This is a follow up to my previous series to get us started in the QOM
direction. A few things are different this time around. Most notably:
1) Devices no longer have names. Instead, path names are always used to
identify devices.
2) In order to support (1), dynamic properties are now supported.
3) The concept of a "root device" has been introduced. The root device is
roughly modelling the motherboard of a machine. This type is a container
type and it's best to think of it as something like a PCB board I guess.
To try it out, here's an example session:
Launch:
anthony@titi:~/build/qemu$ x86_64-softmmu/qemu-system-x86_64 -hda
~/images/linux.img -snapshot -device virtio-balloon-pci,id=foo -qmp
unix:/tmp/server.sock,server,nowait
