= Verifying vNUMA status of a VM
|
|
|
|
[role="_abstract"]
|
|
VM administrators might need to confirm whether non-uniform memory access (NUMA) is configured for a VM, to verify the VM's resource allocation setup for high-performance, latency-sensitive workloads that rely on memory locality.
|
|
|
|
You can verify whether an already deployed VM is configured for vNUMA by checking the `spec.domain.cpu.numa` attribute. This is displayed as a *vNUMA* badge in the {product-title} web console.
|
|
|
|
.Prerequisites
|
|
|
|
* You have access to an {product-title} cluster with {VirtProductName} installed.
|
|
* If you want to use the command line for verification, you must have installed the {oc-first}. Otherwise, you only need access to the {product-title} web console.
|
|
|
|
.Procedure
|
|
|
|
* To verify vNUMA status on the command line, check that the `spec.domain.cpu.numa` attribute is configured by using the {oc-first}. Run the following command:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc get vm <vm_name> -n <namespace> -o jsonpath='{.spec.template.spec.domain.cpu.numa}'
|
|
----
|
|
+
|
|
If any output other than an empty string is returned, vNUMA is enabled for the VM.
|
|
|
|
* To verify vNUMA status in a GUI, check if the VM has a *vNUMA* badge in the {product-title} web console. Go to *VirtualMachines* -> *VirtualMachine details*, and check either the *Overview* or the *Configuration* tabs.
