Re: [Qemu-devel] Hotplug handler

[Sameeh Jubran]

This is the command line. All of the devices are wired to pci.0, there is
no pci bridge.

According to this,  Integrated Endpoints are not hot-pluggable. However I
can still use device_del to delete a device and device_add to add e1000
with no issues.
