SR-IOV Pool Availability
If I'm using the SR-IOV Pool assignment method (from
http://wiki.libvirt.org/page/Networking#Assignment_from_a_pool_of_SRIOV_VFs_in_a_libvirt_.3Cnetwork.3E_definition
), how would I check how many virtual functions are already in use?
Is there a method other then looping through all the active guests and
determining if they're using the SR-IOV interface?
