No, it isn't, good that you noticed (bad that I didn't). vram/64 can be (should be - no driver knows how to map it yet unless you changed it) zero but vram/32 should be > 0. How are the bars allocated? is it seabios or something else? if seabios can you enable debugging messages by adding the following to qemu command line (again - this is upstream, I have no idea how it works with xen): -chardev
stdio,id=seabios -device isa-debugcon,iobase=0x402,chardev=seabios
