Indeed, that sounds useful, and it is strictly additive so there is no
technical reason preventing that addition.
Along the same lines, I am considering adding numacell memory
information to this output. Some options for formatted output would
be:
<topology>
<cells num='2'>
<cell id='0' memoryKB='8386504'>
<cpus num='8'>
<cpu id='1' sibling='9'/>
.
.
</cpus>
</cell>
</cells>
</topology>
or, more similar to the guest xml
<topology>
<cells num='2'>
<cell id='0'>
<memory unit='KiB'>8386504</memory>
<cpus num='8'>
<cpu id='1' sibling='9'/>
.
.
</cpus>
</cell>
</cells>
</topology>
There are a lot of options here for how to format the output. I don't
anticipate the unit of KiB to change since that is what is in the
/sys/devices/system/node/node0/meminfo files.
Thoughts?
