Hi,
I cannot add iothreads (https://libvirt.org/formatdomain.html#elementsIOThreadsAllocation) in the libvirt xml configuration file. Once I add "<iothreads>4</iothreads>" and other related config for IOthreads into the libvirt xml configuration file with virsh command and save it, these iothreads related configuration will disappear after I open libvirt xml configuration file again for double-check.
If XML disappears after saving it, this usually indicates that either you made a mistake and used the wrong XML element or in the wrong place, or that your libvirt version is too old to support it. You can use the virt-xml-validate too to verify your XML file against the schema for your installed version of libvirt, which will report any errrors.
virt-xml-validate has no help. Let me try libvirt 2.5.0 and QEMU 2.7.0. Thank you. Best, Weiwei Jia
