Hi Simon,

Yes, I think that the virtual slot is necessary in the case.
When I add a definition of a PCI device to an inactive managed domain by 
using xm pci-attach, I'd like to know current PCI device configuration 
of the domain. (e.g. I'd like to know free virtual slot numbers or used 
virtual slot numbers.)

Best regards,
 Kan
