With all the changes in F11, I'm trying to set up a Windows XP virtual
machine with kvm/qemu. But not joy:

ERROR    Host does not support any virtualization options

but /proc/cpuinfo shows svm (this is AMD).

What am I missing?
is the kvm-amd module loaded?

lsmod | grep kvm should show it.
if not try to load it by doing modprobe kvm-amd

Yes it is:

lsmod | grep kvm
kvm_amd                30940  3
kvm                   153112  1 kvm_amd

The problem was that not enough of the qemu stack was installed. I
had qemu-common, qemu-x86, qemu-system-x86 installed by yum. I'd
assumed they pull in whatever was necessary. Silly me. Installed all
qemu, now I get the new machine box.

  hang on ... so which qemu-related package was missing?  i'm thinking
qemu-user but it would be nice to clarify that.


I don't know. I'd first done yum groupinstall virtualization. As I remember, that only brought in qemu-img. When that didn't work I installed qemu*x86. I may have installed qemu-user also. Finally yum install qemu*. Then it worked.

Any clues on paravirtualization?

To test stuff running paravirt mode you can run a CentOS-5.3 machine under KVM and then use xen in that. Useful for proof of concept, not so much for production, although I have a light duty web server running that way, because I got tired of upgrading.
