[Xen-users] How to solve ip conflict in Xen3.4 on CentOS5

[KC LO <kclo2000@xxxxxxxxx>]

Hi,

 

I have install Xen3.4 into CentOS5.  I want to restrict the IP used in DomU Guest in order to solve IP conflict problem.  I search for Internet that I can include the IP address in the VIF setting like

 

vif = [ 'ip=8.8.8.8 , mac=00:16:36:40:10:de , bridge=eth0' ]

 

of the xen client configuration file.

 

However, after include this parameter, the DOMU guest OS can still change the IP address.

 

I have try Xen3.0 in the default package of CentOS5.4.  After I added this parameter, iptables will be updated to include

this rule like

ACCEPT     all  --  8.8.8.8  anywhere            PHYSDEV match --physdev-in vif1.0

 

Why the iptables not include this rule in Xen3.4
