-====== Nova RDP Support======
+====== Nova RDP Support Configuration======
 Nova currently provides support for [[http://en.wikipedia.org/wiki/Virtual_Network_Computing|VNC]] and [[http://en.wikipedia.org/wiki/SPICE_(protocol)|SPICE]] graphical consoles. VNC in particular is the protocol employed natively by most popular hypervisors supported by Nova. [[http://en.wikipedia.org/wiki/Hyper-V|Microsoft Hyper-V]] in this context is a remarkable exception, as it employs the [[http://en.wikipedia.org/wiki/Remote_Desktop_Protocol|Remote Desktop Protocol (RDP)]] for graphical console access, based on [[http://msdn.microsoft.com/en-us/library/jj712081.aspx|Open Specifications]] and implemented by various open source projects.
-===== Getting an RDP console URL =====
+[[http://www.youtube.com/watch?v=DhBa-IuTQAs|Here]]'s an example video showing an HTML5 RDP console based on [[https://github.com/FreeRDP/FreeRDP|FreeRDP]].
-This requires a public API which is symmetric with the VNC and SPICE ones.

+===== Configuring Nova for RDP support =====
-^Verb	^URI			^Description					^
+RDP console configuration is quite straightforward. All you need to do is to add the following configuration settings in your Hyper-V compute node's **nova.conf**:
-|GET	|/servers/{id}/action	|Gets the URL for accessing the RDP console.	|
-==== Example. Get RDP console URL request: XML ====
+    [rdp]
+    enabled=True
+    html5_proxy_base_url=http://10.0.0.1:8000/
+Where the url specified in the **html5_proxy_base_url** setting is provided by the FreeRDP HTML5 proxy as detailed in the next section.
-<code xml>
+===== Installing and configuring the FreeRDP HTML5 proxy =====
-<?xml version="1.0" encoding="UTF-8"?>
-<os-getRDPConsole type="rdp-html5" />
-</code>
-==== Example. Get RDP console URL request: JSON ====
+The FreeRDP HTML5 proxy can be installed on various Linux distributions (currently Ubuntu >= 12.04, RHEL 6.x / CentOS 6.x and Fedora >= 16) or on Microsoft Windows, including Hyper-V Server.
-<code javascript>
+==== Ubuntu 12.04 and above ====
-{
-    "os-getRDPConsole": {
-        "type": "rdp-html5"
-    }
-}
-</code>
-==== Example. Get RDP console URL response: XML ====
+A shell script is provided to simplify the installation of the application and the dependencies, mostly available in source form only.
-<code xml>
+    sudo apt-get install -y git
-<?xml version='1.0' encoding='UTF-8'?>
+    git clone https://github.com/FreeRDP/FreeRDP-WebConnect.git
-    <console>
+    cd FreeRDP-WebConnect
-        <type>rdp-html5</type>
+    sudo ./setup_all.sh -f -i
-        <url>http://example.com:6083/?token=f9906a48-b71e-4f18-baca-c987da3ebdb3</url>
-    </console>
+At this point the proxy, called **wsgate** can be installed by running:
-</code>
-==== Example. Get RDP console URL response: JSON ====
+    sudo make install
-<code javascript>
+==== wsgate configuration ====
-{
-    "console": {
-        "type": "rdp-html5",
-        "url": "http://example.com:6083/?token=f9906a48-b71e-4f18-baca-c987da3ebdb3&title=dafa(75ecef58-3b8e-4659-ab3b-5501454188e9)"
-    }
-}
-</code>
+The default configuration file is located here:
-===== Getting console connection details =====
+    /usr/local/etc/wsgate.ini
+Change the following options to match your environment configuration:
-Nova includes internally the required proxy solutions for VNC (novnc, xvpvnc) and SPICE, but this is not the case for RDP. Beside that, it's also desirable to leave to third party the ability to choose a custom graphical console UI solution not necessarily included with Nova. A public API has been provided to retrieve the relevant information by providing a valid console authentication token.
+    [global]
+    port = 8000
-==== Get console connection info: V2 API ====
+Note: make sure to open the port in your operating system firewall.
-^Verb	^URI			^Description									^
+    [openstack]
-|GET	|/console-auth-tokens/{token_id}/action	|Gets the connection info for the specified console authentication token.	|
+    authurl = http://10.0.0.1:5000/v2.0
+    username = admin
+    password = secret
+    tenantname = admin
-Normal Response Code(s): 200
+    [hyperv]
+    # Credentials used to connect to the Hyper-V hosts when accessing
+    # OpenStack instances consoles
-Error Response Code(s): badRequest (400), unauthorized (401), itemNotFound (404)
+    hostusername = Administrator
+    hostpassword = secret
+It is also strongly recommended to encrypt the traffic using HTTPS. Here are the relevant parameters, including a PEM file containing both the certificate and the private key.
-==== Example. Get console connection request: XML ====
+    [ssl]
+    port = 4430
+    certfile = /usr/local/etc/wsgate/test.pem
+    certpass = verysecret
-<code xml>
+HTML, CSS and Javascript files are available at the following location for further customization:
-<?xml version="1.0" encoding="UTF-8"?>
-<os-getConsoleConnectInfo/>
-</code>
-==== Example. Get console connection request: JSON ====
+    /usr/local/share/wsgate
-<code javascript>
+==== Running wsgate ====
-{
-    "os-getConsoleConnectInfo": null
+wsgate can be executed as a demon with the following instruction:
-}
-</code>
-==== Example. Get console connection response: XML ====
+    wsgate -c /usr/local/etc/wsgate.ini
-<code xml>
+In case you should prefer to execute wsgate in a shell for debugging purposes, just set:
-<?xml version='1.0' encoding='UTF-8'?>
-<console>
-    <instance_uuid>b48316c5-71e8-45e4-9884-6c78055b9b13</instance_uuid>

-    <internal_access_path>51af38c3-555e-4884-a314-6c8cdde37444</internal_access_path>
-</console>
