[libvirt] Using Restore in another host.

[Michal Novotny]

Hi,
the interesting thing is the "Permission denied" message in the log file:

LC_ALL=C
PATH=/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/sbin:/sbin:/bin
QEMU_AUDIO_DRV=none /usr/bin/qemu-system-x86_64 -S -M pc-0.12

cat: -: Permission denied <== THIS ONE

I don't know much about the internal libvirt design since libvirt is not
my primary space so I hope my e-mails from yesterday helped a little but
I'll leave the rest for libvirt guys since I'm not having any other
ideas what could be wrong there.
