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.

Title:
  Could you set vm.allocate_pgste = 1 by default?

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.
