Re: [Xen-users] domU static IP


The problem seems to have been resolved by following the instructions given in comment#3 of the bugzilla discussion below:


Basically, I modified the ifcfg-eth0 file to add a function that reads /proc/cmdline and sets the parameters to eth0 interface. This is fantastic!! Thanks for everyone who responded to my question.

I'm trying to setup xen on a server with bridge networking. I have RedHat as my dom0. I have two Ubuntu instances and one CentOS instance as domU's. All of them (dom0 and domU) use static ip addresses.

The configuration files for domU's specify in the vif line what ip address to be assigned to that particular domU. It works fine for my ubuntu domU's. But it does not work for my CentOS domU.

Can someone help me figure out what's going on? Also, what is the  best way to configure domU with static ip?


I had the same problem. Your CentOS kernel needs to be recompiled...
An update on the website about this:

"The kernel has to be compiled with CONFIG_IP_PNP to enable the
automatic network settings.

Then IP, Netmask, Gateway, … will set from config-file (as long, there
is no extra setting in domU's /etc/network/interfaces for eth0)

grep IP_PNP /boot/config-2.6.-xen" shows you if it is set." - xen mailing list
