Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.

The daemonizing code lets the parent exit almost immediately. This means that it may think it has successfully started even when important failures occur like not being able to acquire the PID file. It also means network sockets are not yet open. To address this when daemonizing the parent passes an open pipe file descriptor to the child. The child does its basic initialization and then writes a status code to the pipe indicating either success, or failure. This ensures that when daemonizing, the parent does not exit until the pidfile is acquired & basic network sockets are open. Initialization of the libvirt drivers is still done asynchronously since this may take a very long time. * daemon/libvirtd.c: Force parent to stay around until basic config file, pidfile & network socket init is completed |

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.
