Someone else pointed to the problem - they had had the same problem with
a straight DVD install where the drive order was automatically changed
for some reason: indeed you were on the right track, the kernel line in
the boot menu had the wrong device name when I switched from a non
virtual boot (the emergency boot line was OK?!), using the UUID of the
drive partition instead fixed the problem.

Thanks!

Phil.
