I can passthrough M60 fine so I don't think Quadro can't passthrough. Its likely you installed the wrong driver.

RE: Hiding hypervisor from guest to prevent Nvidia Code 43
@r1 said in Hiding hypervisor from guest to prevent Nvidia Code 43:
@olivierlambert @imtrobin I had worked on CPUID for exposing temperature data of CPU to Guest (Dom0). May be we can use same.
# cpuid | grep -I hypervisor_id hypervisor_id = "Microsoft Hv"
Is this the one which should be hidden?
I'm have no idea if that is enough, but maybe. How can we try this? For kvm , they do this

do you have a link to which one you are referring to?

RE: Looking for a temporary test host with a nVIDIA GPU
Not sure which one you are referring to, I'm referring to this

I think you can find it on GitHub, I don't remember but I googled a bit about the error returned by the driver in the VM and found the patch
It's been reported the patch is working on Xen, but I couldn't get it to work on XCP

RE: Looking for a temporary test host with a nVIDIA GPU
I have a M60 if you need me to setup. It supports passthrough.

Thanks Oliver,
Sadly, ATI is being going downhill since AMD bought them over.

RE: Hiding hypervisor from guest to prevent Nvidia Code 43
From the github post, it seems the blacklisting the GPU works, which is similar to how kvm does it, without modification to Xen works?

RE: Hiding hypervisor from guest to prevent Nvidia Code 43
Actually, there are patchs for Xen, and it is working with Xen with driver patcher, but it doesn't work on Xenserver/XCP sadly

https://lists.xenproject.org/archives/html/xen-devel/2016-07/msg01713.htmlI'm not familiar with Xen code base (I took a look, and ugh) enough to know where to apply the hiding, but I don't think it should take months for someone familiar with code base.

RE: XCP-ng GPU Passthrough - No GPU found
@jmccoy555 You got nvidia GPU working in VM?
-
RE: vGPU - which graphics card supported?
vGPU require drivers on xen , which will need to work with Nvidia. Unlikely you can get it work as an open source. If you can get passthrough working, I will be very happy.

How different is XCP-NG from Xen
Hi, how much difference is xcp-ng differing fron Xen, other than xenadmin tool.
I'm asking this because this patch works for Xen, but not for XCP-NG

RE: XCP-ng GPU Passthrough - No GPU found
Hi, so some people have been able to do it

RE: XCP-ng GPU Passthrough - No GPU found
In KVM, I need to do these
- turn on cpu hidden state
-
Assign the gpu to vfio directly (I guess we may not need to do this here)

Blacklist the nvidia drivers like this

RE: XCP-ng GPU Passthrough - No GPU found
I'm talking about GPU Passthrough, not vGPU. The GPU is passthrough fine but the nvidia driver results in code 43, meaning the driver detected it is running in a VM.
KVM bypass this by spoofing the VM, and it works, so can XCP do similar?

RE: XCP-ng GPU Passthrough - No GPU found
KVM is quite easy to spoof the VM so the nvidia drivers work. Is it possible to do easily for xcp?
