It's not clear if you're trying to execute instructions such as VMREAD
inside qemu or use qemu's device models + VT-x (used to be called VMX)
for executing instructions.
If it's the latter, the code is in xen-unstable now. Can boot Linux,
FreeBSD, MSDOS etc.
We took a 0.6.1 snapshot and were able to run with very few modifications
to the "hw" directory.
There were some discussions on where qemu should run on xen-devel (Look
for the thread "Device model architecture")
The main changes we did were:
- accelerate i8254 by moving parts into the hypervisor
- We had some hacks to run without the BIOS, but now that we have BIOS
support, these can go away.
In general, we do have a desire to keep the tools/ioemu/hw directory in
Xen insync with the upstream qemu development.
Comments/suggestions?
