@foone I've done something very similar accidentally (and boy was that confusing to debug), should be pretty easy

Making it follow the same failure patterns as real hardware might be tricky, but random stuck bits should be straightforward

@foone Just run qemu on a machine with bad ram

@foone That reminds me of FAUmachine. A university research project with focus on fault injection into VMs. Haven't looked at their stuff in uhhh, 2 decades though. 😅

@foone Looks like you can used options like memory-backend-file to make qemu use shared memory for all of the VM's memory? Then you should be able to mutilate the memory from another process?

@foone searching "qemu fault injection" finds a number of relevant papers

@foone That’s a fun idea.
