It is purely cosmetic and is not a problem, however if it does bug you it can be solved by installing the bridge-utils package from Fedora 13/14. Hi Joe, this is mentioned in previous comments.

I guess I will have to rotate all three. THANKS! I really appreciate you making such high quality WarGames desktops, but now I can’t decide which one I want. I guess I will have to rotate all three.

This tutorial is very helpful. Following the listed steps, I successfully brings up CentOS 6.2 with Xen dom0.

If you grab the SRPM for the kernel and modify the config for a 32 bit host, it should work. I haven't actually done this - however I'd love to hear how you go. It should work.

If i were to rebuild the kernel, do you think it could work? Well thanks Steven anyway.

I have 6 32bit only xen servers and would like to update to centos6, but need the xen built kernel for PV installs. Thanks again for your efforts.

No problem for me with CentOS 6.2. The only thing not described here, for this specific distro, was the bridge-utils rpm with is not good anymore. I had to use bridge-utils-1.2-9.fc13.x86_64.rpm (from Fedora Core 13), and it works like a charm ! Xen with Ubuntu was a nightmare, it's much more easy with a RHEL6 based distro. Thanks a lot Steve !!! So far, the best tutorial on how to install Xen.

For example, the aggregation of configuration options over several ports is somewhat erratic. Also, this beast absolutely refuses to put VLAN 1 dot1q encapsulated on a trunk, and my hopes to get around that strange limitation through the command line were disappointed: the command "switchport trunk allowed vlan add 1" is rejected with the strange message: "VLAN 1: VLAN was not created by user." Oh well. At least I get an explicit error message instead of strange GUI malfunctions. And even just being able to see the entire configuration as a text file is enormously helpful. Many thanks for that! Very nice, although there are a few infuriatingly unciscoish kinks.
