We have gone through one of the most important features provided by a Proxmox cluster. Under HA protection, the VMs are supposed to be online until there is not enough quorum in a cluster. At this stage, I would like to test the cluster functionality first by relocating the VM from one node to another.
As a starting point, we need to ensure that the VM can be started up in both the Proxmox nodes. As the VM is HA-protected, we cannot use
vzctl start for OpenVZ containers and

clusvcadm with the
-e option in the following format:
root@vmsrv01# clusvcadm -e pvevm:<VMID>
In this command,
pvevm is used as a prefix to indicate that it is ...
