+          If OpenGL support is needed (either with SPICE gl enabled or with
+          egl-headless), libvirt is now able to pick the first available DRI
+          device for the job. At the same time, this improvement is also a
+          bugfix as it prevents permission-related issues with regards to our
+          mount namespaces and the default DRI render node's permissions which
+          would normally prevent QEMU from accessing such a device.
