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 _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
