Comment 6 for bug 455832

I just noticed that if I have the AoE device partitioned (ie, there are /dev/etherd/e2.2 and /dev/etherd/e2.2p1) then try to attach either, libvirt segfaults, regardless of whether it was previously attached or not. Deleting the e2.2p1 partition and creating an ext2 filesystem directly on e2.2 allows the device to attach.
