GPU passthrough issue on Win10pro
To preface this, i'm a Linux rookie, and a complete beginner at Xen/XCP-NG, so please be gentle If you need me to provide logs, etc please give me the code to bring those up. Thank you to everyone in advance. I've tried fixing this through research but i'm running into a brick wall with this problem.
I'm putting together a home server that I want to double as an editing workstation, and I'm having problems getting the GPU passthrough working. I've gotten my HBA card passed through without any hiccups, but with the GPU I've tried 2 methods so far, but i'm having issues with both. I'd appreciate any troubleshoot tips/hints/advice that could be offered. I've outlined the steps i've already taken below, as well as my system configuration.
Method 1 - using the built-in tool in XCP-NG center to prevent the host from using the GPU on startup, I have tried installing both the xcp-ng tools/management agent as well as the Citrix versions(On different installs of course, i've seen the issues that can happen with mixed tools) and I keep having the same issue where the AMD Radeon drivers install to 96% and then stalls. There is a notification in windows that says a restart is required, but when i restart it just hangs and i can't get Windows to boot any longer.
Method 2 - using CLI as demonstrated in the XCP-NG GPU and compute passthrough documentation section. When using this method (I tried to see if i could passthrough both the GPU as well as the HDMI audio) I get a notice from AMD Radeon drivers that it doesn't support the configuration.
System configuration -
AMD Ryzen 3700X
ASRock x570m Pro4
64GB 3200 hyperx predator
512gb Samsung 970 SSD
AMD Radeon 5500XT
Dell PERC H310 HBA flashed to IT mode for
6x3TB Seagate es.2 SAS Drives

Log output attached. thanks!
@r1 on the current setup i have (I've reinstalled everything multiple times to get back to square one) I've used the XCP-NG center gpu passthrough GUI, and I'm also using the Citrix managment tools on this particular install.
@SidneyMussburger in your BIOS, please check that your AMD card is not your primary display. Your onboard should be primary display and AMD card as secondary.
Any conclusion to this? Did you investigate your GPU’s integrated graphics as the primary card In your BIOS?
Is that a requirement of PCI passthrough? That it can’t be the primary GPU? I started a thread recently trying to debug a passthrough issue.. and finding this info I think it may be related. But my system has no onboard GPU. Can it not run headless? CPU is 1950X by the way. It does seem like dom0 is competing for use even when its supposed to be using the pciback driver. More info-
@trent234 I think system should run headless and Xen should be able to hide that device from dom0, can you reassure that BIOS is set to not use any display device?
