I'm experiencing a similar problem with a debian/etch xen host. Kernel is 2.6.18-6-xen-amd64 with the Steve Kemp's xen-utils-3.1.3-1 backport.

Devices are LVMs partitions from a SAN FC storage.

I've try with various device names, like xvd* but this didn't help. Part of my domU config file is:

root        = '/dev/xvda2 ro'
disk        = [

(xvdb1 is an OCFS2 clustered partition which explains the w!)

Any idea will be greatly appreciated!

Thanks in anticipation.
