Hey everyone! Reporting back in with good news! I was able to get my Sapphire RX 480 Nitro+ OC 8GB to pass on over to the other side! Sounds morbid, I know! Here's everything I did, start to finish, for anyone who may be trying to pass through a 480 on Proxmox or similar OS and having...

Hello all! Reporting in once again! I can confirm that the card was part of the original problem. I RMA'ed it and got a replacement in the mail today. I installed the new card and checked to make sure my host machine (now running Proxmox 5.0 Beta 2) was booting via UEFI. All good in the...

Another update... I feel very stupid. My Proxmox installation was using the legacy BIOS. I'm not sure if this is important or not but now my host is running the 5.0 beta and is booting using UEFI instead of BIOS. Another interesting thing that I was hoping someone would be more of an expert on...

I am not certain, but I will check. I'm pretty sure I do. When I mentioned all of the devices saying Legacy instead of UEFI I was talking about my PCIE devices...still that is a little odd. I should check that. I've been actively working on finding a solution. I am down to a few potential...

Sorry to spam the post but I figure if I do resolve this issue, I'll have some decent info to add to the wiki. Here's something interesting. Someone over on the redhat mailing list has had this exact same issue. The recommendation there was to take multifunction graphics cards and pass their...

Curioser and curioser. Here's what I've got now: I disabled Windows Firewall on the guest and checked to make sure remote desktop would allow connections and now I can remotely access the machines after power on when the x-vga=on option is set. So I know for a fact the machines are powering on...

Further troubleshooting before I try the second card. I used the qm monitor to look up the information about the guest pci devices. Lo and behold the card is being passed through and recognized as a VGA controller when I enable the x-vga=on option. Bus 1, device 0, function 0: Audio...

I actually thought to try that last night. Everything appears to be working well enough but no luck on it fixing the passthrough. Working the same as it was unfortunately. I have an extra GPU laying around, I'm going to try dropping a different one into the 1st PCIE slot of my host and then try...

Hi dcsapak! Thanks for the reply. The ROM I'm using is here. It says it has UEFI support. This ROM is both flashed to the card and I've tried using it as a ROM file. I'll test the GPU with x-vga=on using SeaBIOS and report back later on. I believe when I originally tested it using SeaBIOS I...

It sounds like we're having similar issues. The wiki page has a couple different settings. Their host GRUB line says to include amd_iommu=on and that if your system doesn't support iommu yet you can allow unsafe interrupts. Not sure if either of those would be helpful but you could always change...

Hi all! I'm just now taking my first real foray into Proxmox and I'm loving it so far. But I could use some help. Some of the technologies at play here are still a little foreign to me. I apologize if I'm a little wordy here. First some details: Version: Proxmox VE 4.4 Hardware: Supermicro...

A while back I posted about wanting to do OVMF passthrough to leverage some powerful GPUs I have set up in a whitebox server. I'm back! Just to provide a project update, I'll be setting up these "gaming VMs" in the coming weeks. The biggest issue I'm noting now is that SPICE doesn't support USB...

I think I found my solution, which is cool because even though I know RDP is working alright, I want a better answer. I also would like to integrate as many of the features of SPICE as possible into my finished product. I'm looking at the newer AMD and NVIDIA cards, and apparently they have...

Thanks for the reply! I'll have to dump the rom then. That's a bummer about using a USB adapter, but I mean, I know what I signed up for with this one. No such thing as an easy fix. About Spice though...I hadn't even noticed that! It looks like the QXL driver is necessary, but I'm going to do...

Hi! I've been messing around on reddit's homelab page for the past couple months, and eventually the idea came to me that I wanted to build a ridiculous VM host so that my roommates and I can game together on the same machine. It was a huge pain in the ass, but I have CAT6 Ethernet run...
