Hello,

Two ways of thinking:

1. the vdsm hook could be very easy to write so as to make what you desire (ovirtsdk4 is presinstalled on ovirt node):
   
   import ovirtsdk4 as sdk

   import ovirtsdk4.types as types

   from vdsm.hook import hooking

   # Get the vm name from xml definition:

   domxml = hooking.read_domxml()

   vm_name = domxml.getElementsByTagName('name')[0].firstChild.nodeValue

   print(vm_name)

   connection = sdk.Connection(

   url='https://engine.example.com/ovirt-engine/api',

   username='admin@internal',

   password='password',

   ca_file='ca.pem',

   )

   # Find the virtual machine:

   vms_service = connection.system_service().vms_service()

   vm = vms_service.list(search = vm_name)[0]

   # Find the service that manages the virtual machine:

   vm_service = vms_service.vm_service(vm.id)

   # Start the virtual machine enabling cloud-init and providing the

   # password for the `root` user and the hostname:

   vm_service.start(

   use_cloud_init=True,

   vm=types.Vm(

   initialization=types.Initialization(

   user_name='root',

   root_password='password',

   host_name= vm_name + 'example.com'

   )

   )

   )

   # Close the connection to the server:

   connection.close()
   Then place it as executable in /usr/libexec/vdsm/hooks/before_vm_start on each host that should be able to run the pool vms.
   
   
2. As the web UI already auto fills the VM hostname cloud-init field with the vm name (or fqdn), the VM Hostname should do the same with vm pool, but it doesn't. You could open a RFE for this, it shouldn't be very complicated to patch it.
   

I thought that:- you know the name of the future VM

I will try to clarify: I'm trying to obtain from the oVirt engine the name of the VM created inside the pool.
For example if the VM in pool LinuxPool is called LinuxMachine-1 I want the cloud-init to know that the VM is called LinuxMachine-1 and with this info add the suffix using the method you described.
Again, thank you a lot for the response.
