= Disabling hot plugging for all VMs on a cluster
|
|
|
|
[role="_abstract"]
|
|
If you are a cluster administrator and want to disable hot plugging for an entire cluster, you must modify the `spec.configuration.kubevirtConfiguration.developerConfiguration.maxHotplugRatio` setting in the `HyperConverged` custom resource (CR).
|
|
|
|
.Prerequisites
|
|
|
|
* You have installed the {oc-first}.
|
|
* You have installed the {CNVOperatorDisplayName}.
|
|
|
|
.Procedure
|
|
|
|
. Modify the `HyperConverged` CR and set the `maxHotplugRatio` value to `1.0`:
|
|
+
|
|
[source,yaml]
|
|
----
|
|
apiVersion: hco.kubevirt.io/v1beta1
|
|
kind: HyperConverged
|
|
metadata:
|
|
name: kubevirt-hyperconverged
|
|
namespace: kubevirt-hyperconverged
|
|
spec:
|
|
# ...
|
|
kubevirtConfiguration:
|
|
developerConfiguration:
|
|
maxHotplugRatio: 1.0
|
|
# ...
|
|
----
|
|
|
|
. Apply the changes to the `HyperConverged` CR by running the following command:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc apply -f <filename>.yaml
|
|

|
|
|
|
.Verification
|
|
|
|
. Check that you have configured the `maxHotplugRatio` value correctly, by running the following command:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc get hyperconverged -n openshift-cnv -o jsonpath='{.spec.liveUpdateConfiguration.maxHotplugRatio}'
|
|
----
|
|
+
|
|
If the configuration was successful, the output is the `maxHotplugRatio` value that you set in the previous procedure:
