You might want to look into external snapshots as a more efficient way
of taking guest snapshots. With virsh managedsave/start, you are
guaranteed guest downtime of several seconds at a minimum, and you have
to do the disk management yourself; but with external snapshots, you can
take a consistent picture of guest state at a point in time with
sub-second downtime (the same way live migration between hosts has
sub-second downtime).
I'm coming back to say that we now have a working solution in production
based on external snapshots. It's written in python to execute to
process detailed in this thread. The downtime is a few seconds.
Thanks again.
