Linux – virt-manager kvm modules are not available

linux-kvmvirtual machinevirtualization

Fedora 16 latest updates running on a HP Mini 210 with an Intel(R) Atom(TM) CPU N550 @ 1.50GHz.

sudo yum groupinstall Virtualization

Only installed virt-viewer

sudo yum groupinstall Virtualization Platform
Loaded plugins: auto-update-debuginfo, langpacks, presto, refresh-packagekit
Warning: Group virtualization does not have any packages.
Warning: Group Platform does not exist.
No packages in any requested group available to install or update

After trying the above I am still getting the same message.

I have installed the virt-manager. When I try and create a new virtual machine I get the following warning:

KVM is not available. This may mean the KVM package is not installed, or the KVM kernel modules are not loaded. Your virtual machines may perform poorly.

I have installed the following package:

qemu-kvm-0.15.1-4.fc16.x86_66

And loaded the kvm module:

lsmod | grep kvm
kvm                   406993  0

Not sure what package I am expected to install, or what kvm kernel module is not loaded?

Normally I use virtualbox without any problem. But I wanted to try and see if this virt-manager performs better.

Also in my case (Fedora 16 32 bits) I've installed everything ...also I've activated bios visualization vt-x... cpu is compatible .. but the same error (KVM is not available. This may mean the KVM package is not installed,or the KVM kernel modules are not loaded. Your virtual machines may perform poorly.)

Finaly I've executed manualy modprobe kvm_intel and all done.
