Troubleshooting virtual machines

If a virtual machine fails to deploy

Review the error message on the VM right pane. One of the possible root causes is that compute nodes lack free RAM or CPU resources to host the VM.

If a virtual machine is in the error state

Examine the VM history in the History tab on the VM right pane. The event log will contain all of the VM management operations performed by users in the user or command-line interface. You can expand each log entry to view operation details by clicking the arrow icon next to it. The details include the operation name, date and time, status, initiator, and request ID.

If a virtual machine is stuck in a failed or transitional state

Reset the VM to its last stable state: active, shut down or shelved:

  1. Click the stuck VM.
  2. On the VM right pane, click Reset state.

If a virtual machine fails to boot

Examine the VM console log by clicking Download console log on the VM right pane. The log will contain log messages only if logging is enabled inside the VM (refer to Enabling logging for virtual machines).
