RE: [Xen-users] Re: How to Networking Bridge?

[Helder Rossa <rossa@xxxxxxxxx>]

You are saying that the real transfer rate will be the one that the real device will have. rigth? 
What do I need to configure to emulate the realtec?

Is it possible to pass a physical device to the VM not an emulated?
If could be possible to assign a real device to the VM then no bridge, routing or nat would be necessary. right?


thanx

>     That doesn't really matter. It's just a VIRTUAL network card anyways, so you're not going to be limited by the "10Mbps" in any real way... It's just part of the emulation of the network card that uses a pretty basic PCNet32 device, which doesn't say 100Mbps or 1Gbps... It wouldn't be very hard to change that, but what's the point - it never hits any real hardware, so whatever the number reported, it's not actually reflecting anything real. Having said all that, the latest QEMU version (in xen unstable) also supports a couple of new network cards, including a 100Mbps realtek 8139. Not that it will make much of a difference to the ACTUAL transfer rate tho'.
