Setting Up Two Separate Host-Only Networks

For some configurations, you may need to set up more than one host-only network on the same host computer.

You may, for example, want to have two virtual machines connected to one host-only network, and at the same time have other virtual machines connected to another host-only network so the network traffic on each network is isolated.

Or you may want to test routing between two virtual networks. Or test a virtual machine with multiple network interface cards - without using any physical Ethernet adapters.

On Windows hosts, the first host-only network is set up automatically when you install VMware Workstation.

On Linux hosts, the first host-only network was set up when you ran the vmware-config.pl script after you installed VMware Workstation, provided you agreed to install host-only networking. If you did not agree to use host-only networking, you need to run the script again to set up host-only networking.

To set up the second host-only network, follow the steps outlined below for your host operating system.

Setting Up the Second Host-Only Interface - Windows NT Host

Follow these steps to set up the second host-only interface on Windows NT.

Open a command prompt window. Change to the VMware Workstation programs folder. If you accepted the default path, use this command:
cd C:\Program Files\VMware\Programs
Run the following command:
vnetconfig -ih vmnet2

Setting Up the Second Host-Only Interface - Windows 2000 Host

Open the Control Panel (Start > Settings > Control Panel).
Start the Add/Remove Hardware Wizard from the Control Panel.
Note: You must have sufficient privileges to do this.
Click Next to continue past the Welcome screen.
Select Add/Troubleshoot a Device and click Next.
Wait while Windows searches for new Plug and Play devices, then select Add a New Device from the Choose a Hardware Device screen and click Next.
Select No, I want to select the hardware from a list and click Next.
Select Network Adapters from the list and click Next.
Select VMware, Inc. from the manufacturers list on the Select Network Adapter screen to get the list of available host-only network adapters. Select VMware Virtual Ethernet Adapter (for VMnet2) and click Next.
Click Next in the Start Hardware Installation screen.
Click Yes when prompted that the Microsoft digital signature is not present for the software about to be installed.
Click Finish on the screen that indicates the adapter has been installed.

Setting Up the Second Host-Only Interface - Windows XP or Windows .NET Server Host

Start the Add Hardware Wizard.
Start > Control Panel > Add Hardware
Note: You must have sufficient privileges to do this.
Click Next.
When prompted, select Yes, I have already connected the hardware.
On the screen that lets you select the hardware, select Add a new hardware device, then click Next.
Select Install the hardware that I manually select from a list (Advanced).
Select Network Adapter.
Select VMware, Inc. as the manufacturer.
Select the host-only adapter for the appropriate VMnet.
Click Yes when prompted that the Microsoft digital signature is not present for the software about to be installed.
Click Finish on the screen that indicates the adapter has been installed.

Setting Up the Second Host-Only Interface - Linux Host

As root (su), run the VMware Workstation configuration script.
/usr/bin/vmware-config.pl
Use the wizard to modify your configuration. After asking about a NAT network, the script asks:
Do you want to be able to use host-only networking in your virtual machines?
Answer Yes.
The wizard reports on host-only networks that you have already set up on the host or, if none is present, configures the first host-only network.
The wizard asks:
Do you wish to configure another host-only network?
Answer Yes.
Repeat this step until you have as many host-only networks as you want. Then answer No.
Complete the wizard. When it is finished, it restarts all services used by VMware Workstation.
Run ifconfig. You should see at least four network interfaces - eth0, lo, vmnet1 and vmnet2. If the VMnet interfaces do not show up immediately, wait for a minute, then run the command again. These four interfaces should have different IP address on separate subnets.

Configuring the Virtual Machines

Now you have two host-only interfaces (VMnet1 and VMnet2). You are ready to configure your virtual machines for one of the following scenarios:

The virtual machine is configured with one virtual Ethernet adapter, and that virtual adapter is connected to the default host-only interface (VMnet 1).
The virtual machine is configured with one virtual Ethernet adapter, and that virtual adapter is connected to the newly created host-only interface (VMnet2).
The virtual machine is configured with two virtual Ethernet adapters. One virtual adapter is connected to the default host-only interface (VMnet1) and the other virtual adapter is connected to the newly created host-only interface (VMnet2).

Scenario 1 - Connect to the Default Host-Only Interface

Create the virtual machine using the New Virtual Machine Wizard (on a Windows host) or Configuration Wizard (on a Linux host) or use an existing virtual machine.
Launch VMware Workstation and open the virtual machine.
Edit the configuration using the Configuration Editor (Settings > Configuration Editor).
Windows host: Select Network Adapter, then select Host-only (VMnet1) from the drop-down list on the right.
If no network adapter is shown in the list of devices, click Add, then use the Add Hardware Wizard to add an adapter.
Linux host: Click the + sign to expand the Ethernet Adapters list and select the first adapter. From the Connection Type drop-down list on the right, select Host-only.
If the list of devices indicates the adapter is not installed, click Install.

Scenario 2 - Connect to the Newly Created Host-Only Interface

Create the virtual machine using the New Virtual Machine Wizard (Windows hosts) or Configuration Wizard (Linux hosts) or use an existing virtual machine.
Launch VMware Workstation and open the virtual machine.
Edit the configuration using the Configuration Editor (Settings > Configuration Editor).
Windows host: Select Network Adapter, then select Custom (VMnet2) from the drop-down list on the right.
If no network adapter is shown in the list of devices, click Add, then use the Add Hardware Wizard to add an adapter.
Linux host: Click the + sign to expand the Ethernet Adapters list and select the first adapter. From the Connection Type drop-down list on the right, select Custom. In the VMnet field, type /dev/vmnet2.
If the list of devices indicates the adapter is not installed, click Install.

Scenario 3 - Connect to Two Host-Only Interfaces

Create the virtual machine using the New Virtual Machine Wizard (on a Windows host) or Configuration Wizard (on a Linux host) or use an existing virtual machine.
Launch VMware Workstation and open the virtual machine.
Edit the configuration using the Configuration Editor (Settings > Configuration Editor).
Windows host: Select the first network adapter in the list of devices, then select Host-only (VMnet1) from the drop-down list on the right. Select the second network adapter in the list of devices, then select Custom (VMnet2) from the drop-down list on the right.
If you need to add one or more network adapters, click Add, then use the Add Hardware Wizard to add an adapter.
Linux host: Click the + sign to expand the Ethernet Adapters list and select the first adapter. From the Connection Type drop-down list on the right, select Host-only.
If the list of devices indicates the adapter is not installed, click Install.
Select the second adapter and, from the Connection Type drop-down list on the right, select Custom. In the VMnet field, type /dev/vmnet2.
If the list of devices indicates the adapter is not installed, click Install.

At this point you can power on the virtual machine and install your guest operating system. In scenarios 1 and 2 you see one AMD PCNet Family Adapter. In scenario 3 you see two AMD PCNet Family Adapters within the guest. Configure the Ethernet adapters as you would physical adapters on a physical computer, giving each an IP address on the appropriate VMnet subnet.

On Windows hosts, you can open a command prompt and run ipconfig /all to see what IP addresses each host-only network is using.

On Linux hosts, you can open a terminal and run ifconfig to see what IP addresses each host-only network is using.
