This reverts commit c96bd78e4e71c799dc391566fa9f0652dec55dca. So our code is one big mess and we modify domain definition while building qemu_command line and our hotplug code share only part of the parsing and command line building code. Let's revert that change because to fix it properly would require refactor and move a lot of things.
