[Qemu-discuss] live migration on shared storage

is there any documentation about vm live migration with qemu monitor commands
when running the VM's on shared storage?

My vm's are running with virtual discs based on rados block devices based on 
ceph storage
cluster started with:

/usr/bin/qemu-system-x86_64 -daemonize -pidfile /etc/conf.d/kvm/awv29/pid \
  -monitor unix:/tmp/awv29.monitor,server,nowait -name kvm -boot c \
  -m 8192 -vnc al54:34 -net nic,macaddr=52:54:00:8:31:22,model=virtio \
  -net tap,ifname=tap34,script=no,downscript=no -k de -rtc 
base=localtime,clock=host \
  -usbdevice tablet -smp 2 -enable-kvm

The documentation at http://www.linux-kvm.org/page/Migration includes the 
transfer of
the virtual disc images between the virtualization hosts. That makes no sense 
for me

My qemu vesrion is 2.4.0.

Thanks in advance.
