  • Thread-topic: xen scheduler question

If there are two guest running one with 1 VCPU and other with 2 VCPU with equal weight and no cap on a dual core machine, how will Xen assign the physical CPUs to guests? Does Xen treats weight on domain basis? If that’s true then VCPU of domain with one VCPU will be scheduled twice as often then the VCPU of other domain. Right?
