Hi Todd,

Do you know where I am to pickup that MAC address for the vif? Is it the MAC of the eth from ifconfig that is already being used for the dom0's connection or something else?

Thanks,
Randy

Hi,

dom0 CentOS 5.6 with updates and Virtualization group installed.
domU CentOS 5.6 install

I have configured a conf file and a kickstart and the install goes well,
however, it seems to be reverting to a dhcp install rather then grabbing the
eth
information I give it. Also, it creates an ifcfg-eth0.bak file with the info
I give it with a different MAC address, not sure how it gets
either. If there is anything you know about this please let me know.

If I remove ifcfg-eth0, mv ifcfg-eth0.bak to ifcfg-eth0 and remove the
HWADDR and do a /etc/init.d/network restart
it works fine with the correct IP.

You need to set a MAC address on the vif line of the domU config (for
example vif=['mac=00:16:3e:aa:aa:aa,bridge=xenbr1']

There was also a but in a centos package (one the package like kudzu
or something that causes this), but I'm not sure if that is what you
are running into in this case.

Thanks,
Todd
