What was the commit hash for the QEMU you tested?
The following caused a major regression in qcow2:
commit a16c53b101a9897b0b2be96a1bb3bde7c04380f2 Author: Anthony Liguori <aliguori@us.ibm.com> Date: Mon Jun 6 08:25:06 2011 -0500
Fix regression introduced by -machine accel=
Commit 85097db6 changed the timing when kvm_allowed is set until after kvm is initialized. During initialization, the ioeventfd initialization cod checks kvm_enabled() and after this change, ioeventfd is effectively disable
If it's not in your tree, it would be useful to rerun the test with the latest git.
