From e08b96371625aaa84cb03f51acc4c8e0be27403a Mon Sep 17 00:00:00 2001 From: Carsten Otte Date: Wed, 4 Jan 2012 10:25:20 +0100 Subject: KVM: s390: add parameter for KVM_CREATE_VM This patch introduces a new config option for user controlled kernel virtual machines. It introduces a parameter to KVM_CREATE_VM that allows to set bits that alter the capabilities of the newly created virtual machine. The parameter is passed to kvm_arch_init_vm for all architectures. The only valid modifier bit for now is KVM_VM_S390_UCONTROL. This requires CAP_SYS_ADMIN privileges and creates a user controlled virtual machine on s390 architectures.
