[libvirt] libvirt and physical hardware devices

Greetings. I am interested in finding out what kinds of physical hardware data can be pulled out of libvirt at present. In particular, I'm interested in sourcing: 1. All the processor information that would be revealed from /proc/cpuinfo -cpu # -core # -# cores total -model -family -cpuid_lvl -speed -cache -vendor -flags 2. The following network device paramters: -interface name -mac address -current ip address -current netmask -current broadcast -current link bandwidth This post (https://www.redhat.com/archives/libvir-list/2009-June/msg00236.html) seemed promising at least wrt. network stuff, and I was wondering if it ever went anywhere. So my overall questions: 1. Is this data (specifically, all of it) tracked and exposed by libvirt at present? 2. If not, are there any plans to do so? I know it is possible to find out this data using /proc/cpuinfo and the various socket ioctls, but would like to avoid relying on those if possible. Thanks, -Arjun Roy
