Virtual Network Implementation 19
Advantages
• The internal virtual network enables isolation of VMs from the
external network.
NOTE: The internal virtual network is not recommended for environments
utilizing failover clustering because the internal network is localized to each host.
Figure 4-2 shows the logical representation of the internal virtual network
configuration. It additionally shows two VMs and the parent partition
connected to the virtual switch.

External Virtual Network
In Hyper-V, you can use the external virtual network to allow network
communication between VMs, the parent partition, and the external
network.
When you select and configure the external virtual network:
1
A virtual switch is created and connected to the VMs. See the vSwitch #1
in Figure 4-3.
2 A new virtual network adapter is created and connected to the
parent partition.
