This patch adds XML definitions for guest NUMA specification and contains
routines to parse the same. The guest NUMA specification looks like this:
<cpu>
...
<topology sockets='2' cores='4' threads='2'/>
<numa>
<cell cpus='0-7' memory='512000'/>
<cell cpus='8-15' memory='512000'/>
</numa>
...
</cpu>
Hi Bharata,
I realise I'm a bit late on this, but I'm just catching up on the list
traffic.
Firstly why is the XML tag called "cell", it seems to represent what we
would normally call a "node" in terms of NUMA?
Also does the parser support disjoint ranges for cpus and memory? Or do
we not need that complexity for some reason?
For example what if I have a topology that looks like:
Node 0:
CPUs: 0-3,8-11
MEM : 0-1G,2G-3G
Node 1:
CPUs: 4-7,12-15
MEM : 1G-2G,3G-4G
cheers
