@Li Chengyuan, is your host OS really 12.04 (aka Precise)? Because in 12.04 the qemu version is 1.0 and the fix would not apply. I am not sure that old qemu is even affected since the code is very different. Backports of the fix seem only to make sense up (or back) to 14.04 (aka Trusty) which would also match the qemu version 2.0 which you mentioned.
