“Oracle VM VirtualBox (formerly Sun VirtualBox, Sun xVM VirtualBox and Innotek VirtualBox) is a free and open-source hypervisor for x86 computers currently being developed by Oracle Corporation. Developed initially by Innotek GmbH, it was acquired by Sun Microsystems in 2008 which was in turn acquired by Oracle in 2010.”
In this tutorial you will see how to install VirtualBox on Windows Server 2016. The process for the install will be the same for windows 1o.
After recently updating Windows 10, none of my VMs in VirtualBox would power on. I kept receiving an error that read:
(Interface (‘VirtualBox Host-Only Ethernet Adapter’) is not a Host-Only Adapter interface (VERR_INTERNAL_ERROR) SOLVED

Step 2
In the screen that appears I then clicked Create, to create a new Host Only Network.
Step 3
I then right clicked on the VM i wanted to start and clicked settings.
This is a tip which has got be out of a few binds before. So what happens is you are called to a job to troubleshoot a issue on a Linux server. You access the terminal and the keys you are typing are not appearing on the screen. For example, when you type @ you see ” and when you type # you see \.
This is happening because the terminal is expecting input from a US keyboard and you are using a UK keyboard.
You can solve this very quickly by typing the command:
sudo loadkeys uk
When this command is run successfully you should see a screen that looks like the one below.
Your keys should now be working correctly.
A video that shows this process can be found here:
