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):
importovirtsdk4 assdk
importovirtsdk4.types astypes
fromvdsm.hook importhooking
# 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.
