Xen Project Q&A Forum: First Line Help for Simple Questions
This is your chance to ask questions and provide answers about basic use of the Xen Project software.

Does Xen host virtual windows 7/8 64 bit desktops accessible over my home network?
If I put the Xen hypervisor on the tower, will it take advantage of the GPU of the tower effectively and run windows games well in multiple virtual desktops?
Will this configuration take advantage of multiple GPUs (if I chose to buy a 2nd or third GPU) configured with CrossfireX?
Do I have to buy a windoze license for each VDI to be legal? The kids games and school software all run on windows only.
Does anyone know of a VDI server that already does this, so that I don't have to build one . I would gladly pay a few dollars a month to use a VDI with some GPU horsepower to run games on.
Accepted AnswerGregory HallOffline0So basically, I would install Xen ... create a couple of virtual desktops and install Win7 64 bit on each Virtual desktop? I am not familiar with Xen, I have a basic understanding of how ESXI works, and I am assuming Xen is similar.
I have been looking at an app called splashtop that is a remote desktop tool that has good frame/second and low latency. But that will only allow me to connect one laptop at a time to the tower. On the performance issue, it is a question of the video cards. They need the drivers, and I would assume the drivers are windows based, not sure if the video cards are going to run correctly on Xen. I am wondering if anyone has run it on a machine with a decent video card. Most corporate installations doesn't care much about video cards.

There is also always lots of discussion on related to playing using Xen and VGA passthrough on email@example.com. You can post without being subscribed and can search via http://xen.markmail.org/

Accepted AnswerBruce vanNormanOffline0The following may not seem to have any bearing on your objectives. My goals are far less than yours. But, where I have gone, you will have to follow (and then some).
I am running CentOS-6.8 / xen 6.4 / virt-manager 1.3 all "off-the-shelf" packages from the CentOS repositories. My guest machines are work-stations which makes latency far more important than throughput. Additionally, the plan includes movies (MPEG-2) with surround sound and some audio processing (digital to analog to digital using some Burr-Brown hardware with USB interfaces). To this end, I am planning on using VGA pass-through which has very limited hardware support and pass-through USB.
So far, I have figured out that pinning a cpu core to DOM0 while limiting the vcpu count to 2 (HT threads). And, allocating all the remaining threads (6) to each and every workstation guest improves latency over the default settings. Next target is xen hypervisor tuning, where RTDS (Real Time Deferrable Server) seems to be the best approach.
The iron is a very quiet Super-Micro 5039A sporting a X11SAE system board, quad core 3.5 GHz Xeon processor with HT and 4 GHz turbo boost, 64 GiB DDR4 memory, and 8 TiB of RAID storage. So far, it is pretty pokey with it's HID response times.
