Maybe qemu 2.2 optimisations ? If you don't have change vm config file, this
can be the only explain.

But that don't mean that physically, the virtual cpus|numa nodes will be
mapped to correct physical cpus.
Many thanks for your reply, and please, let me to do a question:

Hi,
As i have running a VM with MS-SQL Server (and with 246 GB RAM exclusive

MS-SQL Server), the DBA of M
with only 1vm, you can try to manually map virtual nodes to specific

I'm interested to see results between both method (Maybe do you want last

I plan to add gui for part1.

I think it could work with:
source host numa:
-object memory-backend-ram,size=1024M,policy=bind,host-nodes=0,id=ram-node0
-numa node,n
This add numa topology support
numa:
on: only expose numa to guest
other values : bind memory to host numa nodes
example:
---
sockets:4
cores:2
memory:4096
numa: bind
qemu command line for values != on
--
-object memory-backend-ram,size=1024M,policy=bind,hos
t NUMA nodes: Invalid argument
if the host node is not numa
(can be check easily with -d /sys/devices/system/node/node$i/)
