Fix NOT included in qemu-kvm-0.12.1.2-2.415.el6_5.13 due to broken build.
Clearing "Fixed in Version" field and changing BZ status to POST.

Comment 26 Fam Zheng 2014-08-14 05:40:15 EDT 
Yes. ioeventfd should have more effects on high speed IO. The BW/CPU degradation has a separate bug (1121034) so I think this bug can be verified.

Thanks,
Fam
