As I mentioned before, we did buy new server hardware to host the VMs. This hew hardware also has the same NUMA node issue.
I initially installed 14.04.2 on those new servers, then when the NUMA issue was there, I thought "what the hey" and installed 15.04 just for fun. The problem was gone -- NUMA nodes were automatically generated and maintained, though it put everything on node 0 and nothing on node 1 (not sure if that is by design?). Anyhow, noticed a lot of issues with the new migration engine that version uses, so I decided to downgrade back to 14.04 and just bite the bullet manually setting my CPU configurations. So whatever extra help you need from me, I am more than happy to spend time doing any tasks you like. Just let me know.
