It seems to have worked. I can see the device in the guest now: sudo lspci -v 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Caicos PRO [Radeon HD 7450] (prog-if 00 [VGA controller]) Subsystem: ASUSTeK Computer Inc. Caicos PRO [Radeon HD 7450] Physical...

Thank you for the information. Unfortunately, something is still wrong there. When I chose "install" (not graphical install) in the Proxmox VNC, this happened: I changed the Display to default and removed the serial0: socket and then I got this: Is this the right way or do we need the...

Yeah, as mentioned in the beginning, I just need the R5 230 passthrough, so other progammes can see/use the GPU (driver), but it is not used to really give output to a monitor. One question though, does the GPU passthrough always work only for one instance/VM?

I can try to use a different image, but I cannot verify anything with a physical monitor. My host/server is around 50 km away in a data centre. :) So, I guess, I have to do a fresh installation of the Debian image without graphical (as it was before)?

Alright, this is the rom file size: ~$ ls -lah /usr/share/kvm/ total 16M drwxr-xr-x 5 root root 62 Nov 28 01:28 . drwxr-xr-x 113 root root 113 Sep 28 18:12 .. -rw-r--r-- 1 root root 64K Nov 28 01:18 vgabios-asus-r5-230.rom I changed back the hostpci0 to hostpci0...

Alright, this is it where it is now: vega@rakete:/$ sudo journalctl -f -- Logs begin at Sat 2021-11-27 18:23:33 CET. -- Nov 28 01:33:51 rakete pvedaemon[7923]: start VM 103: UPID:rakete:00001EF3:00276797:61A2CE6F:qmstart:103:root@pam: Nov 28 01:33:51 rakete pvedaemon[3190]: <root@pam> starting...

Yes, the server has only this one GPU, unfortunately. Also, yes, the vfio-pci 0000:09:00.0: No more image in the PCI ROM message came again, even when starting with OMFV BIOS and IDE2 (DVD-ROM/Image) chosen as first startup device.

Okay, changes on host are active now, too: ~$ sudo cat /etc/default/grub GRUB_DEFAULT=0 GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR="Proxmox Virtual Environment" GRUB_CMDLINE_LINUX_DEFAULT="quiet iommu=pt amd_iommu=on video=vesafb:off video=efifb:off" GRUB_CMDLINE_LINUX="root=ZFS=rpool/ROOT/pve-1 boot=zfs"...

Alright, I removed the hostpci0 entry on the guest in the Proxmox webgui and then I was able to reboot the VM and reach it again. I changed this: ~$ sudo vi /etc/default/grub GRUB_DEFAULT=0 GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`...

Oh, thank you, I understand. So, I added what you mentioned, but somehow I cannot reach the guest remotely (using SSH) anymore. This is weird. It looks, as if the VM is not booting properly. These are the settings from within Proxmox webgui: The Proxmox webgui console shows this:

Okay, I changed vfio.conf back to disable_vga=1 and restarted the host. ~$ sudo cat /etc/modprobe.d/vfio.conf options vfio-pci ids=1002:677b,1002:aa98 disable_vga=1 Also, I changed in the Proxmox webgui the vga/display setting to display: none for the guest. Yes, this is the complete...

Thank you for your reply. Alright, I just changed the disable_vga=1 to vga=none and rebooted the host. ~$ sudo cat /etc/modprobe.d/vfio.conf options vfio-pci ids=1002:677b,1002:aa98 vga=none Also, yes, after update-initramfs -u I rebooted the host (and with it the guests then), yesterday...

Hi guys, I have a Proxmox host with a Ryzen processor and one GPU, an old AMD card (R5 230 with TeraScale 2). I would like to pass the GPU through to a existing guest with Debian (64 bit), although I am not using the desktop there. I just need the card to be active and having a responsive...

Thank you for your input, care to elaborate a bit?

Hi guys, I have two SSDs running Proxmox and two HDDs connected to it, which are mounted as "hddpool", see below: Now, I am not sure, how to give access to the VMs/guests properly so they can reach the "hddpool" and store files there. As far as I know, if I mount "hddpool" to each VM this...

Oh, sorry, I was so focused on the kernel version, that I did not think about the necessary reboot. Thank you, guys.

Hi guys, I wanted to update my Proxmox host. Unfortunately, apt update && apt upgrade && apt dist-upgrade tells me, everything has the newest state. Is there something wrong with my sources? I read through the repository documentation, aber could not find anything wrong in my sources so...

Nevermind, I had to set it twice (cluster and node, I guess) to get it working.
