I did, and I had the gkhost service running. I did not install the kernel & 
xen packages. I'm not going to downgrade the kernel & xen on the chance that 
I will get faster performance.

That's my limitation. My Fedora xen server has limited space, so I only put my 
everyday vms there. My test systems are on another computer. Would nfs be any 
faster, in your experience? I'm eventually going to convert this other 
computer (SuSE 10.3) to iscsi when I get a chance.

What I did in the benchmark was to compare qemu to halsign under the same 
conditions. I know I'm not going to get fast performance - it was the 
relative difference I was interested in.

With a 1Gpbs nic, right?

And you have a core 2 duo - I have only a core duo. My iperf test was domu 
client to dom0 listener/server, Iperf is generating the data, so nothing is 
being read off the samba mount vbd, so we are testing the speed of a purely 
software nic, and faster processors will perform better.

Everybody's mileage will vary. You get great results - I don't, all tho it's 
still better than Realtek.

Thanx for taking an interest, tho.
