Multipass is a lightweight VM manager for Linux, Windows and macOS. It's designed for developers who want a fresh Ubuntu environment with a single command. It uses KVM on Linux, Hyper-V on Windows and HyperKit on macOS to run the VM with minimal overhead. It can also use VirtualBox on Windows and macOS. Multipass will fetch images for you and keep them up to date.
Since it supports metadata for cloud-init, you can simulate a small cloud deployment on your laptop or workstation.

And when you want to completely get rid of it:
$ multipass purge
multipass help
multipass help <command>
Here's a set of steps to build and run your own build of Multipass:
cd <multipass>
apt install devscripts equivs
mk-build-deps -s sudo -i
cd <multipass>
git submodule update --init --recursive
mkdir build
cd build
cmake ../
make
First, install multipass's runtime dependencies. On amd64 architecture, you can achieve that with:
sudo apt update
sudo apt install libgl1 libpng16-16 libqt5core5a libqt5gui5 \
libqt5network5 libqt5widgets5 libxml2 libvirt0 dnsmasq-base \
dnsmasq-utils qemu-system-x86 qemu-utils libslang2 iproute2 \
iptables iputils-ping libatm1 libxtables12 xterm
Then run multipass's daemon:
sudo <multipass>/build/bin/multipassd &
Copy the desktop file multipass clients expect to find in your home:
mkdir -p ~/.local/share/multipass/
cp <multipass>/data/multipass.gui.autostart.desktop ~/.local/share/multipass/
Optionally, enable auto-complete in bash:
source <multipass>/completions/bash/multipass
Finally, use multipass's clients:
<multipass>/build/bin/multipass launch --name foo # CLI client
<multipass>/build/bin/multipass.gui # GUI client
