> Build fails if HOTPLUG is disabled

OK thanks for reporting.
Actually there is no good reason to disable hotplug on Linux.
Though it means that it's impossible to build on FreeBSD.

Tetsuya, the right fix is to remove this option.
You should manage to graceful degrades hotplug in not supported
cases supported: devices cannot be detachable in case of VFIO or nic_uio.
What about uio_pci_generic?
