ESX Server provides two sets of controls for NUMA placement, so that
administrators can control memory and processor placement of a virtual
machine.
Figure 2-4 Setting CPU or memory affinity on VMware ESX 3.0.x / 3.5.x in VI Client or Virtualcenter
The VI Client allows you to specify:
CPU affinity: A virtual machine should use only the processors on a given
node.
Memory affinity: The server should allocate memory only on the specified
node.
If both options are set before a virtual machine starts, the virtual machine runs
only on the selected node and all of its memory is allocated locally.
An administrator can also manually move a virtual machine to another node after
the virtual machine has started running. In this case, the page migration rate of
the virtual machine should also be set manually, so that memory from the virtual
machine's previous node can be moved to its new node.
