RE: [Xen-users] Hotplug scripts not working after today''s checkout

The error is misleading. 
Make sure your vifs are all started up. To isolate the problem comment
out the vif line in the configfile and try again.

Double-check the permissions on the hotplug scripts - I''ve seen this
behavior caused by a missing execute bit.

If that doesn''t help, turn on udev debug-level logging (either in
/etc/udev/udev.conf or via udevcontrol)

Cheers
