Not sure I get it right, you trying to start a domU with a root disk
on a USB drive ?

- is there multiple partitions ?
- are you tring to export the whole disk ?
- are you able to mount the USB drive's partition(s) on dom0 ?

Please attach your domU config you trying to start,
I think you are missing some lines on the oops message (reason to oops).

I cannot reproduce at the moment (tried exporting different lvm devices),
but that could well be USB specific.
I will try to find a USB drive to hook to it.
