+====

+Some functionnalities works differently if you use 'qemu' as technology. In order to create a new VM with qemu, you need to specificy some more informations.
+You can also clone a qemu template which already is on your Proxmox server.
+
+QEMU profile file (for a new VM):
+
+.. code-bock:: yaml
+  proxmox-win7:
+    # Image of the new VM
+    image: image.iso # You can get all your available images using 'salt-cloud --list-images provider_name' (Ex: 'salt-cloud --list-images my-proxmox-config')
+
+    # Technology used to create the VM ('qemu' or 'openvz')
+    technology: qemu
+ 
+    # Proxmox node name
+    host: node_name

+
+More informations can be found on Proxmox API under the 'POST' method of /nodes/{node}/qemu/{vmid}/clone
+
+.. note::
+    The Proxmox API offers a lot more options and parameters, which are not yet supported by this salt-cloud 'overlay'. Feel free to add your contribution by forking the github repository and modifying  the following file : salt/salt/cloud/clouds/proxmox.py
+    An easy way to support more parameters for VM creation would be to add the names of the optionals parameters in the 'create_nodes(vm_)' function, under the 'qemu' technology. But it requires you to dig into the code ...
