[libvirt-users] libvirt, OSX and VirtualBox - how?

I have a new OSX Lion Macbook and would like to control VirtualBox using
"virsh" (as I do with KVM under Ubuntu).
I've got this far:
* Installed VirtualBox
* Installed libvirt (brew install libvirt)
But now I'm a bit stuck :-)
I ran VirtualBox itself, and created a test VM successfully.
If I try to use virsh, this is what I get:
Brians-MacBook-Air:~ $ virsh -c vbox:///session
error: internal error unable to initialize VirtualBox driver API
error: failed to connect to the hypervisor
Brians-MacBook-Air:~ $ virsh -c vbox+unix:///session
error: Failed to connect socket to '@/Users/brian/.libvirt/libvirt-sock': No such file or directory
error: failed to connect to the hypervisor
If I try to start libvirtd, this is what I get:
Brians-MacBook-Air:~ $ /usr/local/sbin/libvirtd
00:00:18.970: -1: info : libvirt version: 0.9.6
00:00:18.970: -1: error : virNetSocketNewListenUNIX:340 : Failed to bind socket to '@/Users/brian/.libvirt/libvirt-sock': No such file or directory
[but directory /Users/brian/.libvirt was created]
However, VirtualBox itself is running OK:
Brians-MacBook-Air:~ $ VBoxManage list vms
"test" {d0d74c25-1dfc-44a4-8a2b-1d25b7972e7c}
Furthermore, dtruss suggests that virsh is finding the installed VirtualBox:
Brians-MacBook-Air:~ $ sudo dtruss -f virsh -c vbox:///session 2>&1 | grep -i virtualbox
error: internal error unable to initialize VirtualBox driver API

But looking at the dtruss output shortly before it prints the error message
doesn't give me any clues as to what's going wrong.

Has anybody got libvirt + OSX Lion + VirtualBox working, and if so, how did
you do it?
I see the same question asked here:
http://stackoverflow.com/questions/7946994/libvirt-and-virtualbox-on-osx
but unfortunately no response as yet.
Thanks in advance,
Brian.
