RE: [Xen-users] prequisites to hvm domains on vt cpus

["Petersson, Mats" <Mats.Petersson@xxxxxxx>]

HVM is still new in Xen, so the unstable changesets are going to be
pretty variable as to what works and what's broken. I think it's fair to
say that you need to PICK CAREFULLY to find a really good changeset. 

Check the Xen devel mailing list for test-results to see if there is a
recent changeset that looks more hopefull. 

But certainly here at AMD, we're still fixing things in SVM-code, and
I've only recently fixed some bugs that were in shared HVM-code, and I
don't think those are the last ever bugs to be found. 

ACPI can certainly make things worse, but I think the APIC emulation is
decent right now (although I may be wrong on that). 

What type of domain did you try? Windows, Linux or something else? Did
you have a serial console attached, and if so, did you see anything
printed that may give a clue to what went wrong?
