It seeems like the firmware didnt load. Try proxmox-boot-tool refresh then reboot.

Kind of running out of options here: Try these: apt install firmware-intel-graphics cat sriov_numvfs Try the latest Kernel 6.17.4-2-pve

cat sriov_totalvfs

Can you list the directory?

note the "" on the command. you will have to include that.

so your command will be echo 2 > "/sys/devices/pci0000:e0/0000:e0:01.1/0000:e1:00.0/0000:e2:01.0/0000:e3:00.0/sriov_numvfs" edit: changed to "2" I forgot you have the latest firmware.

What do you get when you type: find /sys/devices -path "*e3:00.0*sriov_numvfs"?

sriov_numfs is not a directory.. you need to for example want 4 vfs. echo 4 > sriov_numvfs

you will need to install sysfsutils apt install sysfsutils

Did you enable the vfs? If not, one way is to add it to sysfs.conf. example: devices/pci0000:64/0000:64:00.0/0000:65:00.0/0000:66:01.0/0000:67:00.0/sriov_numvfs = 0 devices/pci0000:64/0000:64:00.0/0000:65:00.0/0000:66:01.0/0000:67:00.0/sriov_numvfs = 4 As usual your pci id will differ. As...

I have a Windows 11 VM after a while is showing internal-error in proxmox. The whole VM gets frozen and only way to recover is stop the VM and start it. Tried doing a fresh start and still having the same issue. Only thing that was changed was adding Intel Arc Pro B50 as SR-IOV pass-through...

You are correct, I was just stating one of the functions it can do. I was just wondering if it will help with any hwaccel like VMs with TPM requirements.

I was wondering if having a physical TPM unit gives any benefits installed in host. I know it can be a source for random number generator.

I recommend getting something like "Y" cable with extra usb connector for aux power. Some SSDs/HDD can overwhelm USB port's power, if they are connected to same bus internally.

Yes you do need to add a Qdevice. I am currently rebuilding my homelab and only have two nodes setup so far, and it sometimes causes issues with HA. Run pvecm expected 1 in each of the hosts to get them back and running.

I have a similar issue but everything works as normal on the node that says Status: Unknown on all the Containers and VMs.

Does it always get stuck in the same place (before the spinning circles show up)? Yes. Primarily when the VM is restarting. Rarely from cold start. Can you remember when the issues started and if yes, can you correlate it with a certain update? I had this issue since V6 that I can remember. I...

I have been having issue with this for a while with VMs. Whenever, the VM restarts and it gets stuck on Proxmox EFI boot screen as seen below. Doesn't matter if it is Windows 10 or 11. I haven't tried a linux distro on a vm yet. I have to do a reset for it to boot normally. This happens only...

What motherboard are you using? It looks like that PCI-E group is shared with many other devices. Also, can you post your settings for modules, modprobe, cmdline, etc.

That is great news! I will mark it as solved as soon as comes out to stable.
