How to Isolate a Virtual Machine#

Isolating a virtual machine (VM) can be done in several ways, depending on the specific requirements of the environment. Below are two common methods for isolating a VM within VergeOS.

Remove the Attached Network from the VM#

This method essentially simulates unplugging a network cable from the VM, making it function without any external connectivity. It’s suitable when the VM doesn’t need to communicate with any other network.

Steps to Remove the Network:#

  1. Navigate to the Virtual Machine Dashboard.
  2. Click on NICs in the left navigation menu to access the VM's virtual network adapters.
  3. Select the NIC you want to edit and click Edit from the left navigation menu.
  4. In the NIC configuration window, use the drop-down list to change the Network from its current value to --None--.
  5. If the VM has multiple NICs, repeat this process for all active/enabled NICs.

By removing the network from all NICs, the VM will no longer have network access.

Create a New Internal Network#

If the VM requires connectivity but still needs to be isolated from other networks, creating a new internal network with no other VMs connected is the preferred solution.

Steps to Create an Internal Network:#

  1. From the VergeOS dashboard, navigate to Networking and create a new Internal Network.
  2. Set a Default Gateway for outbound access if needed.
  3. After the internal network is created, return to the VM dashboard and update the NIC to attach the VM to the newly created internal network.

For more detailed instructions on creating internal networks, refer to the VergeOS inline help under Networking in the Internal Networks section.

This method allows the VM to have restricted network access while still providing outbound connectivity through the internal network.
