You can explain in this case means that the field "Total Cores " and "CPU Sockets"  in the menu to create a new virtual machine (cpu.png)?

Hi

I set up two nodes running ovirt.
The configuration of both servers is identical (node.png).
when you create a virtual machine to a setting is per (vm.png). It runs successfully.
If the setting "Number of CPU Cres," set to 3 (1 Socket (s), 3 Core (s) per Socket) (fail.png) - VM will not start. ovirt error:
“Cannot run VM. There are no available running Hosts with enough cores in VM's Cluster.”
Why not?




You cannot run a VM with more sockets than the host's cores.
Y.





Do I understand correctly that the value of (1 Socket (s), 3 Core (s) per Socket) means 3 virtual CPU on a physical processor core nodes?
Number of CPU Cres: 2 (2 Socket (s), 1 Core (s) per Socket) - the virtual machine is started successfully
Number of CPU Cres: 4 (2 Socket (s), 2 Core (s) per Socket) - error.
Number of CPU Cres: 2 (1 Socket (s), 2 Core (s) per Socket) - the successful launch
