I don't know if this has been reported or not but the bug here:

https://bugzilla.redhat.com/show_bug.cgi?id=465643

Appears under both kqemu and KVM.  I tried this with --no-kvm on kvm-77 and saw this issue.  These tests would indicate that this issue is in the common Qemu code.

Is anyone aware of the issue?
