Windows 7 on a Raspberry Pi (sort of)

15th of May 2012 by liz

Microsoft Windows, you say? Love it or hate it, some of you are stuck with having to use it, thanks to decisions made higher up the tree at work. As you probably know, the Raspberry Pi can’t run Windows – but the guys at Citrix have come up with a third way.

This video shows Citrix’s XenDesktop remote desktop running a Windows 7 virtual desktop session. Run a bunch of instances of Windows on your server, push the displays out to many Raspberry Pis, and you’ve got a cheap way of getting Windows onto desks at work, without having to fork out for a full-cost PC. We’re beginning to understand that there are ways to lower the cost of ownership using a Raspberry Pi even for businesses which aren’t prepared to switch over entirely to open-source software – neat, isn’t it?

Errrr, this is news how?

With software like tightvnc & rdesktop (MS Windows) this is hardly a big deal.

The only difference with XendDesktop is the remote desktop is a “cloudy” saas.

  It’s kind of important to realise, John, that there are people out there who aren’t familiar with VNCs, and who aren’t aware that this sort of option’s open to them – those are, largely, the sort of people we hope will be buying Raspberry Pis. For people who aren’t lucky enough to be like you, it’s news.

      Citrix was *THE* software to run virtual desktops all through the 90s. Citrix came before Microsoft’s remote desktop (in fact, Windows’ Terminal Server was based on a Citrix product). Citrix are still very import in the world of enterprise virtual desktops, which is why this news story makes sense.
      
      How, do you suppose, would you create and manage 200 remote desktops from one server using VNC? That was rhetoric, of course because you wouldn’t, you’d use Citrix.

  This could have advantages over VNC and other remote desktop solutions, like acceleration and acting like a full Windows terminal. Citrix for Playbook for example is awesome compared to other remote desktop solutions.

  That wouldn’t work even if you could process in parallel. The biggest issue is that Windows is compiled for an x86 processor, and the R-Pi has an ARM processor. The only way to run windows is to do a very slow sort of emulation by translating each individual opcode from one set to the other. Doing this on the fly is called “Interpretation” and another technique that works well is called JIT, which is short for Just-In-Time compiling. They’re both very complicated and not nearly fast enough to run windows.
  
  The other main issue is the lack of RAM; while the cluster would solve this issue partly, any newer version of windows consumes nearly a Gig (!) of RAM just by itself, and you’d be swapping pages across the network constantly to do anything. You might be able to get some performance out of Win 98 or Win XP (which are much lighter on memory consumption) but it’s still going to be very slow.
  
  If you’re bent on trying, what you want is something more like Qemu, which can do the kind of emulation needed to simulate x86 on another platform.

As soon as I heard about the Raspberry Pi I thought it would find a good purpose as a thin client. Apart from possible use in business, schools could roll out Raspberry Pies to all the desktops and use them to access Windows servers or Edubuntu via LTSP as well as teach programming with them. I’m going to have a Pi that will be used to access my PC in another part of my house.

  My thoughts exactly. Once video drivers come along and the issues with SD cards settle down this could be a very cheap application for businesses that already use thin clients, they could make their own locked down images simply to allow launching of virtualised desktops as seen in the video above. A ModMyPi case has VESA mount holes ready to go so that the Pi’s could be mounted to the back of monitors all neat and tidy while using very little power and space. Interesting for sure.

  Well, actually it’s RPi + power adaptor + monitor + case + SD card + setup time + all the usual overheads (cables, etc.). Which could easily bring it into the £100+ category before you even start if you’re intending to sell them to businesses, or even if you do all the work and support yourself (business time != free).
  And then, let’s be honest, all you’ll be running is Linux “fat”-clients, not thin-clients and you’d spend you’re life updating the software, diagnosing software faults, fsck’ing the SD card, etc.
  For business use, a purpose-built thin-client would be cheaper, easier, less support hassle, more integrated and more standardised, and not one bit more expensive than using a RPi setup made to the same standard.
  Sure you could Heath-Robinson something up quite cheaply but the expensive bits aren’t the “motherboard” (if you like) but the casings, standard attachments and most importantly time (support time, maintenance time, installation time, etc.)

    nonsens, most thin client you buy are based on linux.
    The best thing is that you can take a thinclient distro like ThinStation and you can tinker it to you linkings and make it perform as you wish.
    The RPi is static, if it breaks replace it or replace the SD card.

    Really? Every time I’ve (casually) looked at thin-clients, I’ve always been shocked at how expensive they are! Don’t they also need power adaptors, monitors and cables?
    I’d love to see a concrete example of a commercial thin-client that’s cheaper than a RPi.

      I can back this up. A thin client can cost up to 200-300 euros and you still need to purchase individual licenses (which you must buy from the thinclient provider, otherwise you’re not getting the client). It’s a silly construction but keep in mind a thin client uses MUCH less power, much less ICT personnel; in 5 or 6 years it’ll be a fraction of the cost of a fat client (which can cost thousands for a company including maintenance, personnel, etcetera

XenDesktop is a great corporate solution for Windows, though obviously comes at a price (and the price for the client software is high as well as you need terminal services licenses). I’m going to (when I get around to it) investigate / benchmark NXClient on the Pi – as this is a great open source alternative, especially when combined with something like OpenOffice or even Crossover Wine running Office (with the appropriate licenses of course!) – that has potential in the education environment.

  The problem with Windows 8 is that it will only allow one instance at a time. So if you are logging in you main computer, and do remote desktop with the raspberry pi, it will log you out.

I mentioned on the forums a while back that one of the first things I was going to do when I finally get my RPi is to set it up to boot a saved EC2 instance on startup and then RDP to it. That way you could have an entire office running windows with an active directory (virtual) server but each “PC” only costs $25 (excluding screen etc) plus $0.02 / running hour for admin machines or $0.12 / running hour for developer machines. Even cheaper with reserved instances, plus you can back up entire computers automatically.

To those people that are commenting that this is not new, well it’s is true, thin clients are not new but that does not mean that they should not mention it. There are a lot of people out there who are not familiar with the concepts and some technologies like pcoip and rdp that provide a really good support for remote desktops.

I am really excited and I am awaiting for my rpi really badly. At my university I worked in a project that developed a client and server platform for deploying low-cost thin client(I mean really low cost, no HDD, 256mb of ram, pentium d/4) and I would really love to get my rpi to keep working in this project see what else I could come up.

Thanks Liz and the entire RPI Foundation for the great work!

Of course you would need to pay for for the Windows 7 licenses on the server and presumably also for the XenDesktop licenses…But this would be ideal for something the LTSP (http://www.ltsp.org/), requiring little storage on the pi at all to distribute an environment all around the office/house/classroom. Does the pi have PXE network boot? if it doe,s an SD-less boot beckons.

  An SD-card is needed in any case, because its the only medium the R-PI will boot from, after that the boot can continued via another medium, but initial boot is always from the SD-card.

A big problem with remote desktops is that they are very bad in fast changing things on the screen, like movies and animations. If you want to do that right, it will need massive amounts of processing power, all decoding must be done in software on the server, and network bandwidth. Much educational software is based around movies and animations. That makes remote desktops less usable for schools.

Remmina works fine on the Pi.

Simply:

I use it all the time from Linux Mint and it seems to work similarly well on the Pi.
