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-cl...
image_checksum=fda868058586b129c7fdb6472fe575e911f7c67551a6dc75966f2ec02201bdae
ubuntu-18:
image_url=https://cloud-images.ubuntu.com/bionic/current/bionic-server-cl...
image_checksum=7d2b90022a169119d7726c0fefa1713acbead7cc36d282c879896fd89c5a6663
Kindly awaiting your reply.
