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) =================== -- 2.39.3 Signed-off-by: Michal Privoznik <mprivozn@redhat.com> --- v2 of: https://listman.redhat.com/archives/libvir-list/2023-July/241020.html diff to v2: - Reworded, basically every paragraph, to make them sound more user friendly.
