Excuse me. My explanation was not enough.
I want to fork a running VM to another machine. I hope that each VM
has same QCOW2 file on each machine. Therefore I tried to use Block
Migration but it did not bring snapshot images.

Are there any good ideas to fork a running VM with previous snapshot image?
