cool. Is there a way to measure vm.allocate_pgste=1 overheads and is it ok to enable by default? It's needed only on vm hosts... maybe i should add it to the qemu package only? or like try to add systemd hackery to only apply it on bare-metal? (well nested virtualisation is supported...)

Status in linux package in Ubuntu: Incomplete Bug description: Hello, to use qemu one needs vm.allocate_pgste = 1, on kernels that support that setting e.g. s390x. I'm now setting it with a sysctl.d snippet in procps package, however I was wondering if it could be set by default. Or not.
