Hi
I set uptwonodesrunningovirt. The configuration ofboth serversis identical (node.png). when you create avirtual machine toasetting is per(vm.png). It runssuccessfully. Ifthe setting"Number of CPUCres," set to3(1Socket (s),3Core (s) per Socket) (fail.png) - VMwill not start.ovirterror: “Cannot run VM.There are no available running Hosts with enough cores in VM's Cluster.” Why not?
Do I understand correctlythat the value of(1Socket (s),3Core (s) per Socket)means 3virtualCPU onaphysicalprocessor corenodes? Number of CPUCres: 2 (2Socket (s),1Core (s) per Socket) -the virtual machineis startedsuccessfully Number of CPUCres: 4 (2 Socket (s),2Core (s) per Socket) -error. Number of CPUCres: 2 (1 Socket (s),2Core (s) per Socket) -the successful launch

The number of active VMs is bigger than the physical cores in the host.
This is not an accurate statement. You could run, for example, 5 single vCPU VMs on a 4 core hypervisor. Y.
