VMWare, Number of processors
I have a machine with 2 sockets and 6 cores per socket
The cores are Hyperthreading enabled according to the VMWare Host
I have 2 Windows VM's. I set them both to 1 soecket and 6 cores to fully utilize the 12 physical cores.
However, when I bring up the VM and look in the Task Mgr, and hit the Performance tab, I see 6 cores.
I expected to see 12 cores because I allocated 6 physcial cores, and each core has 2 threads, so the Task Mgr should show me 12 cores
Am I missing something
How should I diagnose

I get very confused on this subject
I have 2 sockets at 6 cores per socket, HT enabled
So when I allocate a VM CPU in Edit Settings, if I allocate the following
Did I allocate 6 virtual cores, or 6 physical cores ?

Sockets: 1
Processors: 6Did I allocate 6 virtual cores, or 6 physical cores ?
the options are Sockets and Cores. (not processors).
1 Socket and 6 Cores is 6 vCPU in the VM.
Virtual Machines use virtual processors (vCPUs).
1 vCPUs = 1 Physical Core on the host (simplified). This is scheduled across all the Cores in the Physical Host, so this may not be the same core, all of the time.

If you want 12 vCPUs in the VM,
allocate 12 Sockets, 1 Core
or 2 Sockets, 6 Cores!
it still equals 12 vCPUs in the VM!
(it's the same it does not make any performance difference, it's just for licensing, if you have OS or Applications that are Licensed per Core)

Yes, I understand that I have
and I also understand that therefore I have
However, what I am having difficulty understanding is when I go to the
and see the following:
With this definition, am I using 6 Logical Processors or 12 Logical Processors
2 Sockets
6 cores per socketand I also understand that therefore I have
24 Logical ProcessorsHowever, what I am having difficulty understanding is when I go to the
VM->EditSettings->CPUand see the following:
Number of Virtual Sockets: 1
Number of cores per socket: 6
Total number of cores: 6With this definition, am I using 6 Logical Processors or 12 Logical Processors
