Hi all,
I have create a centos in domU using "xm create test.cfg". The
content of test.cfg print as below:
kernel = "/usr/lib/xen/boot/hvmloader"
builder = ''hvm''
name = "test"
memory = 512
disk = [
''file:/root/xen/ubuntu-9.10-desktop-i386.iso,hdc:cdrom,r'',
''file:/srv/xen/mailserver.img,hda,w'' ]
boot = "d"
vif = [''ip=192.168.1.100,bridge=eth1'']
dhcp = "off"
vcpus=1
on_reboot = ''restart''
on_crash = ''restart''
sdl=0
vnc=1
vnclisten="0.0.0.0"
vncpasswd=''password''
stdvga=0
serial=''pty''
usbdevice=''tablet''
I set static ip==192.168.1.100 in vif, but the centos in domU still
use the dhcp. To be noted here, I can set static ip in centos when I
connect to the console of domU.
Who can tell me why and how to set static ip in config file.
Thanks a lot.
Best Wishes!
Qiang Ma

There are cases when setting IP in domU config file can be used (for example when deploying custom bridge+iptables script), but that''s kinda complicated. The short version is that using the default setup the setting is not used and has no effect on actual domU IP address. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
hi, Thanks very much. I have many VMs to deploy and have to set static ip for each VM. So I want to try some methods. Can you send me some cases such as deploying custom bridge+iptables script?

It will if you recompile the kernel or use a different OS like Debian in the DomU. The CentOS kernel does pay attention to the MAC address assigned in the DomU config file though so you can set up a DHCP server with that MAC in it and it will assign the IP you want.
