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

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.
