hm .. as i see it, it doesnt look like a vnstat bug to me. on 32bit
maybe you have other corrupted data, because of the buffer overflow you
dont notice it.
i definitely wouldnt come to that idea to monitor guests on guests w/
vnstat because even if it had worked perfectly, its still just a
fictional ethernet device. maybe a vmware monitoring software would be
more precise or an alternative would be to bind each to a virtual
network card and do the monitoring on the host measuring only the
output data and then routing all this devices out, thereby using the
host as a router, which is of course a more complicated setup and i am
not even sure if it would work, but thats the way i would try to build
it up.
