Public bug reported:

Env:
host with 2 numa nodes.

flavor n2 request two instance numa nodes
flavor n3 request three instance numa nodes

Reproduce:
Boot an instance with flavor n2, which scheduled to the host.
Resize the instance with n3.

As above, the scheduler only see two instance numa nodes. It means the new flavor extra specs weren't parsed.

The host only has two numa nodes, but the request resizing to three
instance numa node still schedule to the host. And the move claim
refused the request.

Expect:
The request of instance numa nodes should be updated with new flavor. And the scheduling should make a right scheduling in the beginning.

Title:
  The new flavor extra specs weren't parsed when resize

Status in OpenStack Compute (nova):
  Confirmed

Bug description:
  Env:
  host with 2 numa nodes.

  flavor n2 request two instance numa nodes
  flavor n3 request three instance numa nodes

  Reproduce:
  Boot an instance with flavor n2, which scheduled to the host.
  Resize the instance with n3.

  Nov 28 18:27:18 jfz1r03h15 nova-compute[52929]: ERROR oslo_messaging.rpc.server ComputeResourcesUnavailable: Insufficient compute resources: Requested instance NUMA topology cannot fit the given host NUMA topology.

  The host only has two numa nodes, but the request resizing to three
  instance numa node still schedule to the host. And the move claim
  refused the request.

  Expect:
  The request of instance numa nodes should be updated with new flavor. And the scheduling should make a right scheduling in the beginning.
