XenCenter

VM Recovery Mode

Note:

XenCenter YYYY.x.x is currently in preview and is not supported for production use. Note that any future references to production support apply only when XenCenter YYYY.x.x and XenServer 8 go from preview status to general availability.

You can use XenCenter YYYY.x.x to manage your XenServer 8 and Citrix Hypervisor 8.2 CU1 non-production environments. However, to manage your Citrix Hypervisor 8.2 CU1 production environment, use XenCenter 8.2.7. For more information, see the XenCenter 8.2.7 documentation.

You can install XenCenter 8.2.7 and XenCenter YYYY.x.x on the same system. Installing XenCenter YYYY.x.x does not overwrite your XenCenter 8.2.7 installation.

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.
