[Fedora-xen] Setting up libvirt to work with Xen 3.4.1 on F11

[Boris Derzhavets]

My primary concern is creating HVM guest via virt-manager at Xen 3.4.1 Dom0 on F11.

Boris.
P.S.
Personally, i don't need libvirt at all to create PV and HVM DomUs at any Xen Dom0.
It's client's requirement.

Looks like something wrong/missing in libvirt..

Did you try with the default Xen 3.3.1 version, that is included in F11? 
Maybe something was changed in Xen 3.4 and it causes that problem.

Also, can you create HVM guests using just the Xen tools, not virt* stuff?
