You can select the virtual network interface cards (NICs) to create on the virtual machine so that the virtual machine can communicate with other hosts and virtual machines. For each NIC, select the network and adapter type.

Caution: Because virtual machines share their physical network hardware with the host, the accidental or malicious bridging of two networks by a virtual machine can occur. Spanning Tree protocol cannot protect against these occurrences.

You can select only four NICs during virtual machine creation. You can add more virtual NICs by selecting Edit the virtual machine settings before completion on the Ready to Complete page of the wizard, or by editing the virtual machine after it is created.

For more information about networking, see the vSphere Networking documentation.


  1. On the Network page of the New Virtual Machine wizard, select the number of NICs to connect from the drop-down menu.
  2. For each NIC, select a network and adapter type from the drop-down menus
    Depending on the host version and the guest operating system, a choice of adapter types for each virtual NIC might not be available. In many cases, only one type of adapter is supported. If more than one type of adapter is supported, the recommended type for the guest operating system is selected by default.
  3. (Optional) Click Connect at Power On to connect the NIC when the virtual machine is powered on.
  4. Click Next to add a SCSI Controller.
