Does Virtualbox support libvirt? If so, you can compile the Host sFlow
agent to link to the libvirt library to obtain VM statistics.
Otherwise, if there is a Virtualbox specific performance library that can
be used to retrieve metrics (Host sFlow uses libxenstat for Xen and WMI for
Hyper-V) then it shouldn't be too hard to write an adapter.
The best place for questions on the Host sFlow agent is the mailing list,
https://lists.sourceforge.net/lists/listinfo/host-sflow-discuss
