The cgroups ACL code was only allowing the primary disk image. It is possible to chain images together, so we need to search for backing stores and add them to the ACL too. Since the ACL only handles block devices, we ignore the EINVAL we get from plain files. In addition it was missing code to teardown the cgroup when hot-unplugging a disk * src/qemu/qemu_driver.c: Allow backing stores in cgroup ACLs and add missing teardown code in unplug path
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.
