The current machine type in QEMU (i.e. "virt") is renamed to "virt-2.6", whose naming scheme is similar to other architectures. For the purpose of backward compatibility, "virt" is converted to an alias, pointing to "virt-2.6". With this patch, "qemu -M ?" lists the following virtual machine types along with others: virt QEMU 2.6 ARM Virtual Machine (alias of virt-2.6) virt-2.6 QEMU 2.6 ARM Virtual Machine Signed-off-by: Wei Huang --- hw/arm/virt.c | 23 ++++++++++++++++++----- 1 file changed, 18 insertions(+), 5 deletions(-) diff --git a/hw/arm/virt.c b/hw/arm/virt.c index 8c6c996..be9bbfb 100644 --- a/hw/arm/virt.c +++ b/hw/arm/virt.c @@ -1345,6 +1345,19 @@ static void virt_set_gic_version(Object *obj, const char *value, Error **errp) } } +static void virt_machine_class_init(ObjectClass *oc, void *data) +{ +} + +static const TypeInfo virt_machine_info = { + .name = TYPE_VIRT_MACHINE, + .parent = TYPE_MACHINE, + .abstract = true, + .instance_size = sizeof(VirtMachineState), + .class_size = sizeof(VirtMachineClass), + .class_init = virt_machine_class_init, +}; + static void virt_instance_init(Object *obj) { VirtMachineState *vms = VIRT_MACHINE(obj); @@ -1382,7 +1395,8 @@ static void virt_class_init(ObjectClass *oc, void *data) { MachineClass *mc = MACHINE_CLASS(oc); - mc->desc = "ARM Virtual Machine", + mc->desc = "QEMU 2.6 ARM Virtual Machine"; + mc->alias = "virt"; mc->init = machvirt_init; /* Start max_cpus at the maximum QEMU supports.
