[CentOS-virt] Differences between qemu-kvm and qemu-kvm-ev

[C. L. Martinez]

Hi all,

 What are the real technical difference between qemu-kvm and
qemu-kvm-ev packages? What are the advantages to use qemu-kvm-ev (if
exists someone)?

 Or qemu-kvm-ev makes sense when is used with ovirt only??

Thanks.
