Then I have just now confirmed that this problem goes
deeper and may be different than what people have been
thinking.

I tried virt-rescue just now on a working VM that uses
partitions vda1-6, ie 3 primary and two extended, where
one extended partition is a swap disk, all others are
ext3 or 4 and the MBR is valid and functioning.

It locks up at exactly the same point. I'm going to just
confirm that the VM in question still works since I had
not run it in a couple weeks. I will get back shortly
with that confirmation.
