Vmware dynamic or fixed CPU

I am running vmware 4.1. How can I tell if the VCPU's are dynamic or fixed. I always presumed they were fixed and you could not have dynamic?

What do you mean dynamic vCPUs? Are you talking about being able to add CPU hot? If this is what you mean see this link

For ESXi host, By default vCPU is set as dynamic. To fix the CPU limit for any VM machine you need to set the reservation for VM machine. Post setting reservation, Particular amount of vCPU is always reserved for VM machine even though it is not in used.

Below is the stesp to reserved the vcpu for VM machine :-

1. Power off the virtual machine.
2. Right-click on the virtual machine and click Edit Settings.
3. Click the Resources tab.
4. Set the CPU limit as required.

You can make them static, by fixing a VM to a specific core, changing affinity, but why would you want to do this, when we pay lots of money to VMware and let the Hypervisor do the donkey work, of moving the VM from Core to Core for us?

Edit the CPU Options in the VM, change the Affinity to a specific core.
