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.

https://bugzilla.redhat.com/show_bug.cgi?id=996543 When starting up a domain, the SELinux labeling is done depending on current configuration. If the labeling fails we check for possible causes, as not all labeling failures are fatal. For example, if the labeled file is on NFS which lacks SELinux support, the file can still be readable to qemu process. These cases are distinguished by the errno code: NFS without SELinux support returns EOPNOTSUPP. However, we were missing one scenario. In case there's a read-only disk on a read-only NFS (and possibly any FS) and the labeling is just optional (not explicitly requested in the XML) there's no need to make the labeling error fatal. In other words, read-only file on read-only NFS can fail to be labeled, but be readable at the same time. Signed-off-by: Michal Privoznik <mprivozn@redhat.com> |

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.
