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....

Hotplug: cmdlib support

Return link_name in blockdev_assemble rpc
