Proxmox: Use external VNC without inetd

Alex Harris on his blog gives a method for using external VNC viewer by modifying the VM configuration file as opposed to the INETD configuration which is what I typically see. Note: I have not yet tested this to ensure it works.

... go to the /etc/pve/nodes/proxmox/qemu-server directory. In the 1##.conf file (where 1## is the id of the VM), put the following lines:
args: -vnc 0.0.0.0:10
You can do this with each vm, just make sure the change the number after the last colon, as
each vnc connection has to be on it's own port. Then you can vnc using your favorite vnc viewer, and use the ip address/hostname of the proxmox server followed by a : and the number that's at the end of the line you put in the VM's config file. In this case it would be "vncviewer proxmox-machine:10"
