microvms as espoused by things like firecracker offer full machines but have tradeoffs like no gpu (which makes it boot faster)
hyperlight shaves way more off - (eg: no access to various devices that you'd find via qemu or firecracker) it does make use of virtualization but it doesn't try to have a full blown machine so it's better for things like embedding simple functions - I actually think it's an interesting concept but it is very different than what firecracker is doing

Microsoft's blog post on Hyperlight got my attention a while ago: https://opensource.microsoft.com/blog/2025/02/11/hyperlight-...
I am way out of my depth here, but can anyone make a comparison with the "micro virtual machines" concept?
