cat <<'NOTE'
NOTE:
- If a VMID uses rootfs "local-lvm:*" on a node where storage.cfg restricts "local-lvm" to other nodes,
  the container may fail to start after a shutdown/reboot.
- Fix is to update /etc/pve/storage.cfg nodes=... for that storage to include the node hosting the VMID,
  or migrate the VMID to an allowed node/storage.
NOTE
