By default, when using the QEMU -kernel command line argument, virt machines boot into NS/SVC. When using the QEMU -bios command line argument, virt machines boot into S/SVC. The secure state can be changed from the default specifying the secure state as a machine property. For example, the below command line would enable secure state on a -linux boot: aarch64-softmmu/qemu-system-aarch64 -machine type=virt,secure=on -kernel ...
