In the current libvirt PCI code, there is no checking whether a PCI device is in use by a guest when doing node device detach or reattach. This causes problems when a device is assigned to a guest, and the administrator starts issuing nodedevice commands. Make it so that we check the list of active devices when trying to detach/reattach, and only allow the operation if the device is not assigned to a guest.

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
