raw vs qcow2
Raw file format provides slightly better performance while qcow2 offers advanced features such as copy on write and Live_Snapshots. Since V2.3, qcow2 is the default format.
Make it really easy:Build your ISO with drivers already included: Windows guests - build ISOs including VirtIO drivers
