Dear oVIrt,

Even though I would like to get some insight into what could be reason this is 
no working, I did find a workaround:

Instead of trying to get Ubuntu disk specified with ovirt_disk size,
I used qemu-img resize to increase the disk size before importing it to oVIrt.
This works, but it still going to present the problem if User eventually wants 
to increase for example disk from 40GBto 80GB.

Kindly awaiting your reply.

Subject: ovirt_disk and ubuntu issues

Dear oVirt,

I am downloading the ubuntu cloud image 16.04 and or 18.04:

   - name: "Download base cloud image from server"
     get_url:
       url: "{{ image_url }}"
       checksum: "sha256:{{ image_checksum }}"
       validate_certs: yes
       dest: "/tmp/{{ inventory_hostname_short }}.qcow2"
     delegate_to: localhost

creating a 40GB HDD and attaching image to it:

    - name: "Create oVirt disk with base image (with 40Gb allocated)"
      ovirt_disk:
        name: "{{ inventory_hostname_short }}"
        interface: virtio
        size: 40GiB
        format: cow
        upload_image_path: "/tmp/{{ inventory_hostname_short }}.qcow2"
        storage_domain: ovirt_production
        wait: true
      delegate_to: localhost

creating VM afterwards:


    - name: "Create new Ubuntu VMs from cloud image"
      delegate_to: localhost
      ovirt_vm:
        auth: "{{ ovirt_auth }}"
        name: "{{ inventory_hostname_short }}"
        disks:
        - name: "{{ inventory_hostname_short }}"
        graphical_console:
            protocol: vnc
        serial_console: true
        usb_support: true
        soundcard_enabled: false
        operating_system: "{{ operating_system_type }}"
        type: server
        nics:
        - name: nic1
          profile_name: tenant1
          interface: virtio
          nic_on_boot: true
        cloud_init:
          host_name: "{{ inventory_hostname }}"
          user_name: ubuntu
          authorized_ssh_keys: "{{ ssh_agent_pubkeys.stdout }}"
        state: "running"
        cluster: "{{ ovirt_cluster }}"
      when: inventory_hostname in groups['ubuntu-baker']

When VM gets created, I can see in oVIrt VM details disk created is 40GB.
Executing df -h, gives me following:

  root@av3-ubuntu-18-base:/home/ubuntu# df -h
Filesystem      Size  Used Avail Use% Mounted on
udev            447M     0  447M   0% /dev
tmpfs            92M  696K   92M   1% /run
/dev/vda1       2.0G  1.3G  706M  65% /
tmpfs           460M     0  460M   0% /dev/shm
tmpfs           5.0M     0  5.0M   0% /run/lock
tmpfs           460M     0  460M   0% /sys/fs/cgroup
/dev/vda15      105M  3.6M  101M   4% /boot/efi
tmpfs            92M     0   92M   0% /run/user/1000

Initially I thought growpart or resize2fs is not triggered, but then running 
dmesg or fdisk /dev/vda, told me that physical disk size is still only size of 
the downloaded ubuntu cloud image.

Disk /dev/vda: 2.2 GiB, 2361393152 bytes, 4612096 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

Is this related to ovirt_disk module, or ubuntu and ovirt_disk, since I do not 
have this behavior with CentOS 7 images?

Can you advise how to proceed, in case I am missing some configuration 
parameter or command to be run?

The following Ubuntu images are used:

ubuntu-16: 
image_url=https://cloud-images.ubuntu.com/xenial/current/xenial-server-cloudimg-amd64-disk1.img
 image_checksum=fda868058586b129c7fdb6472fe575e911f7c67551a6dc75966f2ec02201bdae
ubuntu-18: 
image_url=https://cloud-images.ubuntu.com/bionic/current/bionic-server-cloudimg-amd64.img
 image_checksum=7d2b90022a169119d7726c0fefa1713acbead7cc36d282c879896fd89c5a6663


Kindly awaiting your reply.
