According to several threads, such as mine last month - '[Xen-users]
Working with Fedora 15 & systemd' - and '[Xen-users] Problems
with HVM after upgrade from 4.0.1 to 4.1.1', and a private communication with
t.wagner in '[Xen-users] XEN-4.1.1 and linux kernel 3.0-rc5', and finally
'[Xen-users] Re: Trouble starting HVM domU with Linux 3.0.0 and Xen 4.1.1',

hvm & xen 4.1.x don't mix, either with kernel 3.0.0, or pvops 2.6.32 (which
was working with xen 4.0.2 prior to upgrading from fedora 14 to f15, and xen
4.1. In the last thread mentioned above, the solution was to upgrade to xen
4.2 unstable. My equally effective solution was to downgrade to xen 4.0.2,
since fedora rawhide doesn't have 4.2 yet.

Sorry for the top post - I'm not subscribed, but I thought the summary was
worth posting.
