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. :) Gordan
