This is now fixed and the test suite works even with the + latest version of musl. + + * conf: Introduce ``
`` for virtio-mem and virtio-pmem + + To ensure guest ABI stability, libvirt persists address for memory devices, + now including ``virtio-mem`` and ``virtio-pmem``. The address can be also + specified by user. + * **Bug fixes** + * qemu: Account for NVMe disks when calculating memlock limit on hotplug + + When no ```` is set, libvirt still tries to guess a sensible + limit for memlock for domains. But this limit was not calculated properly + on a hotplug of ````. + + * numa: Deny other memory modes than ``restrictive``` if a memnode is ``restrictive`` + + Due to a missing check it was possible to define a domain with incorrect + ````. For instance it was possible to have a ```` and ```` of a different mode. This is now + forbidden and if either all ````-s and ```` have to have + ``restrictive`` mode, or none. + + * qemu: Start emulator thread with more generous ``cpuset.mems`` + + To ensure memory is allocated only from configured NUMA nodes, libvirt sets + up cpuset CGgroup controller, even before QEMU is executed. But this may + prevent QEMU from setting affinity of threads that allocate memory. Since + these threads are spawned from the emulator thread, the initial set up must + be more generous and include union of all host NUMA nodes that are allowed + in the domain definition. Once QEMU has allocated all its memory, the + emulator thread is restricted further, as it otherwise would be. + v9.3.0 (2023-05-02) ===================
