The libvirt sanlock plugin is intentionally leaking a file descriptor to QEMU. To enable QEMU to use this FD under SELinux, it must be labelled correctly. We dont want to use the svirt_image_t for this, since QEMU must not be allowed to actually use the FD. So instead we label it with svirt_t using virSecurityManagerSetProcessFDLabel * src/locking/domain_lock.c, src/locking/domain_lock.h, src/locking/lock_driver.h, src/locking/lock_driver_nop.c, src/locking/lock_driver_sanlock.c, src/locking/lock_manager.c, src/locking/lock_manager.h: Optionally pass an FD back to the hypervisor for security driver labelling * src/qemu/qemu_process.c: label the lock manager plugin FD with the process label
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.
