Your SSH server will start up automatically. On the virtual machine, install SSH using the command: sudo apt install openssh- server Launch VirtualBox and then start your Ubuntu virtual machine from the GUI. In case you don't have a guest OS, here's how to install Ubuntu as a guest operating system on VirtualBox. This guide will demonstrate the process with Ubuntu Desktop as the host OS and Ubuntu Server as the guest OS in VirtualBox, but the procedure is basically the same regardless of the operating system you are using. Also, the PC you are initiating the SSH connection from needs to have an SSH client. To be able to SSH into another PC, the system must be running an SSH server and its service should be enabled. Of course, you can use SSH on full-blown desktop environments too.

SSH is one of the primary ways of administering and interacting with Linux servers that do not come with a GUI. These instructions work with VirtualBox 6.0, I have not tested it with older versions.Step 1: Installing SSH on the Virtual Machine When you get the prompt that says Press enter to continue.

Adjust memory as necessary, but I left it at the default of 1GBĬ. Extra Notes: Keep in mind that if you decide to create a large VM, you must have enough space on the hard disk. Go to the system tab, and disable I/O APIC (clear the check)ī. In the new window that appears, enter a name, select a location on which to store the VM, specify the VM type as Linux, and the Version as Ubuntu (64-bit).

Before you start the VM, go to settings:Ī.

I then created a new Virtual Machine, said it was Linux and Ubuntu 64-bit, and pointed the storage to the vdi image I created in the previous step.

I then use VBoxManage to convert the raw disk image to VDI: VBoxManage convertdd ubuntu-core-18-amd64.img core18.vdi.

After some initial issues, I figured out how to configure the VirtualBox VM so that it would successfully run Ubuntu Core 18.īelow are the steps I took to make it work: I had a conversation yesterday with a user who was having issues running Ubuntu Core 18 inside of a VirtualBox VM running on Ubuntu 18.04.
