Vm does not boot up after removing single Gpu from cluster

[mert98]

Hello;
I am new on proxmox
I have a cluster running with Proxmox version 7.1-7, Cluster has a Nvidia-RTX3060 and Nvidia-RTX3090 GPU. I have Passthrough both GPU without any problems, and have been working with ubuntu vm's using both separate GPU however recently I had to remove RTX3090 gpu from cluster due to a technical issue. After removing GPU, Proxmox boot up without any problem also I can start up my other ubuntu vm's (Running with cpu only). However I cannot boot up my VM running with RTX3060 Gpu. When I remove 3060 GPU from VM's hardware VM boots up without any problem. I don't understand what causes this problem, I thought may be Pci passthrough broken after removing 3090 GPU from cluster but I am not sure.

When a component isn't available the VM won't start. You should by the way always remove all PCI passthroughs before removing or adding a PCI card because and remove autostart from those VMs because otherwise you might passthrough a wrong IOMMU group and crash the whole node or even get into a reboot loop.

hi,

can you post the task log and the output of 'dmesg' when the vm start does not work?
also the vm config would be interesting.
