Notes - notes.io

Here is an example from a 20core firestone using the newly supported numatune section, just adjust the cpus and mem as needed based on the 'numactl -H' layout in the host:

*** first pin each guest vcpu to a set of host cpus for each numa node:

<memory unit='KiB'>498073600</memory>
<vcpu placement='static'>160</vcpu>
<cputune>
<vcpupin vcpu='0' cpuset='0,8,16,24,32,40,48,56,64,72'/>
<vcpupin vcpu='1' cpuset='0,8,16,24,32,40,48,56,64,72'/>
<vcpupin vcpu='2' cpuset='0,8,16,24,32,40,48,56,64,72'/>
{...}
<vcpupin vcpu='79' cpuset='0,8,16,24,32,40,48,56,64,72'/>
<vcpupin vcpu='80' cpuset='80,88,96,104,112,120,128,136,144,152'/>
{...}
<vcpupin vcpu='158' cpuset='80,88,96,104,112,120,128,136,144,152'/>
<vcpupin vcpu='159' cpuset='80,88,96,104,112,120,128,136,144,152'/>
</cputune>

*** and create numa nodes ("cells") in the guest:

<cpu mode='host-passthrough'>
<topology sockets='2' cores='10' threads='8'/>
<numa>
<cell id='0' cpus='0-79' memory='249036800' unit='KiB'/>
<cell id='1' cpus='80-159' memory='249036800' unit='KiB'/>
</numa>
</cpu>

*** In the <numa> section, the 'cpus' are the guest vcpus you want in each numa node in the guest, evenly divide the total guest mem between the numa nodes, then pin those guest cells to each host numa node as needed, ex:

<numatune>
<memnode cellid='0' mode='strict' nodeset='0'/>
<memnode cellid='1' mode='strict' nodeset='8'/>
</numatune>

*** here 'cellid' is the guest cell id you created above, and 'nodeset' is the host numa node you want to pin it to
