Re: [libvirt] [PATCH v2 11/19] remote: add systemd socket units for UNIX/TCP sockets

We don't do socket activation of libvirtd, since we need to unconditionally start libvirtd in order to perform autostart. This doesn't mean we can't have systemd socket units. Some use cases will not need libvirt's autostart & are thus free to use activation. Signed-off-by: Daniel P.
