I'm using command-line arguments, not libvirt. A quick Google suggests that
you need to define a number of iothreads in the XML and them assign them to
the drivers, like:
<domain>
...
<iothreads>1</iothreads>
...
<disk type="block" device="disk">
<driver name="qemu" type="raw" cache="none" io="native" iothread="1"/>
...
</disk>
...
</domain>
It's pretty much the XML equivalent of what you'd write on the command-line.
Regards,
