Control: reassign -1 xen-tools 4.5-1
Reassigning to xen-tools as discussed, full BR quoted below.
@xen-tools: I think this is because xen-tools has used the host
initramfs and hence has inherited some sort of hook script which insists
on the RAID stuff being present, which there isn't in the domU. I'm not
sure if you would consider this a bug in xen-tools or by design. You may
wish to reassign this on to the initramfs generator tool and/or raid
packages providing the hooks.
