Where did QEMU come from in my Startup Disk Creator?

Yesterday I was playing with Startup Disk Creator in Ubuntu 16.04.

After doing a Live install to USB, I noticed a "Test Disk" button.

test disk button

I never noticed this button before so I pressed it.

A QEMU window opened, loading the OS from the newly made Live thumb drive.

QEMU

There was no need to reboot.

Great feature I thought, just like MultiBootUSB has.

I tried to duplicate the install, booting from the new thumb drive.

No luck, the Test Disk button was gone.

My question

How did/do I add this "Test Disk" feature to Startup Disk Creator on a new install.

Bonus Question

How would I add this feature to mkusb?

I recall having installed MultiBootUSB and QEMU previously on the computer, but I have not been able to duplicate the merging of QEMU and SDC since.

  • I tried installing MultiBootUSB 9.2.0 and found that QEMU no longer comes with the tool, you need to download it yourself.

    I tried installing several versions of QEMU, qemu-system, qemu-kvm,

    What finally worked was:

    sudo apt-get install qemu-kvm qemu virt-manager virt-viewer libvirt-bin
    

    My Startup Disk Creator now shows the "Test Disk" button.

    For now I guess I will just have to run QEMU manually when working with mkusb, unless @sudodus comes up with something.
