Virtualbox not responding after installing ASLA modules for jibri

I followed the following steps -

  1. Created a clean 16.04 virtualbox install.
  2. sudo su
  3. apt install linux-image-extra-virtual
  4. echo “snd-aloop” >> /etc/modules
  5. modprobe snd-aloop
  6. lsmod | grep snd_aloop

These steps were mentioned in the jibri readme document.

After doing this, whenever I next load up the virtualbox instance, it boots up successfully but I’m unable to see/click the mouse pointer on the virtualbox screen, or use any keyboard shortcuts or do pretty much anything at all.

My knowledge of linux, kernels, virtualbox etc. is very limited, so can someone diagnose what’s the issue here?
