Not sure about the KVM issue. |

I am running an i7-980X Extreme Edition using Gentoo 64-bit, mostly |
| 35 |
stable. Kernel is 2.6.36-gentoo-r6, Virtualbox-4.0.0. I run both |
| 36 |
32-bit Win XP and 64-bit Win 7 Professional here with no problems. |
| 37 |
Typically I have 3 or 4 VMs running at the same time. |
| 38 |

Others have suggested BIOS. I didn't have to set anything specific there. |
| 40 |
|
| 41 |
If not BIOS then I'd look at kernel config next. |
