unikernels VS lima

About unikernels https://github.com/cetic/unikernels?tab=readme-ov-file#unike...

Another possibility to switch from Docker containers are the so-called Unikernels. These are briefly mentioned here for the sake of completeness, even though they currently have no significance in the Kubernetes context. An interesting blog post on the topic can be found on Hackernoon. It is an interesting construct that may one day find its way into the world of Kubernetes if containers can be replaced by unikernels. Currently, the use of unikernels would not be feasible in my opinion.

You can run a virtual machine (e.g. lima) from inside a nix-shell, exactly as you would do with a regular shell.

for others similarly curious, here's an example of the thing: https://github.com/noop-inc/template-java-spring-boot/blob/m...

they seem to be using the excellent lima <https://github.com/lima-vm/lima#readme> for booting on macOS; I run colima for its containerd and k8s support but strongly recommend both projects $(brew install lima colima)

Lima is what I use as well. It's quick and easy to just fire up a VM with default settings, but also very easy to configure with different file sharing options, port forwarding, different linux distributions, etc. (their examples are also pretty good IMO [1]).

In particular I use it to run an amd64 VM, which I need to run a stubborn service for work that doesn't run on arm CPUs.

Lima (1) is a project that packages Linux distros for MacOS and executes them via qemu in the backend. Maybe you could solve your problem by launching one of their vms and inspecting the command line it generates. You might find an option you were missing.

I'd say Lima and Colima should be enough for most use cases:

Lima wraps QEMU in a simple CLI, with neat features for container users, such as filesystem sharing and automatic localhost port forwarding, as well as DNS and proxy propagation for enterprise networks. Rancher Desktop wraps Lima with k3s integration and GUI.
