I guess if you manage to script it (modification of the cloud init script), then you can use 'before_vm_start' to trigger your script.

I would like set as hostname the name of the VM + a static suffix appended at the end of the name (EXAMPLE: <VM name>.static.suffix ), is there a way to pass to cloud-init the name of the VM and do this via cloud-init? I've tried to look for something in oVirt and cloud-init documentation and found nothing. Thanks a lot to everybody for the help and have a nice day. _______________________________________________ Users mailing list -- users(a)ovirt.org To unsubscribe send an email to users-leave(a)ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/K6S6E3AOVQY...

with before_vm_start you should be able to modify the cloudinit configuration. I guess there is a misunderstanding. I thought that:- you know the name of the future VM- you want to change the hostname via cloudinit Best Regards,Strahil Nikolov On Fri, Jan 14, 2022 at 10:45, Luca Contessa&lt;ifdevurandom(a)gmail.com&gt; wrote: Hi, sorry for the late response, can you expand a bit more on what you said? in particular, if I understood correctly, you are suggesting I should launch a script to modify the name using oVirt's 'before_vm_start' hook? And also in which way can i get the VM name using this method?

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.
