+Running Tails in Qubes
+============================
+
+Tails is the amnesic incognito live system. It aims are preserving privacy and anonymity.
+
+To run Tails under Qubes:
+
+1.  Read about [creating and using HVM qubes](https://www.qubes-os.org/doc/hvm/)
+
+2.  Download and verify Tails from http://tails.boum.org in a qube, (saved as "/home/user/Downloads/tails.iso" on qube "isoVM" for purposes of this guide).
+3.  Create a HVM
+
+  - in Manager, click VM menu and select "Create VM"
+  - Name the new qube - "Tails"
+  - Select "HVM"
+  - Configure networking
+  - Click "OK" to create new HVM.
+
+4.  Open dom0 Konsole and start Tails:
+
+        qvm-start Tails --cdrom=isoVM:/home/user/Downloads/tails.iso
+
+5.  Configure Tails at start up.
+
+6.  Once the Tails qube has started, configure networking in the qube.
+
+  -  Check the IP address allocated to the qube - either from GUI Manager, or ```qvm-ls -n Tails``` in Konsole. (E.g. 10.137.1.101 with gateway 10.137.1.1)
+  -  In the Tails qube, open systems menu in top-right corner. Select "Wired Settings", and change  IPv4 configuration from "Automatic (DHCP)" to "Manual".
+  -  Enter the Address:   10.137.1.101  in our example.
+  -  Enter the Netmask:   255.255.255.0  
+  -  Enter the Gateway:   10.137.1.1  in our example.
+  -  Enter DNS:           10.137.1.1  in our example.
+  -  Click "Apply". You should now see "Connected".
+
+7.  Use Tails as normal.
+
+## Usage Notes
+
+###Display issues:
+**Black screen on start up.**
+
+This was reported with earlier versions of Tails: I believe the problem is now fixed.
+If you do encounter this problem, you can try to constrain display settings by appending vga codes to the Tails boot parameters.
+(If you do not know the codes, append vga=999, and a helpful prompt will appear.)
+
+N.B Tails 2.3 does not appear to honour the vga code.
+
+**Window extends beyond bottom of screen.**
+
+This seems to arise because Tails sizes to the height of the screen, but there is a title bar at the top of the window.
+Either remove the title bar altogether, or move the window upwards using ALT+drag.
+
+###Persistent Volume
+The persistence tools will not work because Tails has not been launched from USB.
+The HVM disk(s) can be configured and mounted from within Tails to provide persistent storage. 
+
+###Shutdown
+The Tails qube will not shut down cleanly.
+Kill it from the GUI Manager or ```qvm-kill Tails``` in Konsole.
+
+###Security
+You will probably want to implement [MAC spoofing](https://www.qubes-os.org/doc/anonymizing-your-mac-address/).
+
+Read [the warnings](https://tails.boum.org/doc/advanced_topics/virtualization/) from the Tails team about operating in a virtual machine.
+While the Qubes security model mitigates most of the risks identified, traces of the Tails session may remain on the disk.
