It's been on an HP blade with two Montecito CPUs (8 logical), but I
wouldn't call that "testing".  The goal of my effort has been to get KVM
on Itanium compiled and packaged for a first time (based on kvm-74).
That a VM started to boot at all, with 4 CPUs and 4 GB, was almost
"good enough"(TM) for me.  Alas, stability was very poor, so I went
down to 2/2 (or so), which allowed me to install SLES11-Alpha2.
But even that "froze" occasionally, so  I resorted to 1/2 and had
a mostly idle VM survive several days...

IOW, yes I can confirm, that my snapshot of KVM had stability issues
on non-Altix hardware!

Unfortunately there's no time left for keeping up with upstream development
and further testing at this time...

Thanks,
