This is with kvm-81
I'm getting a kernel panic when I modprobe kvm-amd
It used to work until I had to use the CMOS jumper to boot.
The motherboard is an Asus M3N78 PRO
The CPU is an AMD Phenom 9950 Black Edition
Here are the steps I've already tried:
- Checking that virtualization is enabled in the BIOS
- Updating the BIOS
- Restoring the defaults of the BIOS
- Downgrading the BIOS
- Trying various versions of kvm
- Trying various linux kernel versions
- Trying various vcore settings
- Enabling/Disabling Cool & Quiet and AMD C1E
- Tried a known good kernel and modules combo
- Interrupting the boot process to only have udev as a process, and killing it.
- Not having any other modules loaded
What I plan to try:
- Updating to 2.6.28 and kvm-82
- Tranfering the nvram from an identical motherboard I own to the
problematic one, using /dev/nvram
Here are the traces
