Hi,
I''m running FC7 with the 2.6.20-2931.fc7xen kernel and used
virt-manager to configure a xp guest domain.
I receive the following message after trying to run the xp guest:
virsh # start xp
(xend.err ''Device 0 (vif) could not be connected. Hotplug scripts not
working.'')
virsh # dumpxml xp
<domain type=''xen'' id=''-1''>

winxp.iso one provided in such a way:
dd if=/dev/cdrom of=/var/lib/xen/images/winxp.iso
for an assistance I am very grateful,
