Subject: [PATCHv1 0/5] tools: rework VM Generation ID
Date: Wed, 21 May 2014 14:21:02 +0100 [thread overview]
Message-ID: <1400678467-23559-1-git-send-email-david.vrabel@citrix.com> (raw)
This series reworks the VM Generation ID to a) conform to the
published spec from Microsoft; b) simplify the save/restore code; and
c) extend the libxl API to allow toolstacks to use this feature.
The VM Generation ID must be regenerated with a new random ID after
certain VM operations. For xl, a new ID is required when restoring
from a saved image (but not after a migration, reboot, pause/unpause).
Can someone advise on the best way to implement this in xl?
We could put a vm-generation-id variable in the domain configuration
file. This would end up in the saved configuration file and would be
reused or regenerated on restore depending on whether the domain was
migrated or restored from a file.
You can download the spec from:
