Hi,

I'm looking for interface statistics for a vhostuser network interface (that uses ovs-dpdk on the other socket side).

The "virsh domifstat <domain> <ifname>" obviously don't works because it looks at "/proc/net/dev" for statistics. When we use vhostuser, we don't create network interface on the host but a socket.

Many tools currently rely on the domainInterfaceStats() API to retrieve this kind of information.

So I would like to known if their is a plan to support ovs as network interface statistics source (with something like "ovs-vsctl get Interface <ifname> statistics") ?

I have started to write a PoC code that fallback to OVS in virNetInterfaceStats() when we don't found the interface in /proc/net/dev.

Does this kind of contribution is welcome/match your plan ?

Yes, if there's a way to gather the equivalent data with OVS, patches for that would be welcome.
