Performance of Xen VCPU Scheduling - XenIntroduction This page evaluates the performance of the Xen VCPU schedulers with different parameters/patches and under different guest loads. The motivation was the observation that a configuration where dom0 vcpus were pinned to a set of pcpus in the host using dom0_vcpus_pin and the guests were prevented from running on the dom0 pcpus (here called "exclusively-pinned dom0 vcpus", or xpin) cause
