For a physical network card, it has a maximum transmission speed such as
100Mb. How about network in a virtual machine? It is a virtual network
card. Is there any speed limit? Or it can transmit as fast as possible? If so, I guess network transmission happened within a physical host should be very fast (great than 100Mb). But this is not true in my experiment.

Out of curiousity, what kind of testing have you run, and what kind of speeds are you getting?

I've got a configuration with DomU talking to Dom0 over a vif, and seem to be seeing UDP losses, even at low data rates. (I haven't dug into this deeply to very the problem yet, though.) So I'd be interested if you're seeing something similar.

Thanks,
mukesh
