Hi I just wondering if someone have tried the driver that red hat realest for windows. http://www.linux-kvm.com/content/red...-block-drivers
My goal is to move most of the virtual machines to kvm with virtio enabled.

Notice the changes on the write speed with the image format raw.
From 15 mb/s to 34.5 mb/s.

Just wondering if someone have a solution to increase the write speed to disk on qcow2
