+	  Paravirtualized scheduling facilitates the exchange of scheduling
+	  related information between the host and guest through shared memory,
+	  enhancing the efficiency of vCPU thread scheduling by the hypervisor.
+	  An illustrative use case involves dynamically boosting the priority of
+	  a vCPU thread when the guest is executing a latency-sensitive workload
+	  on that specific vCPU.
+	  This config enables paravirt scheduling in the kvm hypervisor.
