Hi Evgeniy, Physical networks consist of a mapping between a certain ACS type of networks (guest, management, storage, public) and the physical NICS. You can very well have just one physical network for all types of networks, and many do that, but ideally you would segregate, let me give you a few examples.
Hosts with 2 NICs: one physical network for everything. Hosts with 4 NICs: two physical networks, one for front end (Public, Guest, Management) and another for back end (storage). Host with 6 NICs: three physical networks, one for Public and Guest, one for Management and another for back end (storage). Host with 8 NICs: as above, but you can then segregate different types of Guest networks in different NICs Your case is clearly the second one, so you have to create two physical networks and set them with traffic labels which match the name of the network on Xen (that's how ACS knows on which NICs to deploy which network) Hope that helps you to understand it.

Can someone explain me concept of Physical Networks? Now I have Xen hosts with 4 NICs. They are grouped in 2 bonds. On 1 bond I have Management, Guest and Public VLANs. On other - Storage VLANs. When I deploy ZONE should I create 2 Physical Networks? Or I can create 3 (1?) network for example? I want to deploy Advanced Zone (without SG) I read article from ShapeBlue (https://www.shapeblue.com/understanding-cloudstacks-physical-networking-architecture/) but it doesn't help me:) Best regards, Evgeniy.
