My modprobe.conf solution might not work in all cases, as the kvm module might be loaded on demand by a process accessing /dev/kvm. That process then already has 2k page tables. So I agree with Viktor: If we want to support KVM, maybe set vm.allocate_pgste = 1 unconditionally.

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.
