kvm 76 - open /dev/kvm: No such device or address

[Matias Aguirre <maguirre@matware.com.ar>]

Hi all,

Im using 2.6.26.5 kernel and slackware-current distribution. I was 
compiled the latest 76 version of kvm and when i run kvm i return this 
error:

open /dev/kvm: No such device or address
Could not initialize KVM, will disable KVM support

The module is already loaded:

# lsmod
Module                  Size  Used by
kvm_intel              33984  0
kvm                   116156  1 kvm_intel
nvidia               6886800  26

And my CPU have VM support.

# cat /proc/cpuinfo | grep vmx

And the file permission:

# dir /dev/kvm
crw-rwxr-- 1 root kvm 250, 0 2008-10-07 18:22 /dev/kvm


Any help?

Thanks
