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

Updated answer:

==============

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.

Thanks for any other suggestions,

=====================

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.

Many thanks for any advice on this.

try following:

sudo yum groupinstall Virtualization
sudo yum groupinstall Virtualization Platform 
sudo yum groupinstall Virtualization Client
sudo yum groupinstall Virtualization Tools

make sure to reboot after that installation is complete

you can check service is started by issuing following command (it should return service is started)

service libvirtd status

That did not work. All it did was install the virt-viewer. Platform Group doesn't exist. I have updated my answer. –  ant2009 Apr 20 '12 at 17:14
    
updated my answer as well –  alexus Apr 20 '12 at 17:34

There are more packages required than just qemu-kvm.

This will get you what you need.

yum groupinstall Virtualization

Edit:

To answer your question about your CPU and virtualization, run

$ egrep '^flags.*(vmx|svm)' /proc/cpuinfo 

If NOTHING is printed, your system does not support the relevant extensions. You can still use the QEMU/KVM, but the emulator will fall back to software virtualization, which is FAR FAR slower.

You should not have to manually load the kvm kernel module. Just start the libvirt service.

service libvirtd start

Now when you run lsmod | grep kvm, you should see

kvm
kvm_intel

If you don't see both modules, kvm is not installed correctly.

still didn't work. I have updated my answer. Does the Atom N550 support virtualization? –  ant2009 Apr 20 '12 at 17:15
    
thanks for your answer. The Atom N550 doesn't support virtualization extensions. I have noticed that when I start the libvirtd it doesn't automatically load the kvm module. However, I have to load the module myself .i.e modprobe kvm. In your option, does the software virtualization still give better performance than virtualbox? –  ant2009 Apr 20 '12 at 17:43
    
Try to also load kvm_intel with modprobe kvm_intel –  uther Apr 20 '12 at 17:46
    
FATAL: Error inserting kvm_intel (/lib/modules/3.3.2-1.fc16.x86_64/kernel/arch/x86/kvm/kvm-intel.ko): Operation not supported. So I guess its back to virtualbox. –  ant2009 Apr 21 '12 at 4:43

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.
