> I prefer to use VirtualBox because I am unable to make QEMU/KVM work, since I am not a rocket scientist.

What this translates to is "I did not want to read the large and comprehensive QEMU/KVM documentation, go through each option one by one, take notes, and specify the ones I wanted."

Which is ... totally fine. `qemu` has a lot of options. But that's why they make frontends. You want a scary, difficult command to work with? Try `tc`. I would NEVER touch raw `tc` commands when configuring QoS - FireQoS all the way.

When I experimented with `qemu` to make a Debian-based headless hypervisor, I did have to put some time in it. I had to make some scripts to convert some easier-to-make "config" files into `qemu` commands (in addition to making the `tap` network interfaces for virtual networking). Got it working and it did its thing. It was cool that it could be done - launch VMs from a script with no need for a GUI.
