1.3.3. ISSU error handling

systemctl restart virtual-accelerator.target

The service restart command can be used at any time during ISSU procedure to cancel the ISSU procedure and restart the Virtual Accelerator without ISSU.

All ISSU commands returns an error status. If an error occured during command processing, Virtual Accelerator should be restarted in slow mode using service restart command. It will fallback on slow restart mode, and will ensure that the service is properly restarted even if an error occured during ISSU procedure.
