How can i specify multiple ips inside a config file for a domU. Thanks. -- regards, Anand Gupta _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Anyone ? I tried using the following vif = [''mac=AA:00:00:18:98:FB, ip=x.x.x.x, vifname=xen01'', ''mac=AA:00:00:18:98:FD, ip=x.x.x.x, vifname=xen02''] and the above works as well. However it creates another interface inside the domU as eth1. Can''t i assign two ips to the same interface ? Any help would be appreciated.

I have been trying to get any replies on this small query of mine. Will appreciate if someone can help me out here. Using the second interface is causing problems, when i boot my centos domU, the second adapter doesn''t have the ip address. If i manually use ifconfig eth1 and specify the ip, netmask only then it comes up. any help will be appreciated. On 4/15/06, Anand Gupta <xen.mails@gmail.com> wrote:> > Anyone ?

You may try with ip alias feature supported by Linux kernel as follows:
1. specify one network interface in the domainU configuration file
vif = [''mac=AA:00:00:18:98:FB, ip=x.x.x.x, vifname=xen01'']
2. add an alias network interface, e.g. eth0:0. Assumed you work under
RedHat, then create a file named /etc/sysconfig/network-scritps/ifcfg-eth0:0
and configure it with whatever network address as you want.

If I understand you correctly, you can do this but would not do it in your Xen configuration file. The domain file would set up your virtual physical interface but your IP addresses would be set by the configuration files within your domU. I always prefer to use iproute2 to establish multiple IP addresses per physical interface. There is a somewhat dated slideshow about iproute2 in the training section of the ISCS open source network security management project (http://iscs.sourceforge.net) or you can search your distribution for a file named ip-cref.ps. Some distributions still prefer the use of aliases where you would set up something like an ifcfg-eth0:0 file using device O:0 which will bind an alias to physical interface eth0. Hope I understood your question and that this helps. Good luck - John>-- John A.
