While porting the code to FUSE3 this area was + reworked and the file can now be read with any granularity. + + * qemu: Be less aggressive around cgroup_device_acl + + A basic set of devices common to every domain can be set in ``qemu.conf`` + via cgroup_device_acl knob. Devices from this set are allowed in CGroup and + created in domain private namespace for every domain. However, upon device + hotunplug it may have had happened that libvirt mistakenly denied a device + from this set and/or removed it from the namespace. For instance, + /dev/urandom was removed and denied in CGroup on RNG hotunplug. + + * nodedev: trigger mdev device definition update on udev add and remove + + When nodedev objects are added and removed mdev device definitions are + updated to report correct associated parent. + v8.1.0 (2022-03-01) =================== -- 2.35.1
