static TypeInfo kvmclock_info = {
.name = "kvmclock",
.parent = TYPE_SYS_BUS_DEVICE,
It seems to be linked from here
.instance_size = sizeof(KVMClockState),
.class_init = kvmclock_class_init,
};
I also checked other devices which can be seen in the output of
qom-list. I have not seen kvmclock QOM is different from other
devices.
So i am very surprised that why kvmclock device can not be seen in
qom-list output.

Yeah, i can see it in qom-list output.
