Hello all,
I recently got admin rights to a small vSphere 5 environment (2 physical hosts, ~25 VMs).
The people who set it up didn't have the correct knowledge about CPU core scheduling on the physical hosts resulting in most VMs having 2 or 4 vCPU, even tho they're barely using any CPU power at all.
The VMs are either running Windows 2008R2 or Ubuntu 12.04 LTS. Does anyone knows what the impact on the VMs would be if I reduce the amount of vCPU to 1? (Besides the VMs being less powerfull ofcourse).
