namespace Collecting detailed information about specified VMs Collecting image, image-stream, and image-stream-tags information Limiting the maximum number of parallel processes used by the must-gather tool 15.2.3.1.1. Parameters Environment variables You can specify environment variables for a compatible script. NS=<namespace_name> Collect virtual machine information, including virt-launcher pod details, from the namespace that you specify. The VirtualMachine and VirtualMachineInstance CR data is collected for all namespaces. VM=<vm_name> Collect details about a particular virtual machine. To use this option, you must also specify a namespace by using the NS environment variable. PROS=<number_of_processes> Modify the maximum number of parallel processes that the must-gather tool uses. The default value is 5 . Important Using too many parallel processes can cause performance issues. Increasing the maximum number of parallel processes is not recommended. Scripts Each script is compatible only with certain environment variable combinations. /usr/bin/gather Use the default must-gather script, which collects cluster data from all namespaces and includes only basic VM information. This script is compatible only with the PROS variable. /usr/bin/gather --vms_details Collect VM log files, VM definitions, control-plane logs, and namespaces that belong to OpenShift Virtualization resources. Specifying namespaces includes their child objects. If you use this parameter without specifying a namespace or VM, the must-gather tool collects this data for all VMs in the cluster. This script is compatible with all environment variables, but you must specify a namespace if you use the VM variable. /usr/bin/gather --images Collect image, image-stream, and image-stream-tags custom resource information. This script is compatible only with the PROS variable. /usr/bin/gather --instancetypes Collect instance types information. This information is not currently collected by default; you can, however, optionally collect it. 15.2.3.1.2. Usage and examples Environment variables are optional. You can run a script by itself or with one or more compatible environment variables. Table 15.2. Compatible parameters Script Compatible environment variable /usr/bin/gather * PROS=<number_of_processes> /usr/bin/gather --vms_details * For a namespace: NS=<namespace_name> * For a VM: VM=<vm_name> NS=<namespace_name> * PROS=<number_of_processes> /usr/bin/gather --images * PROS=<number_of_processes> Syntax To collect must-gather logs for all Operators and products on your cluster in a single pass, run the following command: USD oc adm must-gather --all-images If you need to pass additional parameters to individual must-gather images, use the following command: USD oc adm must-gather \ --image=registry.redhat.io/container-native-virtualization/cnv-must-gather-rhel9:v4.18.0 \ -- <environment_variable_1> <environment_variable_2> <script_name> Default data collection parallel processes By default, five processes run in parallel. USD oc adm must-gather \ --image=registry.redhat.io/container-native-virtualization/cnv-must-gather-rhel9:v4.18.0 \ -- PROS=5 /usr/bin/gather 1 1 You can modify the number of parallel processes by changing the default. Detailed VM information The following command collects detailed VM information for the my-vm VM in the mynamespace namespace: USD oc adm must-gather \ --image=registry.redhat.io/container-native-virtualization/cnv-must-gather-rhel9:v4.18.0 \ -- NS=mynamespace VM=my-vm /usr/bin/gather --vms_details 1 1 The NS environment variable is mandatory if you use the VM environment variable. Image, image-stream, and image-stream-tags information The following command collects image, image-stream, and image-stream-tags information from the cluster: USD oc adm must-gather \ --image=registry.redhat.io/container-native-virtualization/cnv-must-gather-rhel9:v4.18.0 \ /usr/bin/gather --images Instance types information The following command collects instance types information from the cluster: USD oc adm must-gather \ --image=registry.redhat.io/container-native-virtualization/cnv-must-gather-rhel9:v4.18.0 \ /usr/bin/gather --instancetypes 15.3. Troubleshooting OpenShift Virtualization provides tools and logs for troubleshooting virtual machines (VMs) and virtualization components. You can troubleshoot OpenShift Virtualization components by using the tools provided in the web console or by using the oc CLI tool. 15.3.1. Events OpenShift Container Platform events are records of important life-cycle information and are useful for monitoring and troubleshooting virtual machine, namespace, and resource issues. VM events: Navigate to the Events tab of the VirtualMachine details page in the web console. Namespace events You can view namespace events by running the following command: USD oc get events -n <namespace> See the list of events for details about specific events. Resource events You can view resource events by running the following command: USD oc describe <resource> <resource_name> 15.3.2. Pod logs You can view logs for OpenShift Virtualization pods by using the web console or the CLI. You can also view aggregated logs by using the LokiStack in the web console. 15.3.2.1. Configuring OpenShift Virtualization pod log verbosity You can configure the verbosity level of OpenShift Virtualization pod logs by editing the HyperConverged custom resource (CR). Procedure To set log verbosity for specific components, open the HyperConverged CR in your default text editor by running the following command: USD oc edit hyperconverged kubevirt-hyperconverged -n openshift-cnv Set the log level for one or more components by editing the spec.logVerbosityConfig stanza. For example: apiVersion: hco.kubevirt.io/v1beta1 kind: HyperConverged metadata: name: kubevirt-hyperconverged spec: logVerbosityConfig: kubevirt: virtAPI: 5 1 virtController: 4 virtHandler: 3 virtLauncher: 2 virtOperator: 6 1 The log verbosity value must be an integer in the range 1-9 , where a higher number indicates a more detailed log. In this example, the virtAPI component logs are exposed if their priority level is 5 or higher. Apply your changes by saving and exiting the editor. 15.3.2.2. Viewing virt-launcher pod logs with the web console You can view the virt-launcher pod logs for a virtual machine by using the OpenShift Container Platform web console. Procedure Navigate to Virtualization VirtualMachines . Select a virtual machine to open the VirtualMachine details page. On the General tile, click the pod name to open the Pod details page. Click the Logs tab to view the logs. 15.3.2.3. Viewing OpenShift Virtualization pod logs with the CLI You can view logs for the OpenShift Virtualization pods by using the oc CLI tool. Procedure View a list of pods in the OpenShift Virtualization namespace by running the following command: USD oc get pods -n openshift-cnv Example 15.1. Example output NAME READY STATUS RESTARTS AGE disks-images-provider-7gqbc 1/1 Running 0 32m disks-images-provider-vg4kx 1/1 Running 0 32m virt-api-57fcc4497b-7qfmc 1/1 Running 0 31m virt-api-57fcc4497b-tx9nc 1/1 Running 0 31m virt-controller-76c784655f-7fp6m 1/1 Running 0 30m virt-controller-76c784655f-f4pbd 1/1 Running 0 30m virt-handler-2m86x 1/1 Running 0 30m virt-handler-9qs6z 1/1 Running 0 30m virt-operator-7ccfdbf65f-q5snk 1/1 Running 0 32m virt-operator-7ccfdbf65f-vllz8 1/1 Running 0 32m View the pod log by running the following command: USD oc logs -n openshift-cnv <pod_name> Note If a pod fails to start, you can use the -- option to view logs from the last attempt. To monitor log output in real time, use the -f option. Example 15.2.

Guest system logs Viewing the boot logs of VM guests can help diagnose issues. You can configure access to guests' logs and view them by using either the OpenShift Container Platform web console or the oc CLI. This feature is disabled by default. If a VM does not explicitly have this setting enabled or disabled, it inherits the cluster-wide default setting. Important If sensitive information such as credentials or other personally identifiable information (PII) is written to the serial console, it is logged with all other visible text. Red Hat recommends using SSH to send sensitive data instead of the serial console. 15.3.3.1. Enabling default access to VM guest system logs with the web console You can enable default access to VM guest system logs by using the web console. Procedure From the side menu, click Virtualization Overview . Click the Settings tab. Click Cluster Guest management . Set Enable guest system log access to on. 15.3.3.2. Enabling default access to VM guest system logs with the CLI You can enable default access to VM guest system logs by editing the HyperConverged custom resource (CR). Procedure Open the HyperConverged CR in your default editor by running the following command: USD oc edit hyperconverged kubevirt-hyperconverged -n openshift-cnv Update the disableSerialConsoleLog value. For example: kind: HyperConverged metadata: name: kubevirt-hyperconverged spec: virtualMachineOptions: disableSerialConsoleLog: true 1 #... 1 Set the value of disableSerialConsoleLog to false if you want serial console access to be enabled on VMs by default. 15.3.3.3. Setting guest system log access for a single VM with the web console You can configure access to VM guest system logs for a single VM by using the web console. This setting takes precedence over the cluster-wide default configuration. Procedure Click Virtualization VirtualMachines from the side menu. Select a virtual machine to open the VirtualMachine details page. Click the Configuration tab. Set Guest system log access to on or off. 15.3.3.4. Setting guest system log access for a single VM with the CLI You can configure access to VM guest system logs for a single VM by editing the VirtualMachine CR. This setting takes precedence over the cluster-wide default configuration. Procedure Edit the virtual machine manifest by running the following command: USD oc edit vm <vm_name> Update the value of the logSerialConsole field. For example: apiVersion: kubevirt.io/v1 kind: VirtualMachine metadata: name: example-vm spec: template: spec: domain: devices: logSerialConsole: true 1 #... 1 To enable access to the guest's serial console log, set the logSerialConsole value to true . Apply the new configuration to the VM by running the following command: USD oc apply vm <vm_name> Optional: If you edited a running VM, restart the VM to apply the new configuration. For example: USD virtctl restart <vm_name> -n <namespace> 15.3.3.5. Viewing guest system logs with the web console You can view the serial console logs of a virtual machine (VM) guest by using the web console. Prerequisites Guest system log access is enabled. Procedure Click Virtualization VirtualMachines from the side menu. Select a virtual machine to open the VirtualMachine details page. Click the Diagnostics tab.

Common error messages The following error messages might appear in OpenShift Virtualization logs: ErrImagePull or ImagePullBackOff Indicates an incorrect deployment configuration or problems with the images that are referenced. 15.3.6. Troubleshooting data volumes You can check the Conditions and Events sections of the DataVolume object to analyze and resolve issues. 15.3.6.1. About data volume conditions and events You can diagnose data volume issues by examining the output of the Conditions and Events sections generated by the command: USD oc describe dv <DataVolume> The Conditions section displays the following Types : Bound Running Ready The Events section provides the following additional information: Type of event Reason for logging Source of the event Message containing additional diagnostic information. The output from oc describe does not always contains Events . An event is generated when the Status , Reason , or Message changes. Both conditions and events react to changes in the state of the data volume. For example, if you misspell the URL during an import operation, the import generates a 404 message. That message change generates an event with a reason. The output in the Conditions section is updated as well. 15.3.6.2. Analyzing data volume conditions and events By inspecting the Conditions and Events sections generated by the describe command, you determine the state of the data volume in relation to persistent volume claims (PVCs), and whether or not an operation is actively running or completed. You might also receive messages that offer specific details about the status of the data volume, and how it came to be in its current state. There are many different combinations of conditions. Each must be evaluated in its unique context. Examples of various combinations follow. Bound - A successfully bound PVC displays in this example. Note that the Type is Bound , so the Status is True . If the PVC is not bound, the Status is False . When the PVC is bound, an event is generated stating that the PVC is bound. In this case, the Reason is Bound and Status is True . The Message indicates which PVC owns the data volume. Message , in the Events section, provides further details including how long the PVC has been bound ( Age ) and by what resource ( From ), in this case datavolume-controller : Example output Status: Conditions: Last Heart Beat Time: 2020-07-15T03:58:24Z Last Transition Time: 2020-07-15T03:58:24Z Message: PVC win10-rootdisk Bound Reason: Bound Status: True Type: Bound ... Events: Type Reason Age From Message ---- ------ ---- ---- ------- Normal Bound 24s datavolume-controller PVC example-dv Bound Running - In this case, note that Type is Running and Status is False , indicating that an event has occurred that caused an attempted operation to fail, changing the Status from True to False . However, note that Reason is Completed and the Message field indicates Import Complete . In the Events section, the Reason and Message contain additional troubleshooting information about the failed operation. In this example, the Message displays an inability to connect due to a 404 , listed in the Events section's first Warning . From this information, you conclude that an import operation was running, creating contention for other operations that are attempting to access the data volume: Example output Status: Conditions: Last Heart Beat Time: 2020-07-15T04:31:39Z Last Transition Time: 2020-07-15T04:31:39Z Message: Import Complete Reason: Completed Status: False Type: Running ... Events: Type Reason Age From Message ---- ------ ---- ---- ------- Warning Error 12s (x2 over 14s) datavolume-controller Unable to connect to http data source: expected status code 200, got 404. Status: 404 Not Found Ready - If Type is Ready and Status is True , then the data volume is ready to be used, as in the following example. If the data volume is not ready to be used, the Status is False : Example output Status: Conditions: Last Heart Beat Time: 2020-07-15T04:31:39Z Last Transition Time: 2020-07-15T04:31:39Z Status: True Type: Ready
