libvirt users - Jul 2012 - save / restore RAM state - Problem

Hi all,

i am trying (test) to save / restore a state of a winxp virtual machine.
Perhaps i am missing that i can not restore save image to LVM partition.

PEBKAC problem

RTFM was the solution

virsh # save winxp /root/winxp.save

Domain winxp saved to /root/winxp.save

virsh # restore /root/winxp.save
Domain restored from /root/winxp.save


sorry for the SPAM
