When you use Virtual Machine Manager (VMM) to manage a host on a perimeter network, you can deploy virtual machines on the host from within the internal network. However, after you deploy virtual machines on a host on a perimeter network, you cannot migrate those virtual machines back to a host on the internal network or to another host on the perimeter network.

Before you can add a host on a perimeter network, you must install a VMM agent locally on the host. For more information, see How to Add a Host on a Perimeter Network.

When you install an agent locally on a host on a perimeter network, the Agent Setup Wizard automatically generates a local account with administrator privileges on the host and a set of credentials for the account. It then encrypts the account credentials and other agent access information into a security file. After you add the host, VMM uses the credentials to communicate with the agent on the host.

You cannot change the credentials for the local account during setup; however, you can update the password after you have added the host. For more information about updating the password, see How to Update the Agent Password on a Host on a Perimeter Network.
