Re: [libvirt] vnet<X>'s & interfaceStats().. KVM device numbering confusion?

This leaves me scratching my head a little bit, say I have a domain which has ended up with ID = 8, but may for instance have network 'vnet1' associated with it. I'm not sure how I can determine any association between the domain & which interface belongs to it! (e.g. a call to domain.interfaceStats() requires the correct network interface as a parameter).

  Ask libvirt for the XML config while the domain is running, you should
see the interface there I think, try "virsh dumpxml 8"
