Note that this has an user-visible side-effect: instead of reporting "KVM is not supported for this target", QEMU binaries not supporting KVM will report "kvm accelerator does not exist". As kvm_availble() always return 1 when CONFIG_KVM is enabled, we don't need to set AccelClass.available anymore. kvm_enabled() is not being completely removed yet only because qmp_query_kvm() still uses it. This also allows us to make kvm_init() static. Reviewed-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
