[ovirt-users] Doubts about performance qcow2 and raw in newer versions of KVM

[Tácio Andrade]

Staff would like to know if anyone here in the group has done a comparison
between RAW and qcow2 discs to see if the performance loss is even as large
as speak. I ask this because I saw on the KVM project site a comparative
table, however is based on a version of qemu 2009 apparently, so I wonder
if it is still valid or hear improvements in qcow2.

Another doubt that I have with respect to this article, which he said is
the IDE driver has outperformed virtio, the new version is so? I question
this because I always read the virtio driver is the most suitable for an
installation using KVM.

Thank you in advance for help.
