Add <iothreads> line in CPU Pinning section #13

Closed chironjit closed 3 years ago

chironjit commented 3 years ago

In the CPU Pinning section for Performance related guides, the XML settings are missing the <iothreads>1</iothreads>

This is the current indicated:

<vcpu placement="static">12</vcpu>
<cputune>
    <vcpupin vcpu="0" cpuset="6"/>
    <vcpupin vcpu="1" cpuset="18"/>
    <vcpupin vcpu="2" cpuset="7"/>
    <vcpupin vcpu="3" cpuset="19"/>
    <vcpupin vcpu="4" cpuset="8"/>
    <vcpupin vcpu="5" cpuset="20"/>
    <vcpupin vcpu="6" cpuset="9"/>
    <vcpupin vcpu="7" cpuset="21"/>
    <vcpupin vcpu="8" cpuset="10"/>
    <vcpupin vcpu="9" cpuset="22"/>
    <vcpupin vcpu="10" cpuset="11"/>
    <vcpupin vcpu="11" cpuset="23"/>
    <emulatorpin cpuset="0-3"/>
    <iothreadpin iothread='1' cpuset='4-5,12-17'/>
</cputune>

This is how it should be per your win10.xml config:

<vcpu placement="static">12</vcpu>
<iothreads>1</iothreads>
<cputune>
    <vcpupin vcpu="0" cpuset="6"/>
    <vcpupin vcpu="1" cpuset="18"/>
    <vcpupin vcpu="2" cpuset="7"/>
    <vcpupin vcpu="3" cpuset="19"/>
    <vcpupin vcpu="4" cpuset="8"/>
    <vcpupin vcpu="5" cpuset="20"/>
    <vcpupin vcpu="6" cpuset="9"/>
    <vcpupin vcpu="7" cpuset="21"/>
    <vcpupin vcpu="8" cpuset="10"/>
    <vcpupin vcpu="9" cpuset="22"/>
    <vcpupin vcpu="10" cpuset="11"/>
    <vcpupin vcpu="11" cpuset="23"/>
    <emulatorpin cpuset="0-3"/>
    <iothreadpin iothread='1' cpuset='4-5,12-17'/>
</cputune>

Thank you! I will update the documents accordingly.
