Some more details about this experiment:
The host is running Ubuntu-16.04 with 4.4.0 Linux kernel and QEMU-2.5.1; The
guest is running Ubuntu-12.04, except Memcached with Ubuntu-16.04.
The exact numbers of the proportions of write-not-dirty pages for the first
2 pre-copy iterations: (0.445 means 44.5%)
Memcached: 0.445, 0.478
Zeusmp: 0.670, 0.727
Mcf: 0.808, 0.793
Bzip2: 0.464, 0.447
Milc: 0.341, 0.037
cactusADM: 0.280, 0.248
lbm: 0.090, 0.037
GemsFDTD: 0.226, 0.172
Bwaves: 0.069, 0.003
Astar: 0.113, 0.039
Xalancbmk: 0.082, 0.041
