 As long as it brings up the serial console, that should be
 sufficient, but working VNC to text console login would be
 convenient. The main thing I want to find on it is the
 BAR mapping addresses from lspci and compare that to the
 e820 map from dmesg.

 I wouldn't expect the memory map provided by SeaBIOS and
 the BAR mappings configured by qemu-dm to differ
 depending on the domU OS. Or am I wrong here?

 If there is any overlap, the problem should be obvious.
 If there is no overlap, then something even more
 bizzare is going on, but we can worry about that
 later. :)
