Running qemu on a linux platform means you have the ability to use hardware acceleration via KVM. This allows you to access the virtualization features of your processor. For MacOSX we aren’t as lucky since there currently is no port of KVM for MacOSX.

As of MacOSX 10.10 apple introduced hypervisor.framework which is their way of acccessing the virtualisation features of the processor. The downside to hypervisor.framework is it isn’t as readily supported in other applications such as Qemu. It also doesn’t have the ability to do nested virtualization which is important if you want to run something like EVE-NG.

Docker is a platform which allows you to create an application which can be run in a loosely isolated enviroment. When combined with EVE-NG, we can quickly create applications inside our lab envrioment. An example of this is, instead of insalling a linux server with apache, you can just deploy a prebuilt docker container with apache already installed and configured. This container can then be connected to a virtual router in your lab.

Resizing paritions is not something I find myself doing very frequently so I tend to forget the procedure. Below is what I did to resize a parition in Ubuntu16.04. This server is a vm running inside esxi.
