I see that libvirt 1.1.0 should now support virtualbox 4.2, but I'm having problems getting it to work in OSX.

I have built it using homebrew, which now has 1.1.0 in its formulae.

The error I get when tying to connect is shown below. Any suggestions for where I should look next?

The error about "Failed to find user record for uid 'NNNNN'" is odd. libvirtd *is* started automatically, and runs as my own userid (brian, id 502). Each time libvirtd times out, and restarts again, it shows a different uid in this error message.

Thanks,

Brian.

If I run libvirtd by itself manually with the -v flag, this is all I get:
