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. > QEMU does not have a built-in way to migrate the original qcow2 file itself. Are there any good ideas to fork a running VM with previous snapshot image? ------ suzaki
