## Declaration

```

## Parameters

- `network`: The logical network object

## Return Value

## Discussion

Discussion To ensure proper isolation between application processes, a virtual machine (VM) can only use the network that the same application process creates. If an application’s VM tries to use a network that another application’s VM creates, initialization fails. For more information on vmnet configuration requirements and restrictions, see vmnet The following example demonstrates how to create and initialize a custom network using VZVmnetNetworkDeviceAttachment.
