qemu-kvm and qemu-kvm-ev are usually built from the same src.rpm.
Some newer or advanced virtualization features have been implemented in
qemu-kvm-ev which are not able to be backported to qemu-kvm for
compatibility reasons.
Also, recently qemu-kvm-ev has a newer qemu-kvm version than the one
provided by qemu-kvm being qemu-kvm-ev rebuilt from Red Hat Enterprise
Virtualization.

Sandro,

Could you please enumerate the actual technical differences between stock 
qemu-kvm and qemu-kvm-ev?
For example, what could one do with qemu-kvm-ev that cannot with qemu-kvm?
