Using Centos 5.2 with Xen. I'm making a group of nodes behind an LVS load-director to perform computing services. Those nodes are only accessible from the LVS nodes (I'm using LVS NAT mode). Actually it's Xen virtual servers on the physical nodes behind the LVS boxes that I'm mostly concerned with.
When you create a guest with virt-install, there's a vnc param and a vncport param, but setting vncport doesn't seem to cause the vnc console to actually appear on the specified port. The config file written by virt-install in /etc/xen doesn't contain the vnc port information.
How do I control what port the VNC console is presented on?
I need to make these appear at stable port numbers, because to make the systems manageable from outside the LVS, I'm going to create tunnels on the LVS that go to specific system consoles. To set that up obviously the destination ports need to be somehow known, and since they're on different systems, anything other than simply configuring them to be in stable places is going to get complicated and hence unreliable. (The people maintaining the software on the systems behind the LVS won't be the same people in charge of the LVS, and some of them won't even know anything about Linux or Xen, just Windows.)
Yes, I also asked on the Xen list; not sure how much what I see as Xen is actually basic Xen and how much is Centos, and the documentation I'm using to do this is all the Centos stuff so I figured I should ask here.
