Trying to resend this mail! TO PASI Xen 4.3.0 is used without any patch. ======================================= - VM = Linux 32/64: I can set RAM > 3GB. Playing games, watchings videos etc...All is fine! - VM = Win 7 64: I can set RAM > 3GB. Playign games, watchings videos etc...All is fine! - VM = Win XP 64: if I set RAM > 3GB then the VM get slower. VM gets slower once NVIDIA driver is installed and that I restarted thsi VM :(. I tried a couple of things but unfortunately I was not to fix it. Setting RAM <= 3GB for Win XP 64 I had a nice VM to play games, watch videos etc... XP 64 is a bit pain! GTX480/Quadro 6000: ================= As Gordan said it is not doable to restart the domU (well known issue!). But the soft-moded card could be interesting for playing games . I test Gordan's method on two differents cards and it works pretty well! If restarting dom0 is not a problem then here is a (not-updated) link http://www.davidgis.fr/blog/index.php?2013/09/18/969-xen-430-vga-passthrough-gtx-480-soft-moded-to-quadro-6000 GTX680/GRIDK2: Gigabyte GV N680OC-2GD ==================================== With GTX680
hard-moded I "tried" GRIDK2 -- not K5000 --. If you have and_only_if you have a Gigabyte GV N680OC-2GD there are two SMD resistors to remove as explained by reading two messages http://www.eevblog.com/forum/chat/hacking-nvidia-cards-into-their-professional-counterparts/msg207550/#msg207550 http://www.eevblog.com/forum/chat/hacking-nvidia-cards-into-their-professional-counterparts/msg207795/#msg207795 Just take of where resistors are
located in the image below (I am not the author of this image!) http://www.eevblog.com/forum/projects/hacking-nvidia-cards-into-their-professional-counterparts/?action=""> Removing SMD resistors could be done without any soldering iron :). Those components are the easiest to remove. It
could be done using tweezers and a fire source. I did it using a knife and a candle (old school). For K5000 a soldering iron is required! (not tested!) ========================================================================================================================= TO GORDAN GTX
680/GRIDK2: DL-DVI/DP/SL-DVI ================================ I don't really if the following test will reply to your question but here are the connectors I tested on my card http://www.davidgis.fr/download/GTX680_Outputs.jpg 3 Connectors have been tested. I will try here to share a complete/idiot test I did. Here is a minor issue I found Output A=> DVI-I Connector ---------------------------------------- The dom0 has just started. There are two VMs (one XP 64 and one Win 7 64) Start XP 64...OK--> Screen works! Stop XP 64...OK--> Screen works! Start XP 64...OK--> Screen works! Restart XP 64...OK--> Screen works! Stop XP 64...OK--> Screen works! Start Win7 64 ...OK--> Screen works! Stop Win 64...OK--> Screen works! Start XP 64...KO ---> Black screen!!! xl destroy for this VM. And VM Win 7 64 can start properly...Screen works Output B => DVI Connector ------------------------------------- The dom0 has just started. There are two
VMs (one XP 64 and one Win 7 64) Start XP 64...OK --> Screen works! Stop XP 64...OK--> Screen works! Start XP 64...OK--> Screen works! Restart XP 64...OK--> Screen works! Stop XP
64...OK--> Screen works! Start Win7 64 ...OK--> Screen works! Stop Win7 64...OK--> Screen works! Start XP 64...KO ---> Black screen!!! xl destroy for this VM. And Win 7 64 can start properly...Screen works Output C ==> mini HDMI -------------------------------- The dom0 has just started. There are two VMs (one XP 64 and one Win 7 64) Start XP 64...OK--> Screen works! Stop XP 64...OK--> Screen works! Start XP 64...OK--> Screen works! Restart XP 64...OK--> Screen works! Stop XP 64...OK--> Screen works! Start Win7 64 ...OK--> Screen works! Stop Win7 64...OK--> Screen works! Start XP 64...KO --> Black Screen. xl destroy for this VM. And Win 7 64 can start properly...Screen works Conclusion: whatever the connector is it seems doable to restart XP 64 ( no switch to Win 7
64!) For GTX480/Quadro 6000 ==================== The latest VMs I set up were a VM Win 7 64 and a VM Win XP 64. ( = 2
VMs) -
gfx_passthru=0 while setting up the VM -- before installing NVIDIA
drivers. While VMs were setting up I used (native) VNC connection.
(vnc=1) - gfx_passthru=1 once NVIDIA driver was installed. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
