Hi Paul,

FWIW, I've also tried to get Xen running under qvm86 with no success.  
The accelerator module generates an error part-way into the Linux boot 
sequence (right after disk probing).

dmesg shows that shadow faulting the GDT is failing but that's occuring 
a bit before it bails out (according to the timestamps).

I can provide a script that can take a built Xen tree and launchs qemu 
with Xen automatically (you could provide an empty disk since it dies 
long before it mounts the disk).  It's not as simple as just passing a 
-kernel because Xen needs to be booted via multiboot.
