ok thanks , but then can we know which all list of feature are supported by QEMU/KVM release. http://www.linux-kvm.org/page/KVM_Features

This page is not really about CPU features. It's not so easy to tell whether a given CPU feature will be available to a guest or not as it depends on a lot of things: QEMU and KVM version, machine type, hardware settings, and even a specific revision of a given CPU model installed in your host. Probably the simplest way to see the features is to check them in a guest OS. If everything goes well you should be able to get similar info from libvirt via "virsh domcapabilities" command soon. Hopefully with QEMU 2.9.0 and libvirt 3.1.0. Jirka
