 1. open the conf file for the vm found under /etc/pve/qemu-server and delete the line 'template: 1'.

2. Rename the disk using zfs

 I tried these steps: https://homelab-vignettes.blogspot.com/2021/03/migrate-virtualbox-to-proxmox.html

But got this error:

I followed:

When the above happens, boot to rescue mode (choose 2nd option in bootup screen).

And then login using root and run the following command:

dracut --regenerate-all -f

Once done, sync and reboot:

You should change network settings once you have bootup.
