Great :) so it'll work for rbd or nexenta :)
>>Sorry, I do not understand what you mean?
When I have done tests with savevm, the qmp socket timeout each time during the vmstate save.
It's also take more time to take than using your vmstate file. (maybe because savevm write the state in the main volume and need to do space inside.).
>>qm start -stateuri <statefile>
Oh, yes, it should works. (like for migratation with statefile). I'll test that this morning.

The idea is to save the state into an external file. That will work for all storage

# qm start -stateuri <statefile>
should do the trick - but I have not tested that.
