The virtual machine status is unknown and cannot be operated. How do I resolve this?

Cause

The host is in an abnormal state, preventing virtual machine operations through the virtualization platform UI.

Solution

1. Check whether the host running the virtual machine is in a disconnected state.

2. Log in to the Management Node and run the following commands to stop the virtual machine:

   [root@localhost ~]# zstack-cli
   admin >>> LogInByAccount accountName=admin password=$password  //admin password
   admin >>>  UpdateVmInstance state=Stopped uuid=$UUID  //UUID of the target virtual machine

3. Restart the virtual machine from the virtualization platform UI.
