Common Scenarios for Networking in Virtual Machine Manager

On a host, use only part of the bandwidth of a physical network adapter, or a teamed set of network adapters, for managing that host.

• Configure a native port profile for virtual network adapters that will limit the amount of bandwidth. Also configure a logical switch that includes that port profile.
  
  
• Assign the logical switch to the management adapter, either in the host’s properties, or in a host profile that you use for deploying Hyper-V hosts.

On a host, configure teaming of multiple physical network adapters for increased availability.

• Configure a logical switch and associate it with multiple physical adapters on the host.
  
  
• The logical switch that you create for this purpose must use Team for the uplink mode.

How to Create a Host Profile in VMM

Connect virtual machines to a network that serves a particular function in your environment, for example, the “Backend,” “Frontend,” or “Backup” network. In other words, associate IP subnets and, if needed, virtual local area networks (VLANs) together into named units ("logical networks") that virtual machines can use.

• Logical networks, which were introduced in System Center 2012, can still be used in System Center 2012 SP1 by creating a logical network, then creating a VM network that specifies that logical network and specifies No isolation. The VM network will function as a logical network with no isolated networks within it. (For more options with VM networks, see the last seven rows in this table.)
  
  
• Only one VM network that is configured with No isolation can be assigned to each logical network.

In a virtualized network environment, monitor network traffic, use quality of service (QoS) to control network bandwidth usage, or enhance the level of security.

• In VMM, create a logical switch and associate a virtual switch extension with it. For example, use a switch extension that supports QoS (through the switch extension provider).
  
  
• Before you can associate a switch extension with a logical switch, you must install provider software on the VMM management server. Some providers are included in VMM. You can also obtain them from switch manufacturers and add them to VMM.

Configure settings on your forwarding extension and then apply them consistently in your virtualized environment. Settings can include network objects, such as logical networks, network sites, and VM networks.

• In VMM, add the switch extension manager for your forwarding extension. To do this, you must first install provider software that you obtain from the switch manufacturer.
  
  
• Then create logical switches, which bring together multiple network settings and capabilities that you want to make available on particular hosts.

Move virtual machines and their associated networks in a single operation.

• When you configure a virtual machine or virtual machine template and you specify a VM network that uses network virtualization, the VM network moves when the virtual machine is moved. (A VM network uses network virtualization if the logical network on which it is configured allows network virtualization.)

How to Create a Virtual Machine Template

Connect virtual machines on VM networks to computers on connected physical networks. (For a similar scenario for a hoster, see the last line in this table.)

• Create a VM network that uses network virtualization, and configure it with a gateway to Local networks. A VM network uses network virtualization if the logical network on which it is configured allows network virtualization.
  
  
• Before you configure the VM network to use the gateway, you must obtain provider software for the gateway and install it on the VMM management server.
  
  
• The gateway will act as a router to the physical network.

Manage networks that use familiar VLAN technology for network isolation, but use VMM to simplify the management process.

• Obtain information about the isolated VLANs that have been created within the physical network. Then, in VMM, create a logical network and specify Network sites within this logical network are not connected. Follow additional steps in Configuring VM Networks and Gateways in System Center 2012 SP1.
  
  
• The completed configuration has one VM network for each isolated VLAN in your physical network.

In the hosted environment that you provide, allow each tenant, client, or customer to have their own networks that are isolated from the networks of other tenants, clients, or customers.

• Use network virtualization. To do this, create a logical network (the foundation), specify that the logical network allows for VM networks that use network virtualization, and then create multiple VM networks on top of the logical network. Provide one or more VM networks for each tenant, client, or customer.

In the hosted environment that you provide, allow your tenants, clients, or customers to “Bring your own IP”—in other words, you offer them an environment in which they can use whatever IP addresses they want for their virtual machines.

• Use network virtualization. To do this, create a logical network (the foundation), specify that the logical network allows for VM networks that use network virtualization, and then create multiple VM networks on top of the logical network. Provide one or more VM networks for each tenant, client, or customer.

In the hosted environment that you provide, allow your tenants, clients, or customers to configure some aspects of their own networks, based on limits that you specify.

• Use network virtualization, and give each tenant access to the appropriate networks through the Tenant Administrator role in VMM. (See the previous row in this table for information about network virtualization.)

In the hosted environment that you provide, allow your tenants to connect their virtual machines to systems on their own premises. (From the tenant perspective, the connection is between “the cloud” and their local network.)

• Create the tenant’s VM network so that it uses network virtualization, and configure it with a gateway to Remote networks. A VM network uses network virtualization if the logical network on which it is configured allows network virtualization.
  
  
• Before you configure the gateway, you must first obtain the provider software that works with the tenant’s gateway and install that provider on the VMM management server.
  
  
• This configuration provides a site-to-site, virtual-private-network (VPN) connection from the tenant’s VM network (in the hosted environment that you provide) to a VPN gateway on the tenant’s premises.
