![]() There are ways to route traffic around if you need to do that. So what do you do with it? By default, the machine starts up with a private network that you can only access from the host machine. You can control them with start and stop. Once you have a bunch of virtual machines, you might want to see how they are doing: multipass list You can also provide a name for the virtual machine: multipass launch -c 4 -m 6G -d 10G -n hackaday-vm bionic On the Run Say you want 4 CPUs, 6G of RAM, and a 10G disk. However, you usually want a little more control since the default is one CPU core, a gigabyte of RAM, and 5G of disk storage. You can launch a default instance by issuing the command: multipass launch bionic Suppose you want to do some testing in a Ubuntu bionic (18.04) instance. Naturally, most of the images are Ubuntu versions, although there are a few other appliances like anbox and nextcloud available. ![]() You can see all the images available by running: multipass find The /proc/cpuinfo file should have a vmx or svm flag (actually, several of them one for each core). You should be sure that you are on a computer that can support virtual machines. The process varies by platform, but on Ubuntu, installing Multipass is as easy as: sudo snap install multipass If you have a set configuration, you can even set up predefined setups using a YAML file. Once you have it installed, starting up a new Ubuntu instance is trivial. Granted, most of the virtual machines in question are variations of Ubuntu, but there are some additional images available, and you can create your own. Using Multipass from Canonical, the makers of Ubuntu, you can easily spin up virtual machines under Linux, Mac, or Windows. Wouldn’t it be nice if you could do the same for virtual machines? You can. It wasn’t long ago that we looked at easily creating Docker containers from the command line so you could just easily spin up a virtual environment for development.
