[ovirt-users] CPU Pinning topology

2019-11-06 Thread Fabrice Bacchella
I'm trying to understand the field "CPU Pinning topology" in the "Ressource 
Allocation" tab, that looks it needed by High Performance VM.

I have this hardware:

# lscpu 
Architecture:  x86_64
CPU(s):48
On-line CPU(s) list:   0-47
Thread(s) per core:2
Core(s) per socket:12
Socket(s): 2
NUMA node(s):  2

And I want to run a 22 vCPU vm on it, so no SMT, and 11 vCPU mapped to each 
socket.

The only explanation I found about this field content was here:
https://rhv.bradmin.org/ovirt-engine/docs/Virtual_Machine_Management_Guide/appe-Reference_Settings_in_Administration_Portal_and_User_Portal_Windows.html#Virtual_Machine_Resource_Allocation_settings_explained

and I can wrap my head around it. Do I need to given explicit mapping for all 
the 22 vCPU ? And dig in lscpu -e or numactl -H to find how each pCPU is 
identified ?___

 cpu pinning Hello,
 
 how can I test if cpu-pinning is working.

Hi Wolfgang,
In the create or edit VM dialog,there's a text box allowing you to
specify a pinning topology, as you can see in:
http://www.ovirt.org/Features/Design/cpu-pinning#UI

The idea is to specify physical#virtual mapping, and more if needed:
p1#v1_p2#v2...

Also, if needed range and negation are also supported:
p1#Va-Vh,^Vb
