I found a couple of bugs but my kernel is updated https://bugzilla.kernel.org/show_bug.cgi?id=42829
I tried to configure Openvswitch and neither, I have the same issue.

Hi: Several questions: - Can you reproduce the issue for refent qemu-kvm/kernel? - What's the qemu cli or libvirt XML for launching guest? Thanks
