I've created a 8Gb disksize ProxMox VM template. Using ansible module proxmo_kvm I clone it but I can't resize the SCSI disk. Is it possible to do ? if it is could you give me some explanations to understand how ?

Running Ansible playbook:

ansible-playbook playbook.yml

I'm expecting a new 16Gb disksize VM, but the actual disksize is 8Gb (initial disksize template)

Currently it is not possible because ansible module proxmox_kvm does't allow it (neither for clone nor for update). See the source code of the module (proxmox_kvm.py):

# [...]
def create_vm(module, proxmox, vmid, newid, node, name, memory, cpu, cores, sockets, timeout, update, **kwargs):
# [...]
 # valide clone parameters
 valid_clone_params = ['format', 'full', 'pool', 'snapname', 'storage', 'target']
# [...]
 elif module.params['clone'] is not None:
 for param in valid_clone_params:
 if module.params[param] is not None:
 clone_params[param] = module.params[param]
 clone_params.update(dict([k, int(v)] for k, v in clone_params.items() if isinstance(v, bool)))
taskid = proxmox_node.qemu(vmid).clone.post(newid=newid, name=name, **clone_params)
# [...]
 # If update, don't update disk (virtio, ide, sata, scsi) and network interface
 if update:
# [...]
 if 'scsi' in kwargs:
 del kwargs['scsi']
# [...]

It's possible with ansible module uri. Add following tasks to the file proxmox-vm/tasks/main.yml:

# get VMID
- name: get VM state
 proxmox_kvm:
 api_host: " proxmox.api.host "
 api_user: " proxmox.api.user "
 api_password: " proxmox.api.password "
 node: " proxmox.node"
 name: " proxmox.vm.name "
 state: current
 register: result
- name: set fact VMID
 set_fact:
 vmid: " regex_replace('.*vmid = ([1-9][0-9]0,3).*', '\1') "
