such as KVM_FEATURE_IPI and KVM_FEATURE_STEAL_TIME, however paravirt
feature KVM_FEATURE_VIRT_EXTIOI is controlled from qemu VMM rather KVM
host.

From qemu VMM side, all paravirt features should be controlled. Here
property of paravirt features are added, also feature dection and
enabling is added here.
