Hi,
virsh -r nodeinfo
CPU model: x86_64
CPU(s): 112
CPU frequency: 4000 MHz
CPU socket(s): 1
[Konstantin] Actually this is not a fault, because of NUMA cells: 2
Core(s) per socket: 28
Thread(s) per core: 2
NUMA cell(s): 2
Memory size: 4144275952 KiB
Same for ‘capabilities’, below doesn’t seem faulty:
<topology sockets='1' dies='1' cores='28' threads='2'/>
<topology>
<cells num='2'>
vdsm-client Host getCapabilities
"numaNodes": {
"0": {
"cpus": [
[Konstantin] Fault because there is no numaNodes: { 1 …
And it is interesting that CPUs start with 56 for numaNode 0 (compare it with
NUMA node0 CPU(s) of lscpu)
"cpuSockets": "1",
Fault: "cpuSockets": "1" and not "cpuSockets": "2"
However "cpuThreads": "112" and list in "onlineCpus": is correct.
BR,
Konstantin

Hi, Konstantin.
Thank you for the fast reply.
On oVirt... New Virtual Machine -> Host -> Configure NUMA is currently disabled
but I still don't understand why oVirt doesn't identify the 2 sockets.
I'll do some more research and install version 4.5. I am currently using
version 4.4.10.
Below are the output of the commands:

Hi,
could you check
sudo vdsm-client Host getCapabilities
virsh nodeinfo
virsh capabilities
and possibly see the issue?
By the way most likely I think you will see CPU socket(s): 1 in virsh
nodeinfo, but with NUMA cell(s): 2
(that will be OK)
BR,
Konstantin

Betreff: [ovirt-users] Re: Processors compatibility matrix oVirt
Sorry, I mentioned it wrong. The engine VM is ok. What happens is that the
lscpu output of the physical host is different from the host information in
oVirt.
lscpu:
CPU(s): 112
On-line CPU(s) list: 0-111
Thread(s) per core: 2
Core(s) per socket: 28
Socket(s): 2
NUMA node(s): 2
Vendor ID: GenuineIntel
BIOS Vendor ID: Intel(R) Corporation
CPU family: 6
Model: 85
Model name: Intel(R) Xeon(R) Platinum 8276M CPU @ 2.20GHz
Ovirt -> Compute -> Hosts:
CPU Model Name: Intel(R) Xeon(R) Platinum 8276M CPU @ 2.20GHz
CPU Type: Secure Intel Cascadelake Server Family
CPU Sockets: 1
CPU Cores per Socket: 56
CPU Threads per Core: 2 (SMT Enabled)
TSC Frequency: 2199999000 (scaling enabled)

Jorge,
Your 8276 processor belongs to the former Cascade Lake Family (server), which
is supported by oVirt (listed as Intel Cascadelake Server Family).
For CPU requirements see:
https://www.ovirt.org/documentation/installing_ovirt_as_a_standalone_manager_with_remote_databases/#CPU_Requirements_SM_remoteDB_deploy
In Linux, you can see the number of sockets with: grep "physical id"
/proc/cpuinfo | sort -u | wc -l
Not sure how you installed your oVirt engine, but with hosted-engine, oVirt
installs with 1 virtual socket and in advanced options can be change to 2 or 4.
Cheers!
... Dean
