4 In the vSphere Web Client, turn on CPU affinity for processors 4, 5, 6, and 7.
Then, you want this virtual machine to run only on node 1.
1 In the vSphere Web Client inventory panel, select the virtual machine and select Edit Settings.
2 Select Options and click Advanced.
3 Click the Configuration Parameters button.
4 In the vSphere Web Client, set memory affinity for the NUMA node to 1.
Completing these two tasks ensures that the virtual machine runs only on NUMA node 1 and, when
possible, allocates memory from the same node.
Associate Virtual Machines with Specified NUMA Nodes
When you associate a NUMA node with a virtual machine to specify NUMA node affinity, you constrain
the set of NUMA nodes on which NUMA can schedule a virtual machine's virtual CPU and memory.
NOTE When you constrain NUMA node affinities, you might interfere with the ability of the ESXi NUMA
scheduler to rebalance virtual machines across NUMA nodes for fairness. Specify NUMA node affinity only
after you consider the rebalancing issues.
Procedure
1 Browse to the cluster in the vSphere Web Client object navigator.
2 Click the Manage tab and click Settings.
3 Under VM Options, click the Edit button.
4 Select the VM Options tab and expand Advanced.
5 Under Configuration Parameters, click the Edit Configuration button.
6 Click Add Row to add a new option.
7 In the Name column, enter numa.nodeAffinity.
8 In the Value column, enter the NUMA nodes where the virtual machine can be scheduled.
Use a comma-separated list for multiple nodes. For example, enter 0,1 to constrain the virtual machine
resource scheduling to NUMA nodes 0 and 1.
9 Click OK.
10 Click OK to close the Edit VM dialog box.
