I was talking about network interface of the vm configuration, not /etc/network/interfaces of the host ;)

I believe that add it to network interface config isn't good idea, because 
if we have several VMs in the same host and the network interface config was 
changed, will be unpleasant to need to do a shutdown the VMs and restart the 
physical server for that the changes take effect
