Public bug reported: Looking at this branch of the NUMA fitting code
https://github.com/openstack/nova/blob/51de439a4d1fe5e17d59d3aac3fd2c49556e641b/nova/virt/libvirt/driver.py#L3738 We do not account for allowed cpus when choosing viable cells for the given instance. meaning we could chose a NUMA cell that has no viable CPUs which we will try to pin to. We need to consider allowed_cpus when calculating viable NUMA cells for the instance. ** Affects: nova Importance: High Status: Confirmed ** Tags: libvirt -- You received this bug notification because you are a member of Yahoo!
