alt Hacker News>Being able to snapshot and restore memory is a pretty common feature across all decent hypervisors
A hypervisor that protects against this already exists for Linux with Android's pKVM. Android properly enforces isolation between all guests.
Desktop Linux distros are way behind in terms of security compared to Android. If desktop Linux users ever want L1 DRM to work to get access to high resolution movies and such they are going to need such a hypervisor. This is not a niche use case.
It "protects" against this given the user already does not control the hypervisor, at which point all bets are off with regard to your rights anyway. It's actually worse than Windows in this regard.
I would never use a computer I don't have full control over as my main desktop, especially not to satisfy an external party's desire for control. It seems a lot more convenient to just use a separate machine.
Even mainstream consumers are getting tired of DRM crap ruining their games and movies. I doubt there is a significant Linux users would actually want to compromise their ownership of the computer just to watch movies or play games.
I do agree that Linux userland security is lackluster though. Flatpak seems to be a neat advancement, at least in regard to stopping things from basically uploading your filesystems. There is already a lot of kernel interfaces that can do this like user namespaces. I wish someone would come up with something like QubesOS, but making use of containers instead of VMs and Wayland proxies for better performance.
