Thread: Virtual machine does not work after a save/restore (KVM)

hello,

have ubuntu server 10.04 kvm, extensions in bios enabled:

root@cluster03:~# kvm-ok
info: cpu supports kvm extensions
info: /dev/kvm exists
kvm acceleration can used

problem when save , restore after of virtual machine, screen freezes , ping not respond after restored.

i've disabled apparmor dissmiss problems , continues not working.

know why vm not restore normally?

lot!

pd: commands i'm using-->

virsh --connect qemu+ssh:///system save one-309 one-309
virsh --connect qemu+ssh:///system restore one-309



i've saved debug logs with:

export libvirt_log_outputs="1:file:virsh.log"

, output (if save logs level 2 or greater don't see log means kvm or libvirt doesn't detect error?):
