Hi All,
The change that removes auto-provision of huge pages has been merged into the master branch.
A new provisioning step is required prior to unlocking an AIO controller or a worker node,
if vswitch_type is set to OVS-DPDK.
Configure vSwitch memory per NUMA node:
system host-memory-modify -f <function> -1G <1G hugepages number> <hostname or id> <processor>
i.e. system host-memory-modify -f vswitch -1G 1 compute-0 0
If you plan to create VMs using the huge pages, you would need to configure VM huge pages as well.
Please make any necessary documentation changes.
Regards,
Tao

Hi All,
The changes to support single huge page size have been merged into master.
In this first update, the auto-provision of VM huge pages has been changed from 2M to 1G.
A subsequent update, will remove the auto-provisioning of huge pages for both VM
and vSwitch.
If any test case is dependent on the default VM huge pages, a new step will be required to allocate huge pages for VM on a openstack worker node.
Prior to unlocking a worker node , user provisioning of the vSwitch memory would be required, if vswitch_type is set to OVS-DPDK.

Subject: Pending: Support single huge page size for openstack worker node
Hi All,
Per story
2006295, we are in the process of supporting single huge page size for openstack worker node. This means we will enforce the provisioning of a single huge page size
per worker, which aligns with the non-openstack worker behavior. The automated test cases that attempt to allocate both 2M and 1G huge pages on a worker node should be updated.
The code changes are available here:
