First i have public ips for all domUs needed , and i need to use public ips. Is 
there any chance in that way to use nat for only mac?

2nd. Do you think i should go for xen 4 ? Or xen 4 has same problem with route 
and bridge ? 

And finaly , i used PV drivers on 1 centos domU , and it worked , but after 
first restart , its all back to tap interface again , even thou modprobe.conf 
is setup to use pv drivers. 

Tnx for help!
