Infrastructure Software

Hi guys,

we have some OVM Servers 2.2.1 installed. They all have three NICs in them (eth0-2). For eth0 and eth2 we need multiple IP-Adresses configured to work with our storage solution. The configuration should look like this:

eth0:0 - 192.168.31.x
eth0:1 - 192.168.33.x
eth1 - 192.168.0.x
eth2:0 - 192.168.32.x
eth2:1 - 192.168.34.x

I tried creating gonfig files ifcfg-eth0:0 in /etc/sysconfig/network-scripts with the following content

DEVICE=eth0:0
BOOTPROTO=static
ONBOOT=yes
NETMASK=255.255.255.0
IPADDR=192.168.31.3
TYPE=Ethernet
HWADDR=00:1b:21:06:f0:fa

But it does not work. Neither eth0:0 nore an additional xenbr is configured when i restart.
I can configure multiple ip addresses for xenbr0 by calling something like "ifconfig xenbr0 192.168.31.x". But these settings get lost as sonn as i reboot the server.
I have already searched google, forums and blogs for a solution but could not find one. I thought that this should be a pretty common task. In "normal" linux it is not an issue at all.

Has somebody any experience with a setup like this? I would really apreciate your help.

Thanks
Marek
