Introduce hotplug methods (hypervisor inteface)
4 new methods: HotAddDevice, HotDelDevice, HotModDevice, HotplugSupported
All these are the hypervisor interface with the backend.
In general they read current runtime info, do the actual hotplug
and update the runtime file.
NIC hot-add:
- open a tap and get its file descriptor.
- pass fd with SCM rights (using python-fdsend) via monitor socket
- create netdev and device with id=kvm_devid and proper pci info
Disk hot-add:
- create drive with id=kvm_devid
- create device with id=kvm_devid and corresponding pci info
Use MonitorSocket in _PassTapFd in order to connect to monitor socket
and pass the tap's file descriptor using fdsend.
