Re: [PATCH v2 20/22] admin: add 'daemon-shutdown' command

The daemons are wired up to shutdown in responsible to UNIX process signals, as well as in response to login1 dbus signals, or loss of desktop session. The latter two options can optionally preserve state (ie running VMs). In non-systemd environments, as well as for testing, it would be useful to have a way to trigger shutdown with state preservation more directly. Thus a new admin protocol API is introduced virAdmConnectDaemonShutdown which will trigger a daemon shutdown, and preserve running VMs if the VIR_DAEMON_SHUTDOWN_PRESERVE flag is set. It has a corresponding 'virt-admin daemon-shutdown [--preserve]' command binding. Signed-off-by: Daniel P.
