    Yes, that's the normal mode of operation. The hypervisor will timeslice
    multiple vcpus onto a single vcpu.

    This patch doesn't relate to that; it's whether a Xen Linux guest's
    kernel can be preempted to reschedule processes while running under Xen.
    The normal xen-unstable or vendor Xen kernels don't support this, but
    the mainline kernel with paravirt_ops/xen support does.
