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.

Comment 3 Konrad Rzeszutek Wilk 2012-10-02 14:12:12 UTC
The patch in question that should be ditched is: fix_xen_guest_on_old_EC2.patch

We already ditched that across all branches.

Michael,

Can you please update your kernel?

Comment 6 W. Michael Petullo 2012-10-04 03:20:43 UTC
Seems fixed in kernel-3.5.4-2.fc17.x86_64.
