> 
> From: lei yao <lei.a.yao at intel.com>
> 
> The test case include 2 part:
> 1. virtio 0.95 performance test
> virtio0.95 is the default version for qemu. Vector, normal, mergeable path
> will be tested on this version
> 2. Test vector performance on virtio 1.0.
> 
> Change in V4
> The cmd is changed to based on self.target
