crashes after boot while VMs start

[Tornavida]

Hi, I have a little big problem.
While making some configs over the WebGUI I deleted a drive of a VM and pressed a key before waiting for the system's confirmation.
So, the system started to fail after that and i decided to reboot the server in hope that it will reinitialize all.
Well - It didn't ...
now my system starts to boot and the VMs that are set to run straight after the system start, start to boot too and before I'm able to get into the webGUI the system crashes.
I need to get onto my system before the VMs start so I can disable that one VM that causes troubles. but I got no clue how.
Help would be greatly appreciated

I have tried with a live rescue usb. Well there I couldn't mount the pve to get to the configs ...

Hello,


Have you tried to disable the start VM at boot with CLI e.g?

pvesh create /nodes/<Node Name>/qemu/<VMID>/config --onboot 0

Another option is to edit the kernel parameters (press 'e' in the GRUB of systemd boot menu) when starting the system and remove the intel_iommu or amd_iommu option. This will almost always prevent all your VMs from starting, which will allows you the change the files in /etc/pve/qemu-server. Then just reboot and you can start VMs again (the change to the kernel parameters is not presistent).
