[libvirt] [PATCH 0/3] Improve flexibility of SELinux labelling

This patch series adds two new features - The ability to override 'system_u:system_r:svirt_t:s0' from /etc/selinux/targeted/contexts/virtual_domain_context using the guest XML - The ability to use dynamic relabelling of resources, in combo with static VM label assignment. The latter is useful for management applications which want to be in full control of assigning VM labels (so that they can be unique across an entire cluster of hosts for example), while still benefiting from automatic relabelling of resources in the XML.
