HELP !

I was just messing with a VM and PCI passthrough'd the only ethernet port on my tiny Lenovo box to a VM - I know ...
Now I can no longer get back in, the box boots up with the normal login message ip:8006 but that disappears after a few seconds and no video out. The offended VM is numbered 1101. How can I delete/disable that VM ? the only way I can think of is a tiny linux distro on a USB to login and delete it ! -I have no idea how to do that?

I'm not sure how, but things are now working again. I did a ctrl X to no avail, I also pressed E and C I think in the grub screen and after a couple of reboots it came back - phew !

Please can Proxmox have a self backup option !

You could also enter die BIOS/UEFI and disable IOMMU. With that PCI passthrough and starting all VMs using that will fail.

Thanks both, I was going down the road off RS232 console, I have a USB to RS232 and the Lenovo has 9pin RS232, I don't think Proxmox has it enabled by default, I couldn't find the gender changers I have somewhere and a crossover cable. I did download puppylinux.iso for Ventoy
