[Starlingx-discuss] Cannot allocate a VM - STX2.0-AIO-SX - Error500

[Chris Friesen]

It looks like you don't have any hugepages allocated.  Lock the node, 
then use the dashboard or the CLI (running something like "system 
host-memory-modify controller-0 0 -1G 2" to allocate two 1G hugepages to 
NUMA node 0).  Then unlock the node.

Kubernetes only allows a single size of hugepage, so whatever size we 
use for the OpenStack guests has to match the hugepage size used for 
vswitch (which defaults to 1G but can be changed to 2MB).
