From: lei yao <lei.a.yao at intel.com>
1. Server mode In vhost reconnection test, we need set qemu
work in server mode(default is client mode) The sample command is :
"-chardev socket,id=char0,path=./vhost-net1,server"
2. Multiqueue
We can set multiqueue connection between vhost and virtio. Add this parameter for the
multi-queue performance testing. The sample command is: "-netdev
type=vhost-user,id=mynet1,chardev=char0,vhostforce,queues=4"
3. Change the VM launch waiting time.Some times,we find that lauching vm need more time.
So change count=20 to count 40
