libvirt-bin error on a VM when I try to list VM

Your installation of libvirtd needs to be configured to handle the vbox+ssh connection type. Details on how to do this are covered here, titled: VirtualBox hypervisor driver.

There's a sample domain XML config that you'll need to load into libvirtd so that it knows how to talk to the VirtualBox VM.

Save this to a file, say my.xml, on your system and then use virsh to import it.

$ virsh create my.xml

NOTE: You'll also need the libvirt daemon driver installed. On Fedora 20 it's in a package called: libvirt-daemon-driver-vbox. You'll need libvirt-daemon along with the interface, libvirt-daemon-driver-interface. I would assume there are similar packages that provide these on ArchLinux.
