I am trying to run a Ubuntu VM on Fedora 18 host. Now, my processor supports VT, so I have kvm installed and it's working. I launched the machine (Ubuntu 12.04 LTS) and installed kvm inside it. But it's not working. As I did:

modprobe kvm-intel

inside the VM. It gave me error as "operation not supported". I have enabled the nested parameter of kvm at the host.

#cat /sys/module/kvm_intel/parameters/nested
Y

Still I dont get anything when I run

#egrep 'vmx|svm' /proc/cpuinfo

on my guest.

The module is called kvm_intel. You also need to make sure you're enabling nested in your VM definition. This may help: blog.jebpages.com/archives/ovirt-on-ovirt-nested-kvm-fu. –  jasonbrooks Jul 9 '13 at 15:56
