I am curious if it is > an Altix problem or whether you tested Tiger or HP boxes as well? 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...
