[Xen-users] IP configuration for domU ignored

[Pablo Javier Roca Mendez <pablo_javier_roca_mendez@xxxxxxxxxxxxxxx>]

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
