No KVM on a XEON E5620

I did a fresh install of debian5/proxmox on a Fujitsu TX200 w. Xeon E5620 and found KVM is gone (on the previous install everything was fine):

open /dev/kvm: Is a directory
Could not initialize KVM, will disable KVM support

I tried kernel 2.6.32 and 2.6.35 with no success.
Here are versions:
proxmox-01:~# pveversion -v
pve-manager: 1.8-18 (pve-manager/1.8/6070)
running kernel: 2.6.35-1-pve
proxmox-ve-2.6.35: 1.8-11
pve-kernel-2.6.32-4-pve: 2.6.32-33
pve-kernel-2.6.35-1-pve: 2.6.35-11
qemu-server: 1.1-30
pve-firmware: 1.0-11
libpve-storage-perl: 1.0-17
vncterm: 0.9-2
vzctl: 3.0.27-1pve1
vzdump: 1.2-13
vzprocps: 2.0.11-2
vzquota: 3.0.11-1
pve-qemu-kvm: 0.14.1-1
ksm-control-daemon: 1.0-6

Of course i checked BIOS, VT is enabled.
What did I do wrong this time?

Best regards, Holger

Hi Tom,

no bios update on my side. It is a new machine, i test installed debian and proxmox last week and everything was fine, i created vm's and they did run fine with KVM.
Then I decided to do a clean new install from scratch because the machine has to go to customer on friday.
I reformated, installed debian and proxmox and out of nothing there is no KVM any more...

I am really stuck.

Regards Holger

OK, solution is in the message (as usually).

"open /dev/kvm: Is a directory"

I named a lvm-volume group as "kvm" which for obvious reasons should be avoided.
Maybe a little reminder in the wiki would help...

Best regards, Holger

Yes, for sure. If you grant me an editor's login...
