It seems that the sheep daemon segfaults when you stop the VM without
shutdown.  I think this is a bug.  Sorry for the inconvenience.

Normally I just enter this command in terminal "qemu-system-x86_64 sheepdog:box02a" and when I close terminal or session it closes and also VM shuts down. I want to keep VM in running  state and get access to it in its current status. How to do it ?

One simple way is using GNU screen.
