Don't we need to precise x86 and arm here?
Well I got inspired of intel_iommu doc. I think this is sufficiently
precise, no?
Apparently not:
$ git grep -w '"virt"' hw
hw/arm/virt.c:96: mc->alias = "virt"; \
hw/m68k/virt.c:314: .name = MACHINE_TYPE_NAME("virt"),
hw/openrisc/virt.c:37:#define TYPE_VIRT_MACHINE MACHINE_TYPE_NAME("virt")
hw/riscv/virt.c:1754: .name = MACHINE_TYPE_NAME("virt"),
hw/xtensa/virt.c:127:DEFINE_MACHINE("virt", xtensa_virt_machine_init)
