NIC PCI device not attached to device

[erahall]

I attached PCI (NIC) devices to a VM and then deleted that VM. Now the PCI devices are not attached to a network interface anymore.

lshw -class network -businfo
pci@0000:04:00.0  enp4s0          network        RTL8125 2.5GbE Controller
pci@0000:05:00.0  enp5s0          network        I211 Gigabit Network Connection

Restarting proxmox reattach those properly. Is there a way to reattach those devices without restarting proxmox ?

Unbind vfio-pci and bind the actual driver for the device(s) again. See for example threads like this one: https://forum.proxmox.com/threads/gpu-pci-e-passthrough-output-question.155489/post-709062 or this one: https://forum.proxmox.com/threads/back-passthrough-gpu-to-proxmox.152203/post-689977
