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= , 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  --  anywhere            PHYSDEV match --physdev-in vif1.0
Why the iptables not include this rule in Xen3.4
