@andriy.sultanov I finally got around to fixing my capture card and I gotta say, it's a real pain to be using both methods and doesn't feel "correct" especially when there are warnings about possibly losing dom0 configurations after updates and the knowledge base saying that the old hide PCI from dom0 method is now considered obsolete. Perhaps the best solution would just be to provide users with a CLI command that would add that particular device to the xl pci-assignable-list if it doesn't fall into classes 01XX, 02XX or 03XX. Because I had added my GPU to my VM using the webUI, but then I also wanted to add the capture card through the console, but it appears that in the end you basically need to undo what's been done in the webUI and do it all through the console, otherwise you'd add the capture card manually with command line and then that would remove the GPUs... So I think some sort of manual override is necessary, even if it's a CLI option and then once that's done we could go into the webUI to enable it once the device has been marked as safe to passthrough.

I don't think you need the --unit declaration. Try serial --port=pci,0b:00.0 perhaps?

@Pyroteq said in Easy way to find a failed task?: It seems as soon as you refresh the page everything disappears. The Tasks page only shows logs while you're viewing it. Afterwards I think they get recorded to the Logs, but if your system fell asleep XO wouldn't know what happened. Besides the connection getting dropped and I don't know if that would get recorded.

That's weird, never heard about this option to be needed to make it work, does it ring a bell @fohdeesha ?

@olivierlambert Unfortunately they don't offer a guide, just a mention of it working. https://docs.citrix.com/en-us/citrix-hypervisor/graphics/hv-graphics-config.html Citrix Hypervisor supports Intel’s virtual GPU (GVT-g), a graphics acceleration solution that requires no additional hardware. It uses the Intel Iris Pro feature embedded in certain Intel processors, and a standard Intel GPU driver installed within the VM. However, they don't actually offer a guide on HOW to set this up besides offering some tips on how to setup BAR in the UEFI settings to change how many vGPU's it will support. I've enabled Above 4G Decoding, Re-size BAR Support and set the Aperture Size to 512MB but that doesn't seem to enable the vGPU options XCP-ng Center or XO. I'm assuming I need to enable it manually on the underlying OS before XCP-ng can see it. Note that the Intel GPU pass through is GVT-d NOT GVT-g. If you use GVT-d (AKA, just your regular PCIe pass through) obviously then I wouldn't be able to use the GPU for the the XCP-ng console on the machine itself. I'm comfortable on how to set that up but I really need the console available on the hypervisor for my use case. This video (in German) demonstrates setting it up in XCP-ng center. https://www.youtube.com/watch?v=FW9TPMrdTYc
