I use the qemu-kvm patch to your git tree that I posted
a while back (also attached). And it needs your TUNSETVNETHDRSIZE
ioctl in the kernel as well. Also, I added the TUN ioctl
defines to /usr/include for this to pick up (it compiles, but
won't do the ioctl's without that); will get back
to that patch per your comments next.
[also correction: I said 10-20% guest to host, I meant host-to-guest
(ie, the receiver side). h2g appears improved too, but not as
much)]
