Need to know the exact step by steps to add a new node in our existing Proxmox panel without cluster, so that we can only manage the new node from our Proxmox panel.
Please add this feature.
Or at least send the VM to another node via network?
Don't realy see the Point,
you can install 2 servers (or more)
and then connect them just over the public IP (as a Cluster ... but all nodes still work standalone):

now just set the qorum level deep if you not have 3 or more server...
with "pvecm expected 1" you can set the Qorum requirement to 1, (not tested if possible to set persistent)
Now just go to datacenter and Storage
and recreate the entry for every server by his own if not setup identical.
now you can manage all servers in one window and if you like migrate servers...
