Hi,

# cat /etc/release

After fresh install of Solaris 10u6 as hvm domU it cannot boot:

</domain>


So it cannot find the install image for the cdrom device.

A workaround for this:
# virsh detach-disk virt2 hdc

# virsh start virt2
Domain virt2 started

Build 107 is sadly broken, but there''s a simple fix. Edit
/usr/lib/xen/scripts/vbd-check and make line 44 or thereabouts read:

                if [ "$DEV" = "$device" ]; then

That is, add the quotes.

In general, looking at /var/log/xen/xpvd-event.log will show you hotplug
failures
