There were two aspects:

 a) Fixing one of the Fedora xen RPM patches which
    caused all hotplug errors to be obscured with
    a python error about 'destroyDevice()

  * Thu Feb 15 2007 Daniel P. Berrange <berrange at redhat.com> - 3.0.3-6.fc6
  - Improve hotplug error reporting
  * Tue Jan 30 2007 Daniel P. Berrange <berrange at redhat.com> - 3.0.3-5.fc6
  - Fixed destroyDevice callers


 b) Improving the hotplug error reporting in XenD
    and the network scripts

  Improve hotplug script error reporting via xenstore.

  Use this to detect and report up-front in vif-bridge script whether
  the bridge device exists or not.

Should be upstream in 3.0.5. Its also patched to Fedora 5/6/7 Xen
RPMs.

So if you run  'xm create'  (or equivalently virsh create) you'll see
a message which looks like:


# xm create XenGuest1
Using config file "/etc/xen/XenGuest1".
Error: Device 51760 (vbd) could not be connected.
Device /dev/HostVG/FC6Root is mounted read-write in the privileged domain,
and so cannot be mounted read-only by a guest.

Dan.
