Hello All,
I have a silly question. I am trying to calculate a 1:1 vCPU:pCPU ratio, so no CPU oversubscription. The system has Hyperthreading enabled.
If I have a physical host with 48 physical cores and Hyperthreading is enabled, in order to use all the physical cores (but not oversubscribe), would I size the VM with 48 vCPU or 96 vCPU?
To use all 48 physical cores, I am thinking I should configure the VM with 96 vCPU. If the VM is sized with 48 vCPU, I'm only using half of the physical cores I paid for.
Please let me know. Thanks.
