As expected. You can't paint a traffic light green and expect not to crash ;)

I don't know how the bios of this particular proliant model is setup, but
an all recent x86 platforms i've seen so long, there is the need of turning
on svm (amd) or vmx (intel) at the bios. I've never had problems with
supermicro or tyan, but there have been discussions on the list which
generally shows that if there's no bios option, there's no svm/vmx at all.
