Hello, this is my example:

export DIB_BLOCK_DEVICE_CONFIG=$(cat mylvm_centos8_nmsf.yaml)


this is my mylvm_centos8_nmsf.yaml:
- local_loop:
    name: image0
    size: 30G

- partitioning:
    base: image0
    label: mbr
    partitions:
      - name: root
        flags: [ boot,primary ]
        size: 100%

- lvm:
    name: lvm
    base: [root]
    pvs:
      - name: pv
        base: root

    vgs:
      - name: vg_rootcentos8
        base: ["pv"]

    lvs:
      - name: lv_root
        base: vg_rootcentos8
        size: 5000M

      - name: lv_var
        base: vg_rootcentos8
        size: 5000M

      - name: lv_usr
        base: vg_rootcentos8
        size: 5000M

      - name: lv_swap
        base: vg_rootcentos8
        size: 2000M

      - name: lv_tmp
        base: vg_rootcentos8
        size: 1500M

      - name: lv_appserv
        base: vg_rootcentos8
        size: 8000M


- mkfs:
    name: mkfs_root
    base: lv_root
    label: "img-rootfs"
    type: "ext4"
    mount:
      mount_point: /
      fstab:
          options: "noacl,errors=remount-ro"
          fsck-passno: 1

- mkfs:
    name: mkfs_var
    base: lv_var
    type: "ext4"
    mount:
      mount_point: /var
      fstab:
          options: "noacl"
          fsck-passno: 2

- mkfs:
    name: mkfs_usr
    base: lv_usr
    type: "ext4"
    mount:
      mount_point: /usr
      fstab:
          options: "noacl"
          fsck-passno: 2

- mkfs:
    name: mkfs_swap
    base: lv_swap
    type: "ext3"
    mount:
      mount_point: swap
      fstab:
          name: swap
          options: "swap"

- mkfs:
    name: mkfs_tmp
    base: lv_tmp
    type: "ext4"
    mount:
      mount_point: /tmp
      fstab:
          options: "noacl"
          fsck-passno: 2

- mkfs:
    name: mkfs_appserv
    base: lv_appserv
    type: "ext4"
    mount:
      mount_point: /appserv
      fstab:
          options: "noacl"
          fsck-passno: 2




After creating the image I modified it as follows:

guestfish -a /tmp/centos8_nmsf_ansible_heat.qcow2 -i mkswap-L  mkfs_swap
/dev/vg_rootcentos8/lv_swap
