Not sure about the KVM issue. I am running an i7-980X Extreme Edition using Gentoo 64-bit, mostly stable. Kernel is 2.6.36-gentoo-r6, Virtualbox-4.0.0. I run both 32-bit Win XP and 64-bit Win 7 Professional here with no problems. Typically I have 3 or 4 VMs running at the same time. Others have suggested BIOS. I didn't have to set anything specific there. If not BIOS then I'd look at kernel config next. - Mark
