unable to get more than 4 vCPU

vmgeekko Oct 13, 2019 9:27 PM

I have server with 2x E5-2670 CPU that's total 16 cores, 32 thread, I have hyperthreading enabled but I am only see 4 VPU. Following is what i see on vmware for the host:

Logical processors: 4

processor type: intel(R) CPU E5-2670 0 @ 2.6 GHz

Sockets: 2

Cores per socket: 1

Hyperthreading: yes, enabled

how to oncrease vCPU? I want to assign 20 vCPU to my vm. I have enterprise plus permanent license. I am running ESXi 6.7

This seems to be License issue for me. vSphere licenses are per CPU basis and this could be the reason that you are only able to see 4 CPU in host.

Please read below article and check your license,

This Intel CPU have 8C/16T each. If ESXi only recognice 1C/2T each than something goes wrong at the very first

Please can you check the BIOS of your Server if all Cores are enabled? As a long time Dell user i know that you can reduce the number of Cores within the BIOS for "licensing" reasons to please check the BIOS first.

What ever your ESXi version is you should see 2x 8C/16T = 32 logical CPUs in the summary. Yes, also with the free ESXi Hypervisor you should see this.

Go to the License tab and check how many CPU's it shows there.

I have already written above.

About licensing. I deal with VMware lics for more than 11 years and i cant remember if there ever was a lic/method around which makes happen what you currently see.

Does the Hypervisor see the correct amount of CPUs?
