I have pushed the rebased QEMU codes and tcm_vhost codes to my git tree.
Perhaps some one is interested in playing with it.

Hi,
As I've mentioned before in the past, I will apply vhost-* without an extremely

fundamental change in the userspace networking interface (with something like VJ
channels), it's extremely

The patchset was developed originally by Stefan about one year ago. I now
rebase it to latest qemu.git/master and fixed some issues to make it work
against tcm_vhost and virtio_scsi driver. But there are still some issues to
fix. Let us make more effort later.
