FYI, I've just testing i686 and x86_64  Fedora 11 guest installs on a 
RHEL5 Xen host and they both work flawlessly out of the box - including
a  sane mouse pointer running in absolute, so no dual-cursor problems,
and installing correect PAE kernels

Possibly due to old 0.5.x libvirtd having crashed & left the network running.
Since you've now upgraded to 0.6.1 libvirt, it is capable of noticing that 
the network is already runniing upon startup. So future crashes will recover
better.
