I'm not familiar with qemu:( On native OS, admin could trigger PCI device hotplug operations through /sys/bus/pci/slot/xx/power. Not sure whether that's needed for guest OS too.
Why is it needed on physical HW? May be it is needed in a VM for the same reason?
As Amos has mentioned, it's used power on/off a PCI device instead of physical hotplug. Not sure whether it's needed in guest OS. --gerry
