[pve-devel] Disks hotplug patchs

[Alexandre DERUMIER]

I think I can do better, i'm reading libvirt code and  "drive_del" return error code if something goes wrong guest side.

I'll add a check.

If you try to unplug a disk in use , mounted by exemple , the unplug will fail. 

Device is not remove, that's why I parse the "info pci" output. 

I the device is always present after the unplug , I sent a die "error on hot-unplugging device" .

What happens when we hot-unplug a disk device? If the disk is still in use by the VM? 
Does that crash the linux kernel?
