Hello again,
I want to thank you for the information given. Now I understand what you
mean, I'm going to test virtio drivers with the last kernel possible.
Thanks a lot.
Regards,
Miguel

Hey Miguel,
what Haydn meant was to force qemu to *emulate* a e1000 NIC
instead of the default RTL8139. That emulation is done by qemu in
userspace and has absolutely nothing to do with your physical NIC
por the bridge.
Chosing a NIC is done with the "model=" parameter.
kvm -net nic,model=e1000
Even better performance-wise would be to use the new virtio
interface which paravirtualizes your physical NIC instead of
emulating one.
For that, use:
kvm -net nic,model=virtio
Of course you'll need to install the corresponding drivers in your
guest. The e1000 should be supported in every guest and for the
virtio interface there are windows guest drivers (see the
kvm-announce mailing list for that) as well as linux guest drivers
included in kernel 2.6.25 upwards.
By the way: This is good stuff f you're interested in hard disk
performance, too: http://kvm.qumranet.com/kvmwiki/Virtio
