Hi, I was trying to do a "device_del" on my ivshmem device and it won't work unless the device is added via hotplug. If the device is coldplugged (added at startup) then nothing happens. I think I tracked this behaviour to the patch below. Is not allowing coldplugged devices to be unplugged the desired behaviour? Thanks, Cam commit 5beb8ad503c88a76f2b8106c3b74b4ce485a60e1 Author: Isaku Yamahata <yamahata@valinux.co.jp> Date: Mon Sep 6 16:46:18 2010 +0900 pci: call hotplug callback even when not hotplug case for later use. call hotplug callback even when not hotplug case for later use.
