Troubleshooting a KVM discovery or a validate operation

Discovery or Validate operation fails for the KVM host

Recommended action: Ensure sure that the KVM host is reachable and that NetBackup services are up.

A backup of a virtual machine without a storage pool cannot be restored to the original location

If the virtual machine disk files did not reside on the storage pool during the backup, the pre-recovery check fails if the user attempts to restore to the original location. In this case, restore to an alternate location. By default for this kind of restore, the Destination storage pool and the Destination volume values are empty for the virtual machine. Select the wanted values before you continue with the restore.

A backup job fails with error 4726 - Failed to create snapshot of the specified VM.

The bpbrm logs on the media server contain the following message:

This error can occur if the Virtual machine quiesce option is selected without the option Perform snapshot without quiescing if quiesced snapshots fail for the backup policy.

A snapshot may fail if the virtual machine can't be quiesced. This error usually means that the QEMU agent isn't installed or isn't running on the guest system. To fix this issue, you can either resolve the QEMU agent issue on the guest VM to allow for a successful quiesce operation. Or, select the option Perform snapshot without quiescing if quiesced snapshots fail option.

A backup of a virtual machine fails if the QEMU guest agent is not installed

The KVM advanced attribute Virtual machine quiesce is enabled by default and requires that the QEMU guest agent is installed. If not, the backup fails.
