However, I have also noticed that the Kronos Wiki pages does have some errors and suppose needs improvement and rewriting. I have come across a number of errors or bugs while working with Ubuntu Oneiric 11.10 that would be nice if maybe the Kronos page reflected. So I will point out here what I found: These are really Ubuntu 11.10 bugs so not really XCP related, and as it was slightly annoying, it was easy to fix. I also used a fresh install of Ubuntu 11.10 - When using gksudo, you get an error: (gksudo:2081): Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap", This was fixed by running: sudo apt-get install gtk2-engines-pixbuf - When using gedit, you get an error: (gedit:2212): Gtk-WARNING **: Attempting to store changes into `/root/.local/share/... AND (gedit:2212): Gtk-WARNING **: Attempting to set the permissions of `/root/.local/share/... This was fixed by running: sudo mkdir -p /root/.local/share - Since to get Xen to run, one has to setup a bridged network using the bridge-utils. However, the latest release of bridge-utils is that gets installed synaptic is 1.5-2ubuntu1.1 which has a bug in it that once you setup a bridged network in the /etc/network/interfaces and reboot, the network just will not connect. The solution was restore /etc/network/interfaces to its default, remove bridge-utils 1.5-2ubuntu1.1, manually install bridge-utils 1.5-2ubuntu1, redo the /etc/network/interfaces settings, reboot and I was able to go on the net. However, I never fully tested it with xen running and within any DomU. - I guess this is a minor Error on the XCP page, but under the heading Workaround xcp-networkd missing file (Ubuntu), it shows to do: echo "bridge" >> /etc/xcp/network.conf But in Ubuntu, it gives you a permission denied error. Even if you put SUDO in front of echo, it does not work and I guess that is not how you do it anyways. So the solution was simply by running this: sudo sh -c 'echo "bridge" >> /etc/xcp/network.conf' I guess most of these are minor errors, BUT can get a little annoying or frustrating when you are just starting out in Xen, Linux, etc and having to search for hours to find the answer you seek. SO figured I pint these out here and maybe someone will update the wiki pages.

- When using gksudo, you get an error:

(gksudo:2081): Gtk-WARNING **: Unable to locate theme engine in
module_path: “pixmap”,

This was fixed by running:

sudo apt-get install gtk2-engines-pixbuf

- When using gedit, you get an error:

(gedit:2212): Gtk-WARNING **: Attempting to store changes into
`/root/.local/share/… AND
(gedit:2212): Gtk-WARNING **: Attempting to set the permissions of

This was fixed by running:

sudo mkdir -p /root/.local/share

So the solution was simply by running this:

sudo sh -c ‘echo “bridge” >> /etc/xcp/network.conf’

I guess most of these are minor errors, BUT can get a little annoying or frustrating when you are just starting out in Xen, Linux, etc and having to search for hours to find the answer you seek. SO figured I pint these out here and maybe someone will update the wiki pages.
