Xen devel - Feb 2005 - swap space considered in domain save?

I have some DSM application which use large swap space. I have used domain save
for checkpointing two virtual machines, and then keep them running for a while.
When I rolled back the two machines my DSM application just hangs there. I am
just wondering if used swap space is stored in the machine state? (the answer
seems to be no to me)

Correct: no on-disk state is stored during a save.  If you want that, you need 
to use some other means to snapshot the disk.

Cheers,
