Being quite keen on the concept of virtualisation, I find myself in a
bit of a quandary with F7.
Being one who needs an uptodate kernel (my laptop power does funny
things with older ones) I can't run Xen because the kernels are too
old. Therefore I have QEMU/KVM or Vmware.
Though the F7 documents talk lightly about QEMU being all part of the
Virtual Machine Manager, it isn't really; the resulting systems are
slow, refuse to boot off valid ISO images and have no configuration
options for networking. They don't even use the system CDROM until you
specifically add it after the virtual machine is built. So I use
qemu-kvm on the command line; not that the Fedora documents mention
that option - thank heaven for Google!

from the docs site.
libvirt and associated tools like virsh and virt-manager provide a
neutral interface to all underlying VM technologies they support
including Qemu, KVM and Xen.

They *say* they do, but in actual fact they don't work very well at all.
Try running virsh without Xen and all you get is "error: no valid
connection" when you try to do anything!
virt-manager works after a fashion, but gives errors galore, crashes
and a generated guest won't even boot off a valid .ISO file that
qemu-kvm had no trouble with. Even after using qemu-kvm to install the
guest, virt-manager still won't work properly. The resulting guest
won't connect to the external network, the mouse is terribly sticky,
and the manager refuses to reconnect to a running guest. All-in-all,
it's a bit of bad news if you're not running Xen.

virt-manager work great without Xen, if:
# yum install kvm
All issues go away if Xen is not installed and kvm is installed. I
think its in the doc.
virt-manager ASSUMES the existance of Xen and or kvm. It should
probably install kvm as a dependancy, but not everyone needs qemu-kvm.
Good Luck!
