Hi,
I need some advice on the maximum number of CPU cores that we can assigned to each VM as well as the maximum number of physical CPU cores on the host machine.
I have came across some specifications mentioning about virtual CPUs and virtual cores. Are they refering to the same thing?
1 virtual core is equivalent to how many physical core? 1 virtual CPU is equivalent to how many physical CPU or core?
Appreciate your kind response on the above. Thanks.
Regards

On ESX 1 vCPU is a logic core.
It is a core in a CPU socket, but could also be logical core of one core (if you have HT enable).
On ESX/ESXi 3.5 there is a limit of max 4 vCPU for each VM.
On ESX/ESXi 4.0 there is a limit of max 8 vCPU for each VM, but you will need virtual hardware 7 and a Enterprise Plus license
