Yes, snapshot the disk of running VM by 'qemu-img snapshot' or 'collie vdi snapshot'
QEMU has 3 kinds of snapshot,
     - live disk and memory snapshot of running VM by 'qemu monitor vmsave',
       similar to laptop suspend
     - snapshot of disk when VM is powered off by qemu-img or 'collie vdi snapshot'
     - snapshot of disk of running VM <--- I meant this.
