Install SSH Server on your VM

Install ssh server on your VM. Open a terminal and type:

sudo apt install openssh-server -y

If you are unable to open the VM GUI (some MacOS hosts crashes the VM when it tried to display its GUI Desktop), download the VM with openssh alreadly installed from this link.

Setup Port Forwarding

In order to ssh into your Guest VM from your host, you need to setup some port forwarding rules. The default ports for SSH and jupyter are 22 and 8888, respectively.

  1. In Virtualbox, right-click on “ECE4960” and select “Settings”.
  2. Select the “Network” tab and under the “Adapter 1” pane, expand the “Advanced” tab.
  3. Click on “Port Forwarding” and a new row entry with the following information:
   
Name SSH
Protocol TCP
Host IP 127.0.0.1
Port 2200
Guest IP 10.0.2.15
Guest Port 22
  1. Create another row entry:
   
Name jupyter
Protocol TCP
Host IP 127.0.0.1
Port 8888
Guest IP 10.0.2.15
Guest Port 8888
  1. Click the button “OK” in the window.
  2. Click the button “OK” in Settings window.

SSH into your Ubuntu Guest VM:

  1. To SSH into your Ubuntu Guest VM (with X11 Forwarding): 
    ssh -p 2200 artemis@127.0.0.1

Managing VM from the terminal

You can start a VM headless,(Use the small arrow next to the start button), power off and shutdown from Virtualbox. Virtualbox also provides a commandline interface.

  • Start a VM: 
      VBoxManage startvm "ECE4960" --type headless
  • Find the status of all the VMs: 
      VBoxManage list vms --long | grep -e "Name:" -e "State:"
  • Return 1 is the VM “ECE4960” is running: 
      VBoxManage list runningvms | sed -r 's/^"(.*)".*$/\1/' | grep 'ECE4960' | wc -l
  • Poewr off the VM: 
      VBoxManage controlvm ECE4960 poweroff
  • Save the state of the VM: 
      VBoxManage controlvm ECE4960 savestate
  • Shutdown the VM: 
      VBoxManage controlvm ECE4960 acpipowerbutton

File Access

Setup a shared folder as instructed in the Lab 1(b): VM Setup. Once you ssh into your VM, you can access the files at:

/media/
