Should one create NAT on KVM host?

[Dan Dong]

Hi, All,
  I have a question on basic network configuration of cloudstack:
1. The Management Server-->192.168.0.100
2. One KVM host--> 192.168.0.101
3. System VMs--> 192.168.0.110-192.168.0.120
3. The guest VMs-->192.168.0.150-192.168.0.250

That is, they are all in the same network of 192.168.0.0/24, should I make
NAT on the KVM host to let SSVM running on it to contact the Management
Server( and the outside world)?

(SSVM<->KVM Host<->Management Server)

Cheers,
Dan
