[Xen-users] one DomU, 2 IP =>why ? any ideas,

[Stéphane Cesbron <Stephane.Cesbron@xxxxxxxxx>]

Hi,

I needed to switch one DomU from one IP to an other tonight.
I'm on centos 5.2 (Dom0 and DomU)
Therefore, I made a script using perl to make so. This script modify the 
IPADDR line in the following files :
- /etc/sysconfig/network-scripts/ifcfg-eth0
- /etc/sysconfig/networking/devices/ifcfg-eth0
- /etc/sysconfig/networking/profiles/default/ifcfg-eth0
Then I reboot the VM and it worked just fine. The VM was still reachable 
using its old ip address. I thought that was because I do not to have 
rebooted the Dom0.
I put my IP back in the above files and rebooted the Dom0 and DomU.
Nevertheless, my DomU is still reachable from the 2 different IPs.

Any ideas/suggestions ?
I can't understand how it is possible. I tried to change the vif mac 
address but it is still the same.
Regards,
