Public bug reported: Description ===========
As described in [1], Hyper-V driver supports NUMA placement policies. But it doesn't support cpu pinning policy[2]. So the host should be excluded in NUMATopologyFilter if the end user try to build a VM with cpu pinning policy.

Install OpenStack with Hyper-V driver (with NUMATopologyFilter set in nova.conf) 2. Try to Build a VM with "cpu_policy=dedicated". Expected & Actual result =============== Expected: No valid host error Actual: <TBD: Unverified. Presumably, it would go into some unexpected error. Now this bug is reported because the bug is expected from the codes in NUMATopologyFilter and official documents> Logs & Configs ============== <TBD: Unverified.
