Explanation:
The type of VM network you set up depends on the isolation settings for the logical network:
Network virtualization: If the logical network is isolated using network virtualization you can create

multiple VM networks for a logical network. Within a VM network tenants can use any IP addresses they want for their VMs regardless of the IP addresses used on other VM networks. Tenants can also configure some network settings.
VLAN: If the logical network is isolated using VLAN or PVLAN you'll create on VM network for each

network site and VLAN in the logical network.
No isolation: If the logical network is configured without isolation you'll create a single VM network

linked to a logical network.
