If one was to run "A VM with Win2K8 Enterprise, 64bit - needs 8 vCPUS" - in a real world environement, but the only options in the VM edit settings page we ONE, TWO or FOUR vCPUs then would the reason for this potentially be?....
An ESX 3.x host has two AMD dual-core CPUs - OR - An ESXi host has two Intel dual-core CPUs.
Is there difference between the ways which AMD/ESX present vCPUs in comparison to Intel/ESXi??? As far as I was concerned, both options would only allow you configure a VM (irresepctive of OS) with a MAXIMUM of 4 cores (two from each Socket?)
Can anyone push me in the right direction as I am entirely confused about this...?

No there is no difference between AMD and Intel - the issue is the ESX 3.x only support 4 vcpus -
intel has HT technology and AMD doesn't
so with a 2 x dual core intel cpus you could make a 8 vCPU virtual because is has 4 physcial cores but 8 logical, where 2 x AMD dual core cpus can only make a 4 vCPU virtual.
Cheers
and ESX 3.x does not support 8 vCPUs -
Thanks - this totally makes sense REGARDLESS which version ESX, or even which version of another OS you are using!
