2, start a KVM virtual machine with Virt-image
~]#virt-install--name=testnode1--ram 3072--vcpus=2--disk Path=/root/kvm/testnode1.qcow2,device=disk, format=qcow2,bus=virtio,cache=none,size=30--os-type=linux--graphics vnc,listen=0.0.0.0,port=5931,--network Bridge=br0--network bridge=br1--force--cdrom/iso/ubuntu-14.04.1-server-amd64.iso--autostart
