Secure Execution is a confidential computing technology on s390x (IBM Z & LinuxONE). Enable the correspondent virtualization technology in QEMU (where it is referred to as "Protected Virtualization"). - Introduce enableProtection and appendProtectionDevice functions for QEMU s390x. - Introduce CheckCmdline to check for "prot_virt=1" being present on the kernel command line. - Introduce CPUFacilities and avilableGuestProtection for hypervisor s390x to check for CPU support.
