Virtual Switch Networking Options in Virtual PC for Windows (824509)

MORE INFORMATION

Use Virtual Switch networking to help you perform advanced networking functions on a Virtual PC guest PC. Networking features and functions that require Virtual Switch networking include the following:

• Server software that uses predefined port numbers
• Remote logon
• Network performance analysis
• Remote shells

When you configure your guest PC Networking settings to use the Virtual Switch option, you have the following routing options:

• Local only. The guest PC does not send or receive information to or from the host PC. The guest PC does not send or receive information over your network. This setting can be useful for testing network protocols.
• Local and host. The guest PC sends and receives information over your network. In this case, the guest PC appears and behaves like any physical computer on your network.
• Local, host and external. This is the default setting. The guest PC can send and receive information on the network by using the network adapter that is configured in the Virtual Switch settings in Virtual PC Preferences. The guest PC can also do this with other guest PCs and with the host PC. In this case, the guest PC appears and behaves like any physical computer on your network, and therefore it can communicate with the host PC.
• External Only. Other guest PCs and the host PC do not receive information directly from the guest PC. Network information is sent and received on the network through the network adapter that is configured in the Virtual Switch settings in Virtual PC Preferences. This setting is useful for testing without affecting your host or your other guests.

1. In the Virtual PC window, click the guest PC that you want to configure, and then click Settings.
2. Under PC Settings, click Networking.
