[fedora-virt] installing f11 x86_64 inside f11 x86_64 is*cripplingly* slow

All, see my other post on this topic.  I've had exactly the issue that
Robert describes below and I'm pretty sure my config is correct.  What I
just determined is that the problem seems to only occur with Fedora 11 beta
guests.  I've just installed a Fedora 10 -x64 guest and it installed
seemingly just as fast as on physical hardware.

I hope this clue helps.  If needed I can generate whatever config
information is needed for further diagnosis.

Sounds like you are not using KVM even though its loaded....

Can you provide the output of 'virsh capabilities' and  for the guest
in question 'virsh dumpxml GUESTNAME'
