Comment 6 for bug 71348

IIRC I once managed to also have two DomU's and having the third crash my system, but can't remember how I managed that.

This is my CPU, AFAICS it has HT support, but either I deactivated it in the BIOS or it's not active for other reasons - but haven't changed that ages ago, so IMHO my issue is not HT relatead.

AFAICS the DomU Kernels do not cause the crash - IMHO it does not matter what kind of DomU Linux you start, only the Dom0 Kernel matters. It might even not matter if the DomU is Linux - anybody tested with BSD? (I don't have a current CPU :(, thus no VX support)
