I have a proxmox server that will not boot correctly. It tries to boot normally but hangs with multiple "proxmox boot hangs with libkmod: error: kmod_config_parse: /etc/modprobe.d/vfio.conf " followed by line numbers.

I have tried booting into debug/console mode from the pve installer usb and editing the vfio.conf file and that does not work. I tried deleting the vfio.conf file and updating the initial ram disk using the command "update-initramfs -u" then rebooting. The server tries to reboot again and ends up with the same errors scrolling down the screen and never completes the boot process.

I'd like to avoid starting from scratch with a brand new install on the existing hardware, but I will lose the VMs and LXC containers running on the pve server. I'll probably run into error with the cluster members if I try to use the same hostname and IP address during the fresh install.

Any ideas how I can fix the boot process so it will completely boot successfully?
