I installed xen 3.4.1 & M.young's xendom0 kernel on fedora 12 beta. Everying works smoothly for me except that I can't use "tap:aio" for PV guest. It seems that blktap driver is not installed (not supported) on dom0 kernel.
I think performance of guest OS is better when is mounted by blktap. Is there anyway I can use this option?

unfortunately blktap2 is not yet available for pvops dom0. So atm you should use phy: and lvm-volumes.
If you know C and linux kernel coding you could help with porting the blktap2 driver from 2.6.18 to pv_ops dom0 2.6.31.x :)
