Canonical Releases Multipass 1.0 As "A Mini-Cloud On Your Workstation"
They self-describe Multipass 1.0 as "a mini-cloud on your workstation using native hypervisors of all the supported plaforms (Windows, macOS and Linux), it will give you an Ubuntu command line in just a click ("Open shell") or a simple multipass shell command, or even a keyboard shortcut."
Multipass is akin to Vagrant and similar VM managers. Multipass makes use of KVM on Linux, Hyper-V on Microsoft Windows, and HyperKit on macOS. VirtualBox support is also there for Windows and macOS. Multipass is basically the Canonical/Ubuntu focused approach for being able to quickly and easily fire up Ubuntu VMs and integrates with their ecosystem around Snaps and the like.
