Spending time on GPU passthrough and seeing it evolve brought forward a topic of people running VM in passthrough with direct output to the screen attached to the GPU. Obviously, this had me wonder if it would be possible to have this one GPU output to multiple screens directly, this card has 1...

Had a brief look on the rainway website, they are very secretive at what it actually is. In a way i think they actually run the game on their servers and stream the screen thru a high speed CDN of sorts. Does this really run locally ?

this is a remote desktop software so, no. if gaming is your thing https://looking-glass.io/wiki/FAQ

eh, thanks for the thanks i guess :) i'm documenting it in my redmine so i don't forget again

install nomachine.com on both the VM and the machine you use to connect to the server

Well, proud to day i have all that and more (msw, osx, lnx) with a far more modest setup. I never get how all people have all the good stuff and I , as a professional, fail to find money for it :D What do you mean with snapshotting ? This is built-in, no ?

Impressive machine :) i'm stumped as to why kvm=off works without performance penalty, things change, maybe it is not critical anymore in the way it used to be.

are you sure you're running proxmox ? maybe you installed with grub ?

no in my experience but i may have altered the outcome with making this more complicated, what does your /etc/kernel/cmdline look like ?

interesting, you actually have output sent to two physical screens ? I'm curious, can you share how you do that ?

do you really need to add kvm=off ? that kind of kills all performance in the VM

kvm=off should really be a last resort just in case, you can only use one GPU with one VM at a time, somehow i had the impression you were trying to do 2 VM 1 GPU considering you appear to use an amd chipset (x3?0 x4?0 x5?0 ?) you could try, consider to put iommu first instead of amd_iommu...

well, no problem there i guess. don't be distracted by messages too much.

can't say for output to screen ? no, not to my understanding, this is exclusively because of boot time parameters video= / efifb= / nomodeset to have output to screen you may also need to set the VGA output to not use virtio i guess, i'm happy with nomachine so i did not try more first check...

please, let us know what makes it work :)

i'm not sure you understand why you needed GPU passthrough :D like i said, try nomachine.com (free version works fine) unless it is for gaming this will work just fine i accidentay had this working at one point, from memory i'd say, experiment with nomodeset, video= , efifb= by changing the...

(beta) Agesa version of summer 2020, works like a charm. As it is running today the GPU scores higher than systems not running in a VM :) i think i actually reinstalled proxmox due to the many weird things going on, as i had also upgraded ram i had no clue what caused the issue really what i...

ehm, what do you want to do with the display ? if you're trying to make it work on the physical display, that is possible i think i assume not using nomodeset should fix that, if i remember well this is not an ideall approach, i started using nomachine for remote desktop as it is GPU accelerated

thanks for sharing, initially i had similar issues when arriving at Agesa 1.0.0.6, on an x370 motherboard, what is did was simply reset the bios by using the jumper on the motherboard, then reconfigure the bios I'd try again and rebuild the cmdline and pass through configuration from scratch

well, it is unfortunate, that is sure. know that if GPU passthrough works it looks like the system is hanging, you should be able to access it over ssh typically a bios upgrade does not require configuration changes on the os/proxmox when booting, press ESC at the bootscreen and review the...
