I would like to ask for my own clarification regarding the vCPU to core aspect. Is core in this case referring to logical cores (logical processor) or physical core? I ask due to the below section taken from the "Virtual CPU Limitations" section of the vSphere Documentation Center. The reference to the hyperthreaded proc being called a "logical core" is what I am referring too. What I am trying to determine is the very thing that the TheVMinator has asked.
"A virtual machine cannot have more virtual CPUs than the
number of logical cores on the host. The number of logical cores is equal to the
number of physical cores if hyperthreading is disabled or two times that number
if hyperthreading is enabled."
Thank you much for any information.
