Warning: UPDATING these packages broke my pci passthrough.

[AWP Technologies]

I installed updates

libpve-common-perl/stable 8.2.6 all [upgradable from: 8.2.5]
pve-firmware/stable,stable 3.14-1 all [upgradable from: 3.13-3]
qemu-server/stable 8.2.5 amd64 [upgradable from: 8.2.4]

After doing this i was getting a task error saying cannot bind <pci-device> to vfio

Because my router is a vm with a pass through network card it screwed me. I had to bring out backup router and down grade all of these packages and then pass through was immediately restored.

I just wanted to post this to warn everyone and also let the devs know there is an issue with these packages.

I am on kernel Linux 6.8.12-3-pve
pve manager version: pve-manager/8.2.8

I forgot to mention that i don't know exactly which package fixed my issue. I updated all three
libpve-common-perl to 8.2.6
pve-firmware to 3.14-1
qemu-server to 8.2.5

Immediately after reboot vm wouldn't start because of the pci bind issue.

I then went down the list 1 by 1 downgrading and restarting host. It didn't start working again until i downgraded all three.

could you try downgrading the 'libpve-common-perl' package to see if that would fix it?

you can do that with

apt install libpve-common-perl=8.2.5

EDIT: sorry i missed that you already downgraded...
did you try just the libpve-common-perl too?

Thank you very much sharing your experiences. This is exactly what happened to me.
All my vm's with pcie passthrough went down after the update. Finally, I have a clue regarding to what to do.

Could you please share your steps how you downgraded them? Thank you.

Downgrading libpve-common-perl gave me errors therefore, I downgraded it last after rebooting my server with the other two downgrades. At that time, my pcie passthrough still was not working. After finally downgrading libpve-common-perl, everthing works. Thank you for the original poster for the info.

The same thing happened to me.
I downgraded libpve-common-perl to 8.2.5 and qemu-server to 8.2.4.
And now my OpenWRT virtual machine with PCI passthrough can be started again.
