Exporting a whole device still causes a hang, but file: works for me now.
works:
disk =3D [ 'file:/usr/src/xen-unstable.hg.tot/testing/newfs.00.vbd,hda1,w' = ]

hangs:
disk =3D [ 'file:/usr/src/xen-unstable.hg.tot/testing/newfs.00.vbd,hda,w' ]=

Did you set /proc/sys/kernel/hotplug to the hotplug executable?

This is centos4.1 so it is enabled by default.

-bash-3.00# cat /proc/sys/kernel/hotplug
/sbin/hotplug

 

Also what is Aruns workaround? There is no email from Ar= un in this thread.

He sent out e-mail on August  24th when he had similar problems with t= imeouts.
