Monitoring live migration of a virtual machine instance
You can monitor the progress of a live migration of a virtual machine instance from either the web console or the cli.
Monitoring live migration of a virtual machine instance in the web console
For the duration of the migration, the virtual machine has a status of Migrating. This status is displayed in the Virtual Machines list or in the Virtual Machine Details screen for the migrating virtual machine.
Procedure
-
In the container-native virtualization console, click Workloads → Virtual Machines.
Monitoring live migration of a virtual machine instance in the cli
The status of the virtual machine migration is stored in the Status component
of the VirtualMachineInstance configuration.
Procedure
-
Use the
oc describecommand on the migrating virtual machine instance:... Status: Conditions: Last Probe Time: <nil> Last Transition Time: <nil> Status: True Type: LiveMigratable Migration Method: LiveMigration Migration State: Completed: true End Timestamp: 2018-12-24T06:19:42Z Migration UID: d78c8962-0743-11e9-a540-fa163e0c69f1 Source Node: node2.example.com Start Timestamp: 2018-12-24T06:19:35Z Target Node: node1.example.com Target Node Address: 10.9.0.18:43891 Target Node Domain Detected: true
