I don't really get why we have that retry logic at all.
If libvirtd is running, or systemd autostart is present then
virsh connect should work immediately.  If it autostarts and
no guests are present, then ther's no work todo so it'll be
fast enough.

If it fails something either it is stopped and autostart is
disabled, or it is completely broken.

Either way,  a retry loop looks pointless to me.

IOW, instead of adding a check on libvirtd, just
kill the retry loop.
