Hi,

I've noted that there's less posts from the AMD guys lately (Wei
Huang, Joerg Roedel, Markus Rechberger), does it means that AMD
decided to stop supporting KVM?

If not, I think this is time for AMD to step in and use Anthony's
tools to provide a regression testing platform the same way Intel
does.

It would be really sad to see AMD CPUS being a second class citizen in KVM...

Just my 2 cents,
Gildas

You're right about AMD status not matched Intel's at the moment.
There was some time it was a bit neglected.
AMD & Qumranet are working actively to fix it.
KVM-51 supports XP & 2003 but has some issues with other OSs.
We will soon solve all of these issues.
There is also work in progress wrt regression testing.
Thanks for the feedback,
Dor.
