paschke VS jailhouse

This is a pretty cool find! I feel inclined to share my project from a while ago, where the idea was (inspired by Dockerfiles) to automate the building of a working Windows 98 installation in QEMU.

It's fairly janky and slow, but it does what it promises and starting from usual installation media will produce a HDD image with Windows 98 installed and somewhat customised (containing some files I wanted and a custom desktop wallpaper and such).

You could run it inside something like jailhouse hypervisor (https://github.com/siemens/jailhouse) if you want to give it direct dedicated "baremetal" access to hardware. You could do this inside of a buildroot linux image. This would need a customized simulator.

Yes indeed, and Siemens even has their own hypervisor: https://github.com/siemens/jailhouse

Yeah, I think that is what something like https://www.toradex.com/computer-on-modules/apalis-arm-family/nxp-imx-8 is useful for, where it has a separate core. Or even on linux you can use isolcpus to get pseudo-isolation. There are also hardware hypervisors like Jailhouse (https://github.com/siemens/jailhouse) which can completely isolate hardware resources and I suppose might prevent the GPU from causing an issue with realtime task. But this definitely affects ease-of-use and probably requires a reduced feature set in the language (no dynamic allocations) and lots of unsafe code.
