Hmm, works for me on a quick smoke test.  Do you remember what exactly
broke and which version it was?  Maybe the 1.7.2 -> 1.7.5 update fixed
it?

Or was it live-migration by chance?  rhel6 qemu doesn't emulate pam
registers correctly, and seabios has a workaround for that.  So
live-migrating between versions with and without correct pam emulation
creates some *ahem* very interesting corner cases ...

cheers,
