1) How are you ending up with an LVM partition? You must be using a
different "storage:" section.

2) I ran "fdisk -l" in the VM that I'd created, and it wasn't what I'd
requested in the autoinstall file. It seems that you can use

  storage:
    layout:

or

  storage:
    config:

and I used both in my user-data. "layout:" that won the day, and all
that I had was a biosboot partition and a root partition.

This did the right thing:

  storage:
    config:
      - id: disk0
        type: disk
        match:
          size: largest
        ptable: gpt
        grub_device: true
        wipe: superblock
      - id: disk0-biosboot
        type: partition
        flag: bios_grub
        device: disk0
        size: 1MB
      - id: disk0-boot
        type: partition
        device: disk0
        size: 512MB
      - id: disk0-root
        type: partition
        device: disk0
        size: -1
      - id: disk0-boot-fs
        type: format
        volume: disk0-boot
        fstype: ext4
      - id: disk0-root-fs
        type: format
        volume: disk0-root
        fstype: ext4
      - id: disk0-boot-mount
        type: mount
        device: disk0-boot-fs
        path: "/boot"
      - id: disk0-root-mount
        type: mount
        device: disk0-root-fs
        path: "/"
