The linux kernel recently added support for paravirtual spinlock handling to avoid performance regressions on overcomitted hosts. This feature needs to be turned in the hypervisor so that the guest OS is notified about the possible support. This patch adds a new feature "paravirt-spinlock" to the XML and supporting code to enable the "kvm_pv_unhalt" pseudo CPU feature in qemu. https://bugzilla.redhat.com/show_bug.cgi?id=1008989
