Looks like Gentoo has good docs: https://wiki.gentoo.org/wiki/OpenRC/User_services

Now, a client can be just anything - virsh [1]. virt-manager, virt-viewer, ... 1: by default, running just 'virsh' in interactive mode won't connect anywhere. Only after the first command is entered virsh opens a connection. Oh, an running virsh in non-interactive mode causes virsh to connect, run the command and disconnect. Michal
