8.2 has totally borked my Proxmox. GRUB timeout is 0 and I can't stop VM autostart

[ilium007]

I think my PVE issue is due to PCI passthru and I'd like to start up PVE to edit the cons file to stop the autostart so I can reconfigure. I (stupidly) had the GRUB timeout set to 0 and can't enter any sort of rescue mode to edit. I have tried booting with rescue USB but can't access any config files (found out its all stored in a DB).

It gets better.... my backups are on OpenMediaVault which was running as a VM on PVE. I haven't yet tried mounting the BTRFS mirror on those passthru drives to access the backups.

What a mess.

I mounted the OMV btrfs mirror with systemrescue and copied all the proxmox backups to an external USB drive. Looks like I am safe.

I did have all the backups in restic offsite, just glad I didn't have to restore from there.

I figure putting back up on top of the thing that's being backed up, is not a good idea.

You would be correct, that's why I run the offsite restic backup.

Maybe just disable IOMMU in the motherboard BIOS so the autostart of the VM fails early?

Good idea but I've already rebuilt PVE and up and running again, sort of. This new version is causing a lot of weird issues for me. Previous install ran for over a year with no issue. I just had to go and upgrade it.....
