+Create New Disk
+===============
+
+
+Import Existing Disks
+*********************
+
+Now that we have our cluster working, we probably wish to see something running
+on it.
+Instead of creating a new vm from scratch, we import an existing disk:
+
+::
+
+    # qemu-img convert -f qcow2 wheezy.qcow2 sheepdog:wheezy
+
+Now we have a vdi disk.
+
+::
+
+    # collie vdi list
+    Name        Id    Size    Used  Shared    Creation time   VDI id  Copies  Tag
+    wheezy      1   10 GB  1.7 GB  0.0 MB 2013-02-11 12:31   a34c67     3
+
+We are ready to run the vm on any of the node.
+
+::
+
+    kvm -drive file=sheepdog:wheezy -m 512 -smp 2 -vnc :1 -daemonize 
+
+**IMPORTANT:**
+Do NOT use the same vdi twice!
+This may simply happen if you run the same guest on two different hosts.
+The vdi will be corrupted.
+Vice versa, if you run the same guest (or another using the same vdi) on the
+same host, you'll get an error about disk already in use (no corruption).
+
+
+New Vdi
+*******
+
+If you wish to install a new operation system you need an empty vdi and an iso
+file.
+
+::
+
+  # collie vdi create windows7 30G
+
+  kvm -drive file=sheepdog:windows7 -cdrom /tmp/windows7.iso -m 2048 -smp 2 -vnc :2 -boot order=d -daemonize
+
+Note: you may import the iso as well
+
+::
+
+    # qemu-img convert /tmp/windows7.iso sheepdog:windows7.iso
+  
+and then
+
+::
+
+    kvm -drive file=sheepdog:windows7 -cdrom file=sheepdog:windows7.iso -m 2048 -smp 2 -vnc :2 -boot order=d -daemonize
