One of the killer features of Qubes when I used it was the ability to "pause" a VM and all of the apps running in it. That's something I've tried to replicate with tools like tmuxp but I've never found an abstraction as clean as "serialize the whole process tree to disk" like Qubes has.
I gave up on it for usability reasons, but that feature is killer. Anybody else aware of anything similar?
The amount of hidden state modern hardware uses is humongous, it's infeasible without abstracting it in a VM. I remember some Win9x software that would let you save the process state to disk and restore it later, but even in that much more primitive era it was hit and miss.

There used to be cryopid in the days of 32 bit x86 and it was great and Bernard is cool.

Somehow I doubt it's still a thing but haven't had a reason to check.

Look at https://criu.org/Main_Page - it's meant for exactly that, though the problem space is genuinely hard.
What is your use-case for it? Hibernation?
