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 ___ CentOS-virt mailing list CentOS-virt@centos.org http://lists.centos.org/mailman/listinfo/centos-virt

Further testing allowed me to get a one machine to work after a bare install with simply a #yum install xen so I am obviously now wrong in my assessment. At this point I believe it to be a simple problem in the CentOS/RH package of Xen (Or Xen itself) as I did try a Fedora Core 8 install and the same behavior was now noted: Some machines function before and after, and some don't function after! That just sounds like random testing, if you dont have the specifics on what you consider to be a minimal install along with package lists, you are not going to get anything that is reproduce able as a means to get Xen working with minimal install. My Linux experience is far too new to allow me to troubleshoot through it, but considering the magnitude of machines I have tried I am shocked if this behavior is not exhibited with other people. Well, I suggest you work out how rpm and yum works and how packages are handled. All you are trying to do, my guess is, work out what is the minimal packageset required to get a functional Xen based virt setup in your environment. -- Karanbir Singh : http://www.karan.org/ : [EMAIL PROTECTED] ___ CentOS-virt mailing list CentOS-virt@centos.org http://lists.centos.org/mailman/listinfo/centos-virt

If I perform a minimal install, then #yum install xen xen-kernel, once I reboot I do not have network access to or from the box unless I switch to routed mode. you might want to start with a list of packages that groupinstall will get and the yum install wont get, then work back from there. at the very least you are going to need libvirt and things it needs to run.
