Vmware vcenter migration. The operation is not allowed in the current state .

Despite having DRS enabled on our vmware cluster, we are unable to migrate virtual machines.

Every migration ends with the following error:

The operation is not allowed in the current state .

Thist issue occurs not only when using powercli, but also when manually trying to migrate:

$vm | move-VM -Datastore  $datastore -Destination $vmhost

If you check the host configuration (summary tab),  vmotion state is set as “No”, though  Host license is Enterprise plus.


Step 1: Restart licencse service in vcenter
vcenter:~ # /etc/init.d/vmware-cis-license restart
Stopping VMware CIS License Service...
Stopped VMware CIS License Service.
Starting VMware CIS License Service...
Waiting for VMware CIS License Service..................
running: PID:4108
Step 2: Disconnect and reconnect host.

When a disconnection and reconnection is performed, licence information is read, and vmotion host configuration will be re-enabled.
