[Qemu-devel] [PATCH 0/2] Disable kvm_mmu_op by default on pc-1.4

[Eduardo Habkost]

The kvm_mmu_op feature was removed from the kernel since v3.3 (released
in March 2012), it was marked for removal since January 2011 and it's
slower than shadow or hardware assisted paging (see kernel commit
fb92045843). It doesn't make sense to keep it enabled by default.

Also, keeping it enabled by default would cause unnecessary hassle when
libvirt start using the "enforce" option.

  target-i386: don't set any KVM flag by default if KVM is disabled
  target-i386: disable kvm_mmu_op by default on pc-1.4
