Hi Mike, I'm not sure about the status of libvirt support for virtio-scsi options but in the meantime you can use qemu:commandline passthrough: http://blog.vmsplice.net/2011/04/how-to-pass-qemu-command-line-options.html Stefan Thanks Stefan, My plan is to write the support in OpenStack, which unfortunately does not accept patches doing qemu passthrough: http://lists.openstack.org/pipermail/openstack-dev/2013-November/018551.html -- Mike Perez -- libvir-list mailing list libvir-list@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list

The higher you go in the stack, the simpler configuration should be in my opinion. For openstack, I think all you need is a singlequeue vs. multiqueue knob (setting num_queues = # VCPUs for multiqueue).

I'm not aware of anyone else who is currently working on it, so anyone please jump right in...
