Add support for doing controlled shutdown / reboot in the LXC driver. The default behaviour is to try talking to /dev/initctl inside the container's virtual root (/proc/$INITPID/root). This works with sysvinit or systemd. If that file does not exist then send SIGTERM (for shutdown) or SIGHUP (for reboot). These signals are not any kind of particular standard for shutdown or reboot, just something apps can choose to handle. The new virDomainSendProcessSignal allows for sending custom signals. We might allow the choice of SIGTERM/HUP to be configured for LXC containers via the XML in the future. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
