According to this post
https://lists.fedoraproject.org/pipermail/xen/2012-August/005879.html
it is a kernel issue. Reassigning ....
Comment 2 Konrad Rzeszutek Wilk 2012-10-02 14:11:29 UTC 
Actually it is a Fedora kernel issue. The kernel (starting from v3.6) should have the patch removed.

The patch in question that should be ditched is: fix_xen_guest_on_old_EC2.patch

We already ditched that across all branches.
