Check if hotplug is supported in CheckPrereq

Introduce new RPC hotplug_supported that invokes the corresponding
hypervisor's method which checks if hotplug is generally
supported. Call this RPC early in CheckPrereq() and abort if
hotplug is not supported. Currently only KVM hypervisor with...

drive_del after device_del in disk hot-remove

This is needed so that qemu process really releases the

Some fixes in _GenerateKVMBlockDevicesOptions()

  • Add docstring.
  • fix missed usecase of boot_disk=False if kernel_path is given.
  • Use devlist arg in GenerateKVMBlockDeviceOptions()
    This is previously calculated in _ExecuteKVMRuntime()
    so there is no need to rerun the same command....

Introduce hotplug methods (hypervisor inteface)

4 new methods: HotAddDevice, HotDelDevice, HotModDevice, HotplugSupported
All these are the hypervisor interface with the backend.

Hepler methods for PCI slots and device ids

Device naming:
QEMU monitor expects devices to be uniquely named. Device ids derive
from the following function:
kvm_devid = <device_type>-<part of uuid>-pci-<pci_slot>
Device ids must be reproduce-able when we want to remove them....
