Nova hugepage support does not include aarch64
Status in OpenStack Compute (nova):
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.
VM should be launched with hugepages and the libvirt xml should have
<page size='2048' unit='KiB' nodeset='0'/>
VM is launched without hugepages.
There are no error logs in nova-scheduler.
