We Rebuilt the Linux MicroVM Stack on Apple Silicon

Oh yes. I discovered that there are two scrollbars. By clicking somewhere in the blog text, you activate the inner one and then scrolling with the keyboard works.

Sorry about that - just pushed a fix :)

I thought it was just me. Super weird.

Wow, that's actually an impressive new failure mode; and it happens on Safari too.

Virtualization.framework isn't particularly limited, for what it is... given they're using Firecracker on Linux, it makes sense to use a similarly high level API on macOS.

(One could add a Hypervisor.framework backend to Firecracker, though I'd be surprised if AWS accepted it.)

Hacker News is so utterly detached from reality at times, and comments like these really drive that home.

No, they're realists.

Plus show me an off the shelf solution to MDM that exists in the Linux space? (Not too mention an easy to buy consumer devices which supports suspend/resume correctly in 2026, not even Windows can do that any more)

Apple is crap and evil about many things, but at least here they know their paying audience...

This is unbelievably cool. How did you use AI for this? Absolutely not suggesting there's anything wrong with it - quite the contrary. I find AI is most useful for these lower level driver type projects such as yours that one knows are possible but that would be very onerous for a human to implement. For example the guy who re-wrote a driver from scratch for his HP Printer the other day.

Do you think you could have done this without AI? I've been migrating people off of AWS recently and it was absolutely made possible (or at least expedient) by AI.

Because prices? Have you seen how much Apple products cost these days?

Also, M1/M2 are perfectly fine and capable hardware. It's hard to justify the upgrade outside some artificial constraints Apple would bring in with a macOS update.

You’d be surprised. I got an absolute boat anchor of a 2019 MacBook when I started a job in early 2022. I requested a new one in late 2023 because company policy is to refresh laptops every 4 years - whoever was on the other end of my support ticket interpreted the policy as four years from issuance and denied me.

it's pretty common to be running a 4 year old computer in most companies I've worked.

I think they plan for 3 years but in reality it becomes closer to 4 (because they don't plan the refresh during the actual hardware refresh cycle, so you'll end up with a computer that was released in September the year before in like August the year after).

I've never worked anywhere that replaced my computer after 2 years.

I am on an M1 macbook pro. My company will upgrade me anytime I want.

I haven’t asked because my current laptop is more than ok.

Things were painful in the Intel era but I’m on M1 Mac and I’d have a really hard time justifying a request for an upgrade. I absolutely detested my old Intel MacBook (touchbar era) and couldn’t wait to get rid of it.

I run bloated slow electron apps and chrome all day, generally with profligate usage patterns, and things hardly ever slow down even with corporate antimalware. Sometimes I forget about having left Windows VMs running in the background.

Anyway, why would my company spend $2500+ every two years to turn instant into instant?

I'm very surprised you feel it's a given that every SWE at every company has the perk of getting a new machine as quickly as every 2 years, I doubt it's justified by the productivity increases of just 2 years of hardware improvements.
