Public bug reported:
Ubuntu 18.04 LTS + OpenStack Queens
Example flavour:
+----------------------------+--------------------------------------+
| Field | Value |
+----------------------------+--------------------------------------+
| OS-FLV-DISABLED:disabled | False |
| OS-FLV-EXT-DATA:ephemeral | 0 |
| access_project_ids | None |
| disk | 0 |
| id | 9f3946cc-df0c-468a-80a9-808702d9a620 |
| name | 4c-8192m |
| os-flavor-access:is_public | True |
| properties | hw:mem_page_size='large' |
| ram | 8192 |
| rxtx_factor | 1.0 |
| swap | |
| vcpus | 4 |
+----------------------------+--------------------------------------+
*some* instance creation requests fail to start instances due to lack of
available hugepages on the numa node being targeted for the instance
(log data to follow). Workaround to alleviate this symptom has been to
split the flavor across to numa nodes using hw:numa_nodes=2 as an
additional property, which means the cores for the instance can be split
across the numa nodes on the hypervisor. This does have a performance
overhead.
