How to Solve Host-only Adapter Error in VirtualBox (100% Work)

VirtualBox is software that is used to virtualize the operating system into the main operating system. By using this software, it allows us to install one or more other operating systems into our computers or laptops.

Unlike the way dual boot works, the virtualization performed by VirtualBox does not directly affect your hardware. So VirtualBox will create virtualization on your hardware starting from the virtual CPU, memory, hard disk and so on.

Even so, the operating system installed on VirtualBox is exactly the same as the original, starting from the desktop appearance, features and so on.

How to Solve Host-only Adapter Error in VirtualBox

When using VirtualBox, you may have experienced an error when running your virtual machine (the name for the operating system installed in VirtualBox). For example, an error that reads more or less “Failed to open/create the internal network……“. How to solve the host-only adapter error in VirtualBox can be done in the following way:

1. When you open a virtual machine in VirtualBox and get an error similar to the image below, it means that the Host-only Adapter used in the virtual machine has a problem or is used by another virtual machine.

2. For how to fix it, click File > Host Network Manager.

3. After that select Create to create a new Host-only Adapter.

4. If you get a warning like this, just select it Yes.

5. The new Host-only Adapter we just created (Host-only Adapter #3) and ready to use.

6. Next select which virtual machine you want to run then click Settings.

7. Then on the menu Network, select Host-only Adapter (ie Host-only Adapter #3) which we just created.

8. Done, run the virtual machine as usual.

That’s a tutorial on how to easily solve the host-only adapter error in VirtualBox. In the future, make sure you don’t use the same host-only adapter on different virtual machines. So simply, 1 host-only adapter for 1 virtual machine. Hopefully this tutorial is useful and easy to understand!
