Do you know how fast the card is outside a VM so you can compare speeds?
I do not have experience with this cards performance outside of a VM so I can't make a comparison.
I am going to scale back the number of GPU jobs running because this card has one BIG heat sync (no fan) so I want to get a feel for what its temps might be. With 3 jobs running it is running at 60C according to GPU-Z.
I installed p-sensor on the UBUNTU VM and it only reports CPU performance. It seems oblivious to the temps for CPU etc. on the mother board.
Since you had such success, I of course had to go back and try it once more. And got exactly as far as before :(
Graphics card looks fine in device manager but when I try to crunch with it boinc gives the error message "GPUs have become unusable; disabling tasks" in the log.
So I swore about the unfairness of the universe, tore the GPU out of the machine and set it back in my workstation. I've done this so many times I'm afraid I'm going to wear out the PCI connector :/
After a while I did what I should have done in the first place: Google it !
Found some links, among them this one. First reply there have this gem: "Any version of BOINC can't crunch on GPU as Microsoft's Remote Desktop replaces the video driver with non-CUDA generic video driver.". And guess what? I used remote desktop to access the VM, and you didn't! They even recommend using UltraVNC just like you use.
So .. Tomorrow I'll give it Yet Another Go. Wish me luck.

I appreciate your frustration. I really do.
Here are some things that slammed me. I have an ASUS motherboard. They refer to virtualization in the document. It is defaulted to disable. So I enabled it. Still had problems, my MB document said nothing about VT-d. I even searched in an online document for this attribute and found nothing. Then one night I found a VT-d parameter in the BIOS so I set it. I also set graphics configuration to IGPU (I have built in graphics) and set "IGPU mult" to enabled. I throw this out because if just one bios setting is wrong your done before you start.
Also there is a requirement in Windows that you have installed Microsoft NET framework version 4 or better. Without this the drivers for ATI devices will not install successfully. Also I believe it was a requirement something else but I cannot remember at this point.

Here is a link to the actual remote product i used. Get both the server and the client. Simple install. Free to try and you can continue to use it after its trial expires, but with less functionality. I can only thank Usoft for not providing me their remote desktop solution in the distro I have. It would have been like running low hurdles without a jock strap. [thwap, thwap]

I wish you success. I have put together a README on XenServer on my site. It is not complete but later when I get it "done" if you want to give it a read maybe we can come up with a composite "readme" on how to do this painlessly. I should point out I am retired with time and that you are probably a working guy with family. So if you were willing great if not I understand. I would also be willing to cut/paste it here if that is acceptable by forum standards. It does not have to be on just my website. Of course having said all of this I am assuming that others would want to do this.
Great you guys figured this out! Now what we really need are comparisons to native performance.
MrS
I was holding off on responding to your post because wanted to see how these GPU jobs progressed. Like I had said earlier to Logforme I do no have experience with this card (AMD Radeon HD 6450)outside of a virtual machine.
Yesterday when I got my first GPU WUs I was optimistic but as of right now I am only ~33% of my way through the original three so my optimism is fading. Elapsed time is showing ~21:30 hours with a long way to go. I am crunching Binary Pulsar Search (Perseus Arm Survey) 1.39 (BRP5-opend-ati) WUs. I would like to believe it is this card and that it's performance would be the same in an "unvirtualized" world but I can't. Does any one here or in another project have a feel for how this card performs?
[Edit] I checked the stats for this machine at E@H and have not received any credit for these GPU work WUs. At this rate I am projecting 3 days to complete these 1st three GPU WUs.
Setup during this test was a virtual Windows Server 2008 machine with 4 vCPU running 3 simultaneous GPU tasks. At the same time another Debian VM was running a fairly CPU intense job.
Compared to native Windows 7 machine with a 4 core CPU with hyper threading running 3 simultaneous GPU tasks and 3 simultaneous iGPU tasks.
I'll let the effect of the Debian VM cancel out the iGPU jobs for simplicity :)
40% stings a bit. But at the moment I think I'll keep the GPU in the VM and play around with it.
Big thanks to Robl and the rest who helped me through this ordeal :)
in the above example the Native data point 3024. What is it referring to? Where is this info located? [EDIT] is the 3024 a posted "run time"?

The performance of my Radeon card is most disappointing. 30 hours into 3 jobs and only half way if I am to believe the "status/performance" bars. What I really need to do and the thought scares the crap out of me is to replace the radeon with a NVIDIA 650 TI. I have two. This way I could do a comparison across a Win7 VM and an Ubuntu box (not a VM). Courage. If a 650TI on a VM drops down significantly then I would have to rethink virtualization from a crunching perspective.

Cut & paste is fine ... congrats on UOTD too! :-)
