I don't understand this boot error from the domU:

Why does your domU try to assemble a software RAID at all if..

disk = [ 'file:/vd/domains/xen-etch/disk.img,sda1,w', file:/vd/domains/xen-etch/swap.img,sda2,w' ]

..it only has one block device?

Is this a showstopper for you or does it carry on to boot normally?

Do you have an /etc/mdadm/mdadm.conf in the domU?

Does your domU have mdadm set to run and assemble arrays?

Cheers,
Andy
Is there *ANY* reason to do software RAID, LVM, or other filesystem cuteness in a DomU? Except maybe for configuration testing purposes? Let the Dom0 do the work, I'm quite certain it will be more efficient about it.
