When a disk is hot-plugged to a virtual machine (VM) using virtctl without the --persist flag, a warning message is displayed indicating that the added disk is persistent even though it is not.
Moreover this warning is misleading and unnecessary, as hot-plugging disks should not require a VM restart. Therefore there should not be any warning in the first place to restart the vm

Prerequisites: You must have at least one data volume or persistent volume claim (PVC) available for hot plugging.

1.  virtctl addvolume <virtual-machine|virtual-machine-instance> \
  --volume-name=<datavolume|PVC> 

Check screenshot for reference

The warning message should not appear when hot-plugging disks to a VM. The disks should be added successfully without any indication of persistence or warning for the need of the VM restart.

The disks are added successfully, issue is the incorrect warning.
