Locked out from server PVE

[pindaroli]

Hi all and happy new year. I changed badly /etc/network/interface file and now i cannot access to ip of PVE.
I tried to open a terminale directly attached to node hosting but i cannot open any terminal for recovery.
Help me please!

When you say "terminale" - I guess you mean a physically HW attached monitor to the host. What do you see on it? Do you have any GPU-passthrough going on to a VM? If you hard reboot the node what do you see on the monitor?

Are any VMs/LXCs alive on your NW?
Are any of them pingable?
Is the host pingable?

Yes I am physically attached monitor keybord and mouse, nogpu pass-through. I saw the log scrolling, i tried a lot of key combinations but no prompt opened to recover. The host is not pingable because I badly changed interface name after adding a new x520 10g nics

You will have to boot from Proxmox USB into recovery mode, then you will have to mount the rootfs of your (current non-working) PVE & make the changes to get it working again.

See here for an example.
