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.

Support hosting paravirtualized guest machines using the SIE

virtualization capability on the mainframe. This should work

on any 64bit machine.

This module provides access to the hardware capabilities through

a character device node named /dev/kvm.

To compile this as a module, choose M here: the module

will be called kvm.

If unsure, say N.
