Re: [Xen-users] IP configuration for domU ignored

Hi!

I have the same problem! Any issues?

My configuration file is :

name="vm01"
kernel="/boot/vmlinuz-2.6.16-xen"
root="/dev/hda1"
memory=17
disk=['file:/vserver/images/vm01.img,hda1,w','file:/vserver/images/ vm01-swap.img,hda2,w']
# network
vif=[ '' ]
dhcp="off"
ip="192.168.1.11"
netmask="255.255.255.0"
gateway="192.168.1.1"
hostname="vm01"

extra="3"

When domU run the ip, hostname, ... aren't configured automatically with the conf file. I haven't this problem with xen3.0.1.

My workstation configuration :

512 RAM
Intel Mobile technologie
Debian Sarge 3.1

Hello everybody,

short update on my issue:

I removed the Xen 3.0.2 packages (from Opensuse 10.1) and installed from xen-3.0.1-install-x86_32.tgz; now the configuration options regarding IP
address and hostname are not ignored.

Does anyone know why they are being ignored in the latest stable version?

It also happens when installing xen-3.0.2-install-x86_32.tgz on Kubuntu 5.10,
so it is not a problem with the packages in opensuse 10.1

Regards,
Pablo

Hello!

I have a problem with Xen 3.0.2 (xen-3.0.2_09656-4) on Opensuse 10.1 regarding setting the IP address for the domU in the configuration file: the settings
are just ignored.
This problem doesn't happen when using Xen 2.0.7 (same image file, same
configuration options).

This are my configuration options for domU:

kernel = "/work/xen/vmlinuz-2.6.16-xen"
#cpu = -1   # leave to Xen to pick
memory = 128
disk = ['file:///work/xen/knscsl021-vm3.sda,sda1,w']
name = "knscsl021-vm3-domain"
dhcp="off"
#vif=[ '' ]
vif = [ 'mac=aa:16:3E:aa:aa:cc, ip=172.28.77.99' ]
hostname = "knscsl021-vm3"
ip = "172.28.77.99"
network = "172.28.77.0"
netmask = "255.255.255.0"
gateway = "172.28.77.1"
root = "/dev/sda1 ro"
extra = "3"
restart = 'onreboot'

It doesn't matter what configuration options I choose for hostname or ip, they
are ignored (i.e. the configuration in domU in ifcfg-eth0 is used)

The only difference I see between Xen3 and Xen2 is in the kernel commmand line:
- For Xen 3:
Kernel command line: ip=172.28.77.99::172.28.77.1:255.255.255.0:knscsl021-vm3:eth0:off root=/dev/sda1 ro 3
- For Xen 2:
Kernel command line: ip=172.28.77.99:1.2.3.4:172.28.77.1:255.255.255.0:knscsl021- vm3:eth0:off root=/dev/sda1 ro 3

I know that setting the correct IP address in ifcfg-eth0 in domU works, but that isn't a solution for me. The ideal solution would be that domU uses the IP provided in the domU configuration file, but I can't understand why it works
for Xen 2.7.0 but not for Xen 3.0.2. Does anybody have any ideas?


Thanks in advance.
Regards,
Pablo
