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.

QMP Capability probing will fail if QEMU cannot bind to the QMP monitor socket in the qemu_driver->libDir directory. That's because the child process is stripped of all capabilities and this directory is chown'ed to the configured QEMU user/group (normally qemu:qemu) by the QEMU driver. To prevent this from happening, the driver startup will now pass the QEMU uid and gid down to the capability probing code. All capability probing invocations of QEMU will be run with the configured QEMU uid instead of libvirtd's. Furter, the pid file handling is moved to libvirt, as QEMU cannot write to the qemu_driver->runDir (root:root). This also means that the libvirt daemonizing must be used.

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.
