Basic networking using a separate physical nic for guest traffic

[Luke Camilleri]

Hi there, can anyone help me in configuring a second physical nic for 
the guest traffic please?

I am using the basic networking model and would like to use a dedicated 
nic to handle the guest traffic. i have set a network label (CS-GUEST) 
in xenserver 6.5 and mapped the same name in cloudstack's guest network 
option but I cannot ping the default gateway from the secondary storage 
VM and therefore I cannot download the initial CentOS 5.6 template and 
start creating the VM's

Thanks in advance

Luke
