[Qemu-devel] [PATCH COLO-Frame v19 19/22] COLO: Update the global runstate after going into colo state

[zhanghailiang]

If we start qemu with -S, the runstate will change from 'prelaunch' to 'running'
after going into colo state.
So it is necessary to update the global runstate after going into colo state.
