I tried below:
$ qemu-img resize -f raw --shrink $(pvesm path <lvm-thin-storage>:<vm-disk>) -1G
qemu-img: Cannot resize device files
How can I shrink it?
I tried cloud-init with ubuntu-18.04-minimal-cloudimg-amd64.img from official link, ubuntu-18.04-server-cloudimg-amd64.img from this link and bionic-server-cloudimg-amd64.img from this link. They were all failed to boot with "No bootable disk" messages alike. I had followed Cloud-Init_Support...
