Build openvswitch into the image and configure the system with the following steps. Note that the built-in mirroring related self test cases are all passed.
1. prepare guest image
copy guest kernel and image(qemux86 image) under /exports/guest1 , as below
root@intel-x86-64:/exports/guest1# ls -l
total 7095864
-rw-r--r-- 1 root root 9142176 Jan 16 19:37 kernel
