Proxmox 4.1. Guest systems do not see networks?

Question

Computer networks

Hello.
There is a server with Proxmox 4.1. in a data center with "white" IP. Installed by default. The host is normally accessible, there are no firewalls.
But the guest systems do not see the network. I don’t know which way to dig, please indicate the direction where to move.
Thank you.
