I just had the same problem: While setting up a new debian domU I was wondering why the network was so slow just on that vm. I noticed that there was a burst of traffic every now and then. First I thought - like Roberto - it was a scheduling problem. But your comment caused me to check the MAC address of that machine and it was in fact the same like on another vm *silly me*. > > On May 6, 2011, at 12:38, Roberto Bifulco <roberto.bifulco2@xxxxxxxx > <mailto:roberto.bifulco2@xxxxxxxx>> wrote: > >> Some more infos! >> I run a simple ping test from my laptop to both domUs runinng on my >> server.
