Multipass

wikipedia:multipass (December 2019 v1.0) allows to orchestrate Ubuntu virtual machine instances on Linux, Windows and macOS. It uses KVM on Linux, Hyper-V on Windows and HyperKit on macOS, supported since July 2018, to run the VM with minimal overhead. Since August 2020 (v1.4) it also included bridged networking support.
