How to disable Numa on Virtual Machine

To determine if the database server is a NUMA-based system with NUMA enabled, run the following command as root on the database server:
(root) # numactl -H | grep available
available: 8 nodes (0-7)

- or -

(root) # numactl -H | grep available
available: 2 nodes (0-1)
If the number of available nodes is "2 nodes (0-1)" or "8 nodes (0-7)" then NUMA is enabled. If the number of available nodes is "1 nodes (0)" then NUMA is not enabled.
