Hi Michael,
Keep us informed if you pull that off... I'm interested in that
functionality as well, for similar reasons.
For what it's worth, on the torque mailing list I remember that somebody
had a script for instantiating and destroying a VM on job start/end.
Can't remember who or what, but it's worth checking out the mailing
archives for that (sorry, rushing at the moment so no time to do it).
cheers,
Luc

Snapshot restart would only work for you if your application leaves

the program does not checkpoint to disk.
my cursory look through the kvm manual seemed to instigate that the
qcow2 image also snaps the memory into the image. i can't argue the
point one way or the other though.
the functionality that I hope exists is; pause a VM (cpu/memory/disk),
save it all off into a file, then some point later resume the saved
off image exactly where it was paused like nothing happened
whether it works that way or not, i can't say, that's what i was going to test.
