The hotplug code was not correctly invoking the security driver in error paths. If a hotplug attempt failed, the device would be left with VM permissions applied, rather than restored to the original permissions. Also, a CDROM media that is ejected was not restored to original permissions. Finally there was a bogus call to set hostdev permissions in the hostdev unplug code * qemu/qemu_driver.c: Fix security driver usage in hotplug/unplug
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.
