I've got the same problem with my xen-3.0_7608-2.1 SUSE 10 Dom0.
The funny thing is that running some RHEL 4 guest works fine,
while a SUSE 10 guest waits for some timeout then comes back with an error:

# xm create hamster -c
Using config file "/etc/xen/hamster".
Error: Error creating domain: Device 769 (vbd) could not be connected. Hotplug
scripts not working

(so this looks like if I have to patch the guest OS somehow?)
