Currently when launching the LXC controller we first write out the plain, inactive XML configuration, then launch the controller, then replace the file with the live status XML configuration. By good fortune this hasn't caused any problems other than some misleading error messages during failure scenarios. This simplifies the code so it only writes out the XML once and always writes the live status XML. To do this we need to handshake with the child process, to make execution pause just before exec() so we can write the XML status with the child PID present.
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.
