Thanks for proposing to add aarch64 support to hugepages and NUMA instances.
Considering the operator impact and the fact that we would need to verify the libvirt and qemu minimum versions that we ship for making sure they support the above, I think it is really important to have that specific feature request to be handled accordingly with people able to review your proposal. In Nova, we follow a specific process for writing new specifications and proposals that you can find more information on http://docs.openstack.org/developer/nova/process.html#how-do-i-get-my- code-merged Basically, it requires you to write a blueprint and discuss on IRC to see whether your blueprint needs a formal specification writing called a "spec" file. ** Changed in: nova Status: In Progress => Invalid -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1623871 Title: Nova hugepage support does not include aarch64 Status in OpenStack Compute (nova): Invalid Bug description: Although aarch64 supports spawning a vm with hugepages, in nova code, the libvirt driver considers only x86_64 and I686. Both for NUMA and Hugepage support, AARCH64 needs to be added. Due to this bug, vm can not be launched with hugepage using OpenStack on aarch64 servers. Steps to reproduce: On an openstack environment running on aarch64: 1. Configure compute to use hugepages. 2. Set mem_page_size="2048" for a flavor 3. Launch a VM using the above flavor. Expected result: VM should be launched with hugepages and the libvirt xml should have <memoryBacking> <hugepages> <page size='2048' unit='KiB' nodeset='0'/> </hugepages> </memoryBacking> Actual result: VM is launched without hugepages. There are no error logs in nova-scheduler.
