Hello Péter,

A slight correction there.  The virtual network card identifies itself 
to the guest OS as an 10Mbps PCNet (so that the guest can use it without 
needing special drivers), but in fact it runs as fast as your system 
allows.  For example, scp from a Debian 3.1 guest to my host system and 
vice-versa gives me around 5 MByte/s (just a quick test, may depend on 
the guest).

Regards,

Michael
