Subject: [PATCHv2 0/6] tools: rework VM Generation ID
Date: Tue, 27 May 2014 18:31:43 +0100 [thread overview]
Message-ID: <1401211909-27771-1-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. Since xl lacks infrastructure for tracking the
life-cycle of snapshots and clones (etc), the safe option of always
using a new generation ID is used.
You can download the spec from:
http://www.microsoft.com/en-us/download/details.aspx?id=30707
Changes in v2:
- Use libxl_uuid for the generation ID.
- Add "generation_id" option to xl domain configuration file and use
this to set a random generation ID every time.
