[pve-devel] successfull migration but failed resume

[Alexandre DERUMIER]

>>No idea as proxmox kills the target kvm proces if the migration fails. 
Not true for the last phase, resume is done is phase3_cleanup.

I have done the test, using a "die" instead "qmp cont" command in resume task, the migration task finish with error,
but the target vm is in pause. I just need to resume it.


>>But not crashed i don't see a segfault. Most probably paused. 

Maybe my patch will show more info if it's happen again...

No idea as proxmox kills the target kvm proces if the migration fails. 
But not crashed i don't see a segfault. Most probably paused.
