X299 PCIE Passthrough - I have finally arrived

Hello there Level1,

I am pleased to announce that after years of wishing I could do this and many failed attempts my new beastly machine finally works with pcie passthrough. I’m a semi advanced linux user, but never got this particular challenge off the ground due to hardware issues and things.

I have one question for you pcie passthrough pros out here though. I followed a guide for Fedora 31 I found on github, and everything seems to have worked fine. I was chasing a very bad performance issue for a while and figured that out just recently, but now I’m still losing a good bit of performance compared to native on some windows games.

I can boot into windows and run Rust at about 90 fps or so, and with nearly the same settings I am getting more like 60 or 70 in the VM. These aren’t the same windows install and there are some differences, but I see a similar issue in CSGO as well. The difference in CSGO is that I was getting close to 300 fps natively, but only just over 100 fps in the VM. Its completely playable so I don’t mind that, but Rust dips down low sometimes I do notice that. Besides, I’d like to think there is something wrong because I have a decent machine that should be able to push this game a bit better.

Here is some general info about my PC:
-I9-9900X
-X299 Aorus Master
-RTX 2070 super(guest)
-RTX 2060 super(host)
-64G Ram
bunch of nvme ssds, 3 spinning disks and 1 sata ssd.
I run Fedora 31 with AwesomeWM. Everything is using uefi to boot up.

I have seen where people wanted their XML file posted along with some outputs of certain commands. I will post the XML and the output of the lspci -knn just in case those are useful.

Thanks in advance for any input or advice.

Here is my xml:

Is single core boost properly applied in the VM? I’m thinking of a 10920X for my Passthrough setup.

You need to isolate and pin the cores, and use hugepages so the OS reserves memory specifically for the VM.

You’ve also only assigned 2 physical cores, so it’s performing only as well as a hyperthreaded dual core like the G4560.

I am not sure (assuming not)

Thanks, I’ll check into these as well.

I’ll give it a few more and see how it does (I thought I assigned 4 though)

Thanks for the input. I’ll get these addressed and see where I end up then.

Congrats!! It took me a good long while to start, figure out, and complete my PCI-E Passthrough project as well. Been running good for a month or two now. Very happy. I’m also running on the X299 platform and really looking towards an 10940X if they ever really are easily available. Driving 3+ hours to Microcenter to buy something I shouldn’t be in the first place isn’t very wife friendly! Especially during these times!

Hope all continues to go well for your setup.

Ya I’ve had this dream of being able to run all my games and just turn my head a bit and do some other stuff on my terminals or whatever in my preferred environment and all that. I don’t have to have split personalities anymore hehe. As much as Linux gaming has improved it still isn’t quite there yet. And games like Rust have taken a few steps back, hopefully that doesn’t become any sort of trend for other games.

I just built this box late last year so I doubt I will be doing any upgrading for a while. I did hesitate a bit because x299 isn’t “new”, but I’m impatient and didn’t want to wait for the next enthusiast platform to come out.

I wish I was near a microcenter. Closest thing I have is Frys (which is nice when they have things on their shelves)

@FurryJackman I did have a pretty good improvement in performance once I enabled the hugepages. I did that first before I set cpu affinity, but I did that as well. I think I am very near or perhaps even above native performance at this point. Thanks for the suggestions

Affinity is one thing, letting the VM know the IO threads (which 2 threads make up a single core) also improves performance. In virt-manager, you can’t set threads to let the VM interpret it as 2 hyperthreaded threads.

Best practice is to look at lstopo and assign IO threads based on which threads make up a physical core. You can only define IO threads using virsh and XML editing.

Well I did do this via virsh edit. I ended up using:
‘cpuset=“4-7”’ in the element. I found this on redhat site.

<vcpu placement="static" cpuset="4-7" current="4">20</vcpu>

Is this not what you were referring to?
