A user (Joshua) is reporting that 'xm restore' isn't working when GPLPV
is involved. I've checked the logs generated by GPLPV and there are no
problems on the save side of things that I can see. Is there anything
extra that the suspend or restore needs to do since 3.4.x?
Joshua has captured the following:
On the dom0 I initiated a "xm save" of the VM. No problems here, but
when I initiate an "xm restore", I receive the following error:
Error: /usr/lib64/xen/bin/xc_restore 56 103 2 3 1 1 1 failed
And in /var/log/xen/xend.log, I see (pertaining to this event):
