Thanks Wangkai but libvirt infact pre-configures network tap devices and pre-opens /dev/vhost-net file and passes these to qemu as open, ready to use file descriptors. My issue is that my qemu requires that /dev/vhost-net directory is removed and it's kernel module be unloaded. Then it creates a vhost -net device using its own configuration.

Currently in the VM XML, I am passing the following command line argument as a passthrough argument: -netdev type=tap,id=net1,script=no,downscript=no,ifname=port3,vhost=on -device virtio-net-pci,netdev=net1,mac=00:00:00:00:00:01,csum=off,gso=off,guest_tso4=off,guest_tso6=off,guest_ecn=off Is there another way to represent this in the XML file? maybe that may solve the problem.

Hi Michal, What I found was that when I restarted the machine and did a virsh edit command to see the xml config, I see that it is was not actually changed. This suggests why I saw 256 again after restarting. So now I tried again to edit the xml via virsh edit command and used the following to set the parameters. <driver name='qemu' txmode='iothread' ioeventfd='on'

OK, here's a patch that implements the virtio spec update that I sent earlier. It supercedes the PUBLISH_USED_IDX patches I sent out earlier. Support is added in both userspace and vhost-net. If you see issues or are just curious, you can turn the new feature off. For example: -global virtio-net-pci.event_idx=on -global virtio-blk-pci.event_idx=off Also, it's possible to try both
