Hi, everyone
I'm writing a application using libvirt and need to query guest os's virtual network interface usage, like bytes read or written through a given interface. I know int virDomainInterfaceStats(virDomainPtr dom, const char * path, virDomainInterfaceStatsPtr stats, size_t size) is designed for my purpose but I 'm not sure how I determine the second parameter path. I'm now think of determining the virtual interface by parsing the domain's xml configure file. But I don't find that libvirt supply such functions, that means, I have to resort to other library lik libxml?
You may be interested in the libvirt-glib project, which includes the libvirt-gconfig subpackage to provide an API on top of libvirt for more convenient access into domain XML: https://www.redhat.com/archives/libvirt-announce/2012-March/msg00004.html -- Eric Blake eblake@redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
