+2. Run some memory work loads on Guest, for example, ./memtester 1G 1
+3. Set migration parameters in QEMU monitor. On source and destination, 
+   execute: #migrate_set_capability compress on
+   Other compression parameters are all default. 
+4. Run migrate command, # migrate -d tcp:10.156.208.154:4000
+5. The results: 
+   - without compression：  total time:  197366 ms   throughput:   937.81 mbps  transferred Ram: 22593703 kbytes 
+   - with compression: total time:  281711 ms   throughput:  90.24 mbps    transferred Ram: 3102898 kbytes  
+
+When compression is enabled, the compression transferred ram is reduced a lot. But the throughput is down badly.
+The total time of live migration with compression is longer than without compression. 
+I tried with 100G network bandwidth, it also has the same problem."""
