GPU Passthrough issue with HD7770 Sapphire Flex

[spirit]

I want to set up a Steam Streaming Server.

Oh ok, should work I think.

5. Booted up the VM but it won't come up to windows (Proxmox shows that the VM is on but no network-response)

can you connect a monitor to debug it ?

Okay,

i uploaded a video about whats happening...

Windows Boot-Logo comes up and disappears then nothing happens... the monitor is on and receives a signal (--> no standby)

The Video Card has 4 video outputs, i am connected to DVI (i tried both). Next week i can test hdmi - i don't think it will change anything because if the desktop comes up on another output the VM should be reachable via network.

Damn, this is super strange.

All seem to be ok (bios display , windows boot).
Maybe it's something related to the windows drivers ? But this is strange that you don't have working network.
I'll try to find some informations abou this.

In my opinion the start-screen disappears a way to fast.

Maybe i try to set up another windows machine with x-vga=on from the beginning.

Edit:

I'm starting a new installation right now

Edit2:

No issues until now... see the windows desktop... installing vnc right now

Edit3:

Hmm, after some minutes there was a flickering on the monitor and it's gone black... restarted the VM and could login, but few seconds later the screen turned black, too.
Now i am at the same point as the other VM.

Gonna try Windows 7 now

Edit 4:

It seems to me that the Windows 7 VM runs very good (no flicker and black screen) BUT after i installed my catalyst driver i got blue screen after reboot
Will try another driver version

Edit 5:

Still BlueScreen with a different driver. I have no ideas anymore

BlueScreen Message:


usual behaviour that the Videocard can dropped out the system like a USB-Stick?


Edit 6:

Installed only the driver without the amd crap, same problem

Should I try a NVIDIA Card?

Edit 7:

Ordered a Geforce GTX750 TI today... will see what kind of problems i get with this card

Update:

Got my 750TI today and it works now!

Great to known

Do you have used some special kernel options - iommu tuning ?

I'll try to keep the wiki updated with differents users setups.

Hi,

nothing changed in my setup.

I still have the "pcie_acs_override=downstream" patch "active".

Hmmm,

pci express passthrough works over all lanes or just one lane? (pcie x1)?

because:



looking at the info on https://bbs.archlinux.org/viewtopic.php?id=162768 tells me that x2,x4,x8,x16 are supported :/

and GPU-Z tells me:



so everything is fine? fyi: the MB supports x8 max

But only pcie v1.1 not 3.0?

After restart i got 3.0???

Hi!

I am having the exakt same problem with an ATI 280x.

When I enable x-vga the console says "This VM has no graphic display device" but on the screen connected it shows the image. I can move the mouse through the console but keyboard ins't working.
I am using win 8.1 x64 and when it goes in to repair mode it does not hang, I idled there for a few hours yesterday. As soon as windows starts to load a driver for the card (at least thats how it seems since it does not hang in repair mode) it crashes and reebots.
The only difference being that I see the crash screen.(compared to the video in the thread)

I have no other PCI-e device attached to my Proxmox.
Removed the x-vga, windows now finds a ATI device I installed the drivers and enabled x-vga again same result.

Is there hope for using passthrough with an ATI card?

Hi mcflym,
I'm trying a very similar thing and I'm using GTX 780 Ti cards but I couldn't couldn't get rid of "Code 43" in the guest OS yet.

Do you use the 3.10 Kernel from pvetest?
And could you post your cmdline, blacklist, VM's .conf and lspci please? (And if you made any other related changes, those as well)

Also did you compile anything yourself or update anything?

This would help me A LOT.
