[ovirt-users] CPU Pinning topology
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 ?___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/LWM2V4ULCHWM74CRLDTYTX6QC3Z6F3FR/

Greetings Wolfgang 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 Doron ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
