Hi,
Libvirt provides the disk and Network interfaces statistics for each
of the guests configured. Is there a api which tells me how many disk
and network interface are configured per guest so that can make the
corrosponding calls to get the statistics of each the disk/nic (like
virDomainBlockStats and virDomainInterfaceStats).
Thanks,
Vadiraj

Get the Domain XML and analyze it, see:
http://libvirt.org/html/libvirt-libvirt.html#virDomainGetXMLDesc
and
http://libvirt.org/format.html

In addition to DV's answer, this is how it's done in virt-top:
http://hg.et.redhat.com/virt/applications/virt-top--devel?f=31e1a2bb21e4;...
(It'd be a lot easier if I'd had an XML library available with XPath
support...)
If you want some C code which does this using libxml2 and XPath, then
take a look at my virtstats module in the collectd source
(http://collectd.org/).
Because trawling through the XML is rather inefficient, virt-top only
does it once for each new domain it sees, so if interfaces are added or
removed then you have to restart virt-top. For collectd it rechecks the
XML every 60 seconds IIRC.
