VM Recovery Mode

If you experience serious problems with a paravirtualized Linux VM, you can try starting it up in Recovery Mode. This process turns HVM mode on temporarily and sets the CD drive as the first boot. You can boot a rescue CD or rescue PXE and then investigate the cause of the problem.

To start a VM in Recovery Mode:

  • Select the VM that you want to start in recovery mode.
  • From the main menu, choose VM > Start/Shut down > Start in Recovery Mode.

    Note:

    Attach your usual operating system rescue CD, boot the VM from this CD, and then fix the VM from the rescue CD.

See VMs and Templates to find out more about HVM and paravirtualized modes.
