Possible values are 10 100 & 1000 Mb, and are configured independently of the driver/model of NIC. I haven't tested it yet, and since discovering this detail, have been somewhat disheartened at the thought of ~8 Gb vhost throughput being throttled by the highest possible link speed setting being 1000 Mb. So maybe plan b could be to install a test router just for that function, and loop through it. -C On Sat, 20 Nov 2010 10:39 -0500, "Javier Guerra Giraldez" <javier@xxxxxxxxxxx> wrote: > On Sat, Nov 20, 2010 at 3:40 AM, Thomas Mueller <thomas@xxxxxxxxxxxxxx> > wrote: > > maybe one of the virtual network cards is 10mbit? start kvm with "-net > > nic,model=?" to get a list. > > wouldn't matter. different models emulate the hardware registers > used to transmit, not the performance. > > if you had infinitely fast processors, every virtual network would be > infinitely fast. > > -- > Javier > -- > To unsubscribe from this list: send the line "unsubscribe kvm" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html > -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
