Can somebody knows how to enable virtio-scsi-data-plane in libvirt for
specific domain?
I know that i need to replace "-device virtio-scsi-pci" with "-object
iothread,id=io1 -device virtio-scsi-pci,iothread=io1" in qemu, but how
can i do this in libvirt?

Check out virsh iothread{info|pin|add|del} and of course the
corresponding virDomain{Add|Pin|Del}IOThread and virDomainGetIOThreadInfo.

Yes, thanks! Does in near feature libvirt devs integrate this ability
to domain format? As i understand all qemu stable features supported
by libvirt. And data plane for virtio-blk is stable for some time....

Such as?
http://libvirt.org/formatdomain.html#elementsIOThreadsAllocation
and usage within <cputune> as <iothreadpin> or <iothreadsched>

So you mean that if i define iothread in domain xml and create
virtio-scsi it automatic enables virtio-scsi-data-plane?

As long as the qemu you're using supports the "-object iothread", then
this works. I forget the exact version it went into qemu.

Nice! Thanks! (i'm use latest qemu) how can i check that data-plane
used by virtio-scsi ?

oh - um... Hold that thought...
*scsi* not yet supported (I think changes only recent went into qemu,
but it hasn't been on my list of things to follow closely.
*pci* is supported
Gotta read more closely sometimes...
