I see that Xen 3.0.3 is now 3.1 actually (Backporting is obviously a good thing but at the risk of confusing things...). I see an errata listed as "network-bridge fails on some machines" which is my issue, I earlier had thought it was an installation issue but I ended up having Xen work in my preferred setup config on a different machine, so my dependency assumption was clearly wrong. The bug was last updated on 2007-11-07, but using yum to install Xen as I always have been does fetch me the versions of the rpm's that this bug report list: xen-3.0.3-41.el5.i386.rpm. Obviously I don't know for sure if this is my issue but when I run the Xen script to stop the bridged network, the server regains network connectivity so I will venture to say it appears related or very similar to me:) Thanks for all the advice on this matter Karanbir, jlc
