I'm just trying to use xenconsole.

Have you tried xl console?

 

I've disabled vnc in the vm by adding other_config:disable_pv_vnc=1, so just trying to connect to the text console.

Why not just use the vnc console at first to get things setup?

 

I've actually started trying to add openxenmanager but had a problem compiling with python, it could not find the gtkvnc module, I chatted to the developer and they said they've never tried compiling/installing it on a dom0 before, only ever from a vm. But that's my "catch 22", I need either openxenmanager/xvp appliance so that I can connect to a (any) vm I've created, but it seems I need a vm in order to compile the tools I need to connect with!!!!

I thought the xvp appliance import would be the solution, but not able to connect with xenconsole as per previous error. Will read those docs right now and see if they shed any light, I'm sure its something simple that I haven't done (haven't done ANY "tweaking" of XCP hosts....), so if anyone has any ideas, they would be very much appreciated!

What are you using to connect to the console?

XCP works a little different from the base Xen hypervisor. I would
recommend to use openxenmanager to connect to the console of the xvp
appliance to get it set up.

Some other information that may be helpful to you:
