Comment 18 for bug 1820378

Just to clarify, guest instances will not have a numa topology by default. They will only get a numa topology if something is specifically requested that requires one (hugepages, cpu pinning, pci devices, etc.)

With the default m1.tiny flavor there is nothing that explicitly requests a numa topology, and so I'm not surprised that the instance doesn't have one.

In the WindRiver labs we generally default to specifying hugepages in the flavor extra-specs and so that's why our instance XML had the numa topology.

From talking with Matt it's not the fact that the instance doesn't have a numa topology that is the source of the problem, but rather the fact that it doesn't have hugepages since apparently OVS-DPDK requires hugepage-backed memory.
