Hi all,

I have enabled Virtualization in BIOS. However, when I  modprobe
kvm-intel, I get $ sudo modprobe kvm-intel
FATAL: Error inserting kvm_intel
(/lib/modules/2.6.35+/kernel/arch/x86/kvm/kvm-intel.ko): Operation not
supported

And $ dmesg | grep kvm
[  220.670287] kvm: disabled by bios

egrep '(vmx|svm)' /proc/cpuinfo
