Hi guys,
When I have, for example, a processor with 2 CPU x 1,866 GHz and I create a VM with 1 vCPU, its virtual clock is configured with 1,866 GHz, however when I create a VM with 2 vCPU, instead of ESXi calculate the VM virtual clock to 2x1866=3722, this VM is configured with 2512 MHz. Please see the following images:
I've made another test. I have another server with 8 CPU x 2,127 GHz. This value in our virtual machines is shown correct with 2, 3 or 4 vCPUs, but it's not with 8. There is a VM there with 4 vCPU and its virtual clock is shown with 2127x4=8508 MHz, I mean, the "logic" is correct. Meantime, when a VM uses 8 vCPUs, matching the physical host, ESXi always takes out an amount of clock. I've created a VM with 4 sockets and 2 cores, its clock virtual is shown with 14782 MHz, but I think that ESXi should show 8x2127=17016 MHz.
