        I tried for a bit using HD youtube clips, but I couldn't be sure whether DXVA was actually being used or not.


        After doing a bit more research, it seems that DXVA is a very complicated topic, and whether it is used or not depends on the GPU hardware, GPU driver/software versions, decoding software installed, and the individual video file itself.


        There is an in-depth discussion here that revolves around a utility called DXVA-checker, available here.


        Here's the output from the tool (DXVAChecker64_2.5.0) when run on my system:


        AMD Radeon HD 6800 Series

        If you click on the big "Check for DirectShow / MediaFoundation Decoders..." button along the bottom of the dialog, you can browse for a test clip.  The program should then analyze the clip and present a list of possible decoders to use.  If you don't see anything come up in red, then the clip will likely not play using DXVA acceleration.  If you do se a decoder that is listed in red, click on the arrow to the left and choose either "play" or "benchmark".


        I'd be happy to try some other applications on my system, but I might need some help getting the specific decoder / application chain set up on my system.

          Hi somedude1234,


          your postings on this topic are greatly appreciated.


          Can you confirm that the Radeon HD 3450 also had fully working hardware acceleration when passed through, as you only mentioned gaming, dvxa etc.. with the 6850 card?  Im just looking for a card that would work with basic 2d/3d directdraw/direct3d hw acceleration and the 3450 would be a nice and cheap way of achieving this.


          Would you also be able to advise of which ATI driver version you used, in case that turns out to be important, or have you used multiple driver versions successfully?


          Many thanks in advance.

            Hello all,

            I have a Dell Optiplex 780 which supports VT-D, and I'm trying to get my Sapphire Radeon HD5450 to work with vmdirectpath.


            As far as I can tell, there are no issues passing the device through to the (Windows) VM guest. With no drivers installed the guest boots fine and can see the device, the ATI setup program and windows itself recognise the PNP IDs, and match the 5400 series driver accordingly.


            However, once the drivers are installed,  I get a BSOD with an ATI DLL "driver in infinite loop" on restarting.


            No errors within ESXi/VI client.  I have the memory reservation matching the allocated memory, and it's <2GB.   The ESXi console video signal drops on VM boot as expected.


            What is the best strategy for me here - should I shop around for other video cards to try?  is there any merit in trying a radeon 4550?


            Or are there any other ways I can work around the ATI driver issue with some other drivers perhaps?


            thanks for any ideas

              The closest I got to it working was with an nVidia GeForce 7200GS but that also gave the "Driver stuck in an infinite loop" BSOD with nv4_disp.dll.  Tried it both on an xp 32bit and win7 x64 vm but same regardless.


              The driver used had an impact.  I tried various ForceWare versions, but the only that was closest to working was the 181.22 version - this installed, card was listed in device manager with "this device is working properly" status, and I could see it in the display control panel, but as soon as I enabled the monitor connected to it to extend my desktop onto it, the VM hangs.  I also tried disabling the vmware svga virtual adapter and this made no difference.


              I also tried an ATI FireGL V3100 and it gave various BSODs too.  I have just bought an ATI Radeon HD3450 on eBay and am also borrowing a friends ATI Radeon 2400HD so im really hoping I find some success with one of these.  I will report back and let you know.

                OK, just spent the last couple of days experimenting with my friends ATI Radeon HD 2400 Pro and Im happy to say it works very, very well.  I have been able to get vga passthrough working with this with zero issues, no BSODs, no crashes, no hanging, pleasantly solid and reliable.  Direct3d acceleration, DirectDraw, movie playback, youtube hd via flash (with and without hardware acceleration enabled) all works first time.


                On another note, I thought I would share my reasoning behind looking for vga passthrough, as it will certainly not be the same as anyone elses, I suspect


                My experiment was to see if I could virtualize a windows pc for the sole purpose of running retro oldskool emulators (such as zsnes, kega fusion, MAME etc..) at native sub-vga resolutions out to an old CRT television via a VGA-to-RGB scart cable.  To achieve this on a normal physical pc is complex enough, as it requires very accurate display timing software configuration via the use of an application called PowerStrip.  To have all of my existing PowerStrip interlaced and sub-vga progressive resolutions working within the vm via vga passthrough, im seriously surprised and amazed it works, given how sensitive the video output is to very small frequency variations.


                I have just received my Radeon HD 3450 today (£12 via eBay!) so I will test that next and let you know what my findings were on that, but for the meantime I think the HD 2400 Pro is a no-brainer for anyone wishing to experiment with vga passthrough as its such a cheap card.


                For reference, my config is as follows:




                ESXi 4.1u1 + all latest available patches

                Asus KCMA-D8 Motherboard

                2x AMD Opteron 4180 cpus

                32GB DDR3 RAM




                Windows 7 x64 (fully patched)

                2 vCPUs

                2GB RAM


                VMDP Devices:

                1. ATI Radeon HD 2400 Pro PCIe 16x (works great)

                2. Creative Audigy 2 ZS PCI (analog audio output is shrill / crackly, but digital SPDIF out is fine)

                3. NetMos / MosChip RS232 (1x DB25 2x DB9) PCI Card (works great)

                4. VIA 4-Port USB 2.0 PCI Card


                Video Driver Catalyst 11.6 video drivers (as of this posting, the latest available).






                Update: 21/07/2011


                Just an update to say ive tested the ATI Radeon HD 3450 and it works every bit as well as the 2400 Pro card.  Looks like ATI is the choice to make when it comes to vga passthrough.  I also added a VIA 4-port USB PCI card - this is detected as three individual PCI devices, 2x usb 1.1 and 1x usb 2.0.  Unless all three are passed through, the vm fails to boot.  Only the usb 1.1 ports work in the vm (tested ok with a usb mouse and usb keyboard attached), the driver fails to start for the usb 2.0 controller with an Error Code 10 in Device Manager.

                  Hi BAM279 Glad to see it worked for you,


                  I too have some sleepless nights trying to get this to work.... I got from ebay a matrox g200 PCI as I saw the somedude had that built in in his motherboard.

                  Since I installed the Matrox PCI for the Host VGA, I don't get bluescreens and all my dirvers after install work: nVidia 6200 and 8400GS and ATI HD 4670

                  (work... they show ok on the device manager)

                  But I never got it fully working, best I got on one reboot, was to have on Linux the physical screen showing a console (text) and working 100% (text) but not graphics.... never managed to do the same ever again... it works best on XP 32 with my ATI 4670 I see the two external screens of the card on display but as soon as I enable them I the VM freezes!!


                  With nVIdia cards I sometimes manage to enable the external screen, I can see the mouse going over to it but if I move a window to it it will freeze...



                  It's so close......


                  Can you please tell me what is the exact brand and model of your ATI 3450?

                    BAM279 Novice



                    my specific brand 3450 was one of these: http://www.sapphiretech.com/presentation/product/?cid=1&gid=3&sgid=307&pid=164&psn=&lid=1&leg=1 .


                    This card also has onboard HDMI audio which is passed through the DVI port and this is indivudlaly listed as a passthrough device in ESXi.  I have not tried it as I dont have an HDMI tv, and im passing through my Audigy 2ZS for audio already anyway, but it might be of interest to you if you do...  I have also just passed the ATI card and not passed this HDMI audio device and thankfully the card still works perfectly on its own, which means you wont be forced into having to pass this extra device through in case you are tight on free passthrough device assignments (max of six).


                    Similarly, the Audigy2ZS has three passthrough devices separately listed, the audio card, the gameport and the firewire port - and thankfully once again you can pass just the audio card device through on its own without the others and it still works perfectly (altough as previously mentioned, analog output is horribly distorted, you must use digital out, which is perfect)..


                    I have been continually using my new vm with vga passthrough without issue over the past few days so it looks like its fully stable   I just wish I had been able to get my nVidia 7200GS to work, as it is a bit better for custom resolution output than the ATI, especially with sub vga modes.  Maybe with a bit of luck, someone will find a cheap nVidia card that does work

                      Sadly, there are still some drawbacks with those old cards.

                      - You cannot get True HD audio passthrough

                      - DXVA is older and not as complete as in the new one


                      From what I understood from this thread, AMD series 2,3 and 6 seems to work with DXVA where the serie 5 don't.


                      I will manage to buy a HD6450 to see if my guess is correct, if it works it may be an excellent and inexpensive card.


                      According to the patchnote, some good is also to be expected from the upcoming version 5 of vsphere.

                        I'd like to thank everyone who experiments with vga/gpu passthrough and posts the according system specs! this encouraged me to try it on my system too. here are my specs and results so far:

                        (off topic: I'm still looking for a HD Tune bench with the same SDD model and the C206 as it doesn't perform as well as it should. Any hint is greatly appreciated!)

                        I tried different driver versions and always used a fresh install. I'm also curious and just ordered a 6450 (Sapphire Radeon HD 6450 512MB PCI-E (11190-00-20G) w/ DisplayPort). I'll post whether it works or not as soon as I get my hands on it ^^

                          Hi Jsnow,


                          Regarding this:


                          ATI Radeon HD 4850

                          • worked neither as primary nor secondary (BSOD atikmdag.sys)



                          I had this happen once upon initial passthrough of my ATI HD 3450.  Try the following:


                          1.     if your ATI card also has the HDMI audio, pass it through as well, just until you get the catalyst driver installed - it can then be removed again


                          2.     Remove any other passed through devices to the vm temporarily


                          3.     This BSOD is a known issue with the 11.6 driver in general (from what ive read online, so its not necessarly being caused by passthrough)


                          4.     Boot into safe mode, disable the ATI card in device manager, reboot normally, re-enable the card, then try installing the catalyst driver again


                          Good luck!

                              fresh install - nothing passed through
                              installed vmware tools - rebooted, all good -> shut down (created snapshot)


                              configured both, gpu and hd-audio devices for passthrough:

                              received  popup "No AMD graphics driver is installed, or the AMD driver is not  functioning properly. Please install the AMD driver appropriate for your  AMD hardware."

                              installed VMware Tools => reboot

                              boot into normal mode, windows logo and BSOD atikmpag.sys


                              for now I give up and wait for the 6450 to arrive...


                              something weird though, after each start or reboot, the vga cooler  goes full speed 4-6 times in ~1s intervals, on shutdown just 2 times
                              1s on, 1s off, 1s on, 1s off ... and so on - nothing serious, just thought I'd mention it

                                I do want to know does anybody can VMDp the Intel integrated GPU as primary or secondary output?

                                I feel interest in it.

                                  maybe someone can try an HD 3000 but I have a feeling that it won't make a difference. Still waiting for my 6450 though...
