How to set the size of root disk vm when using container root fs

[sharadregoti]

This is my virtlink yaml. Even though I have set the size as 10Gi it does not have any effect.

apiVersion: virt.virtink.smartx.com/v1alpha1
kind: VirtualMachine
metadata:
  labels:
    virtlink.io/os: linux
    virtlink.io/vm: "{{ .Values.virtualMachine.name }}"
  name: "{{ .Values.virtualMachine.name }}"
spec:
  instance:
    # TODO: Set up cpu
    # https://github.com/smartxworks/virtink/blob/main/docs/dedicated_cpu_placement.md
    memory:
      size: "{{ .Values.memory }}"
    interfaces:
      - name: pod
    disks:
      - name: image
      - name: cloud-init
  volumes:
    - name: image
      containerRootfs:
        image: "{{ .Values.image }}"
        size: 10Gi
    - name: cloud-init
      cloudInit:
        userData: |-
          #cloud-config
          system_info:
            default_user:
              name: ubuntu
              home: /home/ubuntu

          password: ubuntu
          chpasswd: { expire: False }
          hostname: ubuntu

          runcmd:
            - chown ubuntu:ubuntu /home/ubuntu -R

          # configure sshd to allow users logging in using password
          # rather than just keys
          ssh_pwauth: True
          ssh_authorized_keys:
            - {{ .Values.virtualMachine.sshKey }}
  networks:
    - name: pod
      pod: {}

I am running a ubuntu cloud disk image. (The default size that I get is 2GB)

ubuntu@ubuntu:~$ df -h

/dev/root 2.0G 1.9G 85M 96% /

It should work. See code here.
