Re: [Xen-users] Not able to assing static IP to domU

Hi Meghanand

How did you assigned the domU IP address?

First, you need to be sure that the IP address is available and DNS 
registered. For this, talk with the network administrator.
Second, after having a domU working, you must edit the following files:
1 - /etc/sysconfig/network
2 - /etc/sysconfig/network-scripts/ifcfg-eth0

Here's an example:

more /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=hostname.your.domain
GATEWAY=xxx.xxx.xxx.xxx

more /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=static
BROADCAST=xxx.xxx.xxx.xxx
#HWADDR=
IPADDR=123.243.2.1.12
NETMASK=255.255.255.0
ONBOOT=yes

Use the gateway and netmask as in your dom0. Hopefully, during domU 
installation, these values are taken from the dom0. Important, change 
the BOOTPROTO var to static (not dhcp). Also, take care of the Mac 
address (HWADDR var). If you want to use it, do not forget that it must 
match the one in your xen config file.
Reboot machine. And that's it.
