Yes, it's at least suspious.

... and these lines are missing when booting the xen kernel.

Ok, so it looks like /dev/md0 wasn't activated correctly for
some reason, thus lvm didn't find any volume groups there.

I don't think placing the root fs directly in /dev/md0 would
change anything.  You'll get the different error then (rootfs
mount fails).  But the reason most likely is the same: md0
is not (or only half-way) activated ...
