Once a deployment has been fully upgraded to Train, the CONF.workarounds.enable_numa_live_migration config option is no longer necessary. This patch changes the conductor check to only apply if the cell's (cross-cell live migration isn't supported) minimum service version is old. Implements blueprint numa-aware-live-migration Change-Id: If649218db86a04db744990ec0139b4f0b1e79ad6

In deployments older than Train, or in mixed Stein/Train deployments with a
|
|
rolling upgrade in progress, unless :oslo.config:option:`specifically
|
|
enabled <workarounds.enable_numa_live_migration>`, live migration is not
|
|
possible for instances with a NUMA topology when using the libvirt
|
|
driver. A NUMA topology may be specified explicitly or can be added
|
|
implicitly due to the use of CPU pinning or huge pages. Refer to `bug
|
|
#1289064`__ for more information. As of Train, live migration of instances
|
|
with a NUMA topology when using the libvirt driver is fully supported.
