Re: [Xen-users] XCP Question

[Casey DeLorme <cdelorme@xxxxxxxxx>]

I am not having any problems configuring the machines, the toolstack makes plenty of sense. ÂThe only problem I am facing is connecting a console to a running VM. ÂFor me the only gain of using XenCenter is that it would handle that connection. ÂI am quite sure that it won't provide me the information I need to connect to a VM without it, especially not for another platform like Linux or OS X (since XenCenter is a Windows application).

I had spent a good number of hours on Google, and I had read that it was locked down, and was hoping there was a way to unlock it. ÂI had read a guide for an older XCP version that mentioned modifying the listening address in a file in the /opt/xensource path, but after making that change and rebooting connections still did not work.

The XCP platform installed without a GUI environment so connecting from localhost would involve adding a large number of software packages. ÂI was hoping for another solution before I clobber the current environment trying to get Gnome or another Desktop Environment installed and running.

I had read posts about the VNC being locked down, but I was hoping it was just a simple matter of adjusting a setting on the machine, such as changing the listening port. ÂSupposedly older XCP versions allowed this by modifying the VNC configuration file in the /opt/xensource path, but I tried making that change and rebooting to no avail.

I downloaded and have been reading the administration PDF's from Citrix, so I am plenty familiar with the command line options. ÂSadly the term "VNC" only appears twice in that entire document.

Thanks for the suggestions so far, and please keep me posted if anyone comes across a solution for opening up VNC to the outside.

Many XCP folks hang out on the (badly named) xen-api@ list.

The VNC server only listens on localhost for security reasons.

http://wiki.xen.org/wiki/Xen_Cloud_Platform:_Access_to_VM_console
(first hit on google for xcp console)

Or you can find a vncproxy utility on the host somewhere (it used to be
under /opt/xenserver/debug or something like that) which will proxy the
vnc connection over the authenticate XenAPI channel.
