Thanks for the link Tim!
Right now, I have two things I'm unsure about...
One is that I had 1945 huge pages left (of size 2048k) and tried to create a VM
with a small flavor (2GB), which should need 1024 pages, but Nova indicated that
it wasn't able to find a host (and QEMU reported an allocation issue).
The other is that VMs are not being evenly distributed on my two NUMA nodes, and
instead, are getting created all on one NUMA node. Not sure if that is expected
(and setting mem_page_size to 2048 is the proper way).
Just in case you haven't figured out the problem...
Have you checked the per-host-numa-node 2MB huge page availability on your host?
If it's uneven then that might explain what you're seeing.
