Hi Klaas, in our case, the Hypervisor CPU looks like this:
CPU(s): 32 On-line CPU(s) list: 0-31 Thread(s) per core: 2 Core(s) per socket: 8 Socket(s): 2 NUMA node(s): 2 NUMA node0 CPU(s): 0-7,16-23 NUMA node1 CPU(s): 8-15,24-31 The PROD VM should have 24 PINNED (due to licensing requirements) vCPUs out of the 32 threads and around 838G of the 1 TB RAM. The TEST VM should have 8 vCPUs out of the 32 threads and around 128G of 1 TB RAM. With these PROD VM Requirements, it does not make sense to limit vCPUs to one socket / NUMA node. The TEST VM can be limited to one socket. I guess I have made these mistakes: - I should not use Physical CPU thread 0 but leave it for Hypervisor - I have configured the VM "2 threads per core" with <topology sockets='16' cores='6' threads='2'/>, but have not specified two threads for each vCPU in the pinning field. In the oVirt "Resource Allocation" Tab in "CPU Pinning Topology", i have specified: 0#8_1#9_2#10_3#11_4#12_5#13_6#14_7#15_8#16_9#17_10#18_11#19_12#20_13#21_14#22_15#23_16#24_17#25_18#26_19#27_20#28_21#29_22#30_23#31 The Calculate CPU Pinning script from the RHV HANA Guide results in this mapping: 0#1,17 1#1,17 2#2,18 3#2,18 4#3,19 5#3,19 6#4,20 7#4,20 8#5,21 9#5,21 10#6,22 11#6,22 12#9,25 13#9,25 14#10,26 15#10,26 16#11,27 17#11,27 18#12,28 19#12,28 20#13,29 21#13,29 22#14,30 23#14,30 But with this approach, I can not separate CPUs between PROD VM and TEST VM. Any ideas? _______________________________________________ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/PF7UCDGZPL3FJ4O5XBICJNSJKOM2ALBE/
