Define vCPU Define vCPU disturbedone (Vendor) (OP) 26 Apr 12 02:34 Is one vCPU equal to one core?We have Intel Xeon X5450 quad-core processors in our hosts. A VM has 1vCPU. Does that mean is essentially has a single single-core processor? Or does it mean it has a single quad-processor?

Is there any difference if I assign a 2nd vCPU vs assigning a 2nd vCore?
