When I run virt-manager, and click on the icon to create a new virtual machine, I get an error that KVM is not installed or is not loaded.

I use Ubuntu GNOME 14.04

All qemu packages are version 2.0.0+dfsg-2ubuntu1 qemu-kvm and many other qemu packages installed...

libvirt packages: 1.2.2-0ubuntu13.1

libvirt0 libvirt-bin libvirt-doc python-libvirt

virt-manager 0.9.5-1ubuntu3

When I open terminal and enter

lsmod | grep kvm

I get nothing returned. No lines showing kvm or kvm_amd and no error of any kind.

Hardware: Tyan S2877 with dual Opteron 285s I have the latest bios and don't see any setting in there to turn virtualization on or off.

when I run

sudo apt-get -s install qemu-kvm

Here are the results:

The following packages were automatically installed and are no longer required: kde-l10n-engb libgtk2-gladexml-perl libqt4-test libvncserver0 Use 'apt-get autoremove' to remove them. 0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.

@jobin: the problem was my hardware. I just bought it a few months ago, although obviously used LOL
