GPU Passthrough issue with HD7770 Sapphire Flex
- Thread starter mcflym
- Start date
seems very nice new feature ! will try to do a test if i found time this week or next one
if someone test it will be great to get some feedback too
just wait some days, it should be available soon in pvetest repository
Can you please post it here in this thread if it is available?
thank you!
yes, in git
https://git.proxmox.com/?p=pve-kernel-3.10.0.git;a=commit;h=33739cab6de3cb61b402a18df325cc567dafdc03
but not yet released in pvetest repository.
A first user report than gpu passthrough is working fine now,
but need qemu 2.0. (so you need pve-qemu-kvm from git too)

Hi, when will it be released in pvetest repository?
As soon as possible.

If you don't want to wait, why don't you build the necessary packages on your own? Just install latest proxmox as guest os so that you can build the git packages without touching your running machine. You can use the DEV Readme as general guide.
Hi,
pvetest repository is updated now, with all changes to support gpu passthrough
documentation is here:

Well,
sorry for the delay, when i try to start the VM i get the following error:
Kernel-Version:
Linux version 3.10.0-3-pve (root@lola) (gcc version 4.7.2 (Debian 4.7.2-5) ) #1 SMP Sat Aug 2 09:30:30 CEST 2014
Settings for VM:
lspci:
I have another VM where i passthrough a LSI SAS Controller without any problems.
Hmm, if i look into
you can see that the LSI Controller and the Radeon are in the same group?! And that causes the error?
How do i get the Radeon in another group?
Edit:
Installed new kernel:
same error and the devices are still in the same group :/

Hmpf,
if i start only my "Radeon-VM" the VM starts but i cannot connect via Konsole cause it says: "This VM has no graphic display device"
Does it mean that i cannot use the console if i passthrough a video card???
Edit:
i changed the VM config to
without the "x-vga=on".
Now i have a display via qemu, will see if i can use the VideoCard for my Steam Streaming Server
Edit 2:
I could install the radeon drivers without issues, will see how it goes on now.
But I still need the opportunity to run two VM (with the LSI Controller and Radeon Card at the same time)
Edit 3:
The next thing) ) ... the HDMI-Audio is shown up in the device list - is there a connected hdmi device needed to enable the audio?
Edit 4:
Well, this really f*** me up
If i connect a physical display to the card (with x-vga=on) and start the VM i can see the windows starting screen but then the display doesn't show anyting :/

For sure, this will the last post today!
My general question is:
Is it possible to use the VGA-Card as the primary card and the qemu/html5/vnc/whatever webconsole as the secondary card (only to manage the host)? I think if i setup a display in proxmox it uses it as primary display and Steam will use it too --> bad performance
I want setup a Windows Gaming Machine with Steam (as a in home streaming host).
Ist this possible?

Hi,
the problem is that the first device is the emulated vga, and passthrough device is second monitor.
Can you try this new qemu-server version ?
http://odisoweb1.odiso.net/qemu-server_3.0-18_amd64.deb
It's disable emulated vga (so no more proxmox console), but put passthrough device as first monitor.
Hi,
i'm so happy that you are responding
If i install this new qemu-server, the other VM will not be affected? And how can i manage my Gaming-VM? Via VNC (installed on the VM)?
thanks!
Edit:
I fixed the iommu-group issue with the help of XueSheng with the "pcie_acs_override=downstream"-fix!
I already have qemu-server: 3.1-30 (which should be newer?)

Ok, thanks, I'll put it in the proxmox wiki
Oh, I didn't see that Dietmar already push it to pvetest. So yes,it's the same version.
Hi,
to get the option working you need a patched kernel, without this patch it won't work! I hope there will be a release comming up which includes this patch?
And what i don't understand:
1. I did set up my Windows VM with the proxmox console (including gpu passthrough but without "x-vga=on" option).
2. Installed RealVNC Server on the VM
3. Shutdown the VM
4. Added the "x-vga=on" option
5. Booted up the VM but it won't come up to windows (Proxmox shows that the VM is on but no network-response)
In this scenario the VM is a PC without a monitor connected, right? Why it doesn't boot correctly? Maybe x-vga=on disable keyboard/mouse too? But I don't think so.
greets

Why do you want to passthrough your video card, if you don't have any monitor connected ?
