You can initiate the live migration of a virtual machine (VM) to another node by using the Red Hat OpenShift Service on AWS web console or the command line.
You can cancel a live migration by using the web console or the command line. The VM remains on its original node.
You can also initiate and cancel live migration by using the |
You can live migrate a running virtual machine (VM) to a different node in the cluster by using the Red Hat OpenShift Service on AWS web console.
The Migrate action is visible to all users but only cluster administrators can initiate a live migration. |
The VM must be migratable.
If the VM is configured with a host model CPU, the cluster must have an available node that supports the CPU model.
Navigate to Virtualization → VirtualMachines in the web console.
Select Migrate from the Options menu beside a VM.
Click Migrate.
You can initiate the live migration of a running virtual machine (VM) by using the command line to create a VirtualMachineInstanceMigration
object for the VM.
Create a VirtualMachineInstanceMigration
manifest for the VM that you want to migrate:
apiVersion: kubevirt.io/v1
kind: VirtualMachineInstanceMigration
metadata:
name: <migration_name>
spec:
vmiName: <vm_name>
Create the object by running the following command:
$ oc create -f <migration_name>.yaml
The VirtualMachineInstanceMigration
object triggers a live migration of the VM. This object exists in the cluster for as long as the virtual machine instance is running, unless manually deleted.
Obtain the VM status by running the following command:
$ oc describe vmi <vm_name> -n <namespace>
# ...
