Hi Experts,

We are integrating RHEV(M) with our internal cloud portal using RHEV(M) API, we are able to provision Linux VM using API. But IP and Hostname not getting reflected on vm first boot. If we boot VM manually using run once its working fine. We are not able to find any run once API on RHEV end.

Requested your help on this.

Assuming that you already installed cloud-init in the VM and that you want to specify the cloud-init parameters as part of the request to start the VM, then you will need something like this: ---8<--- !/bin/sh -ex url="https://engine.example.com/ovirt-engine/api" user="admin@internal" password="..." curl \ --insecure \ --user "${user}:${password}" \ --request POST \ --header "Content-Type: application/xml" \ --header "Accept: application/xml" \ --data ' <action> <vm> <initialization> <cloud_init> <host> <address>myhost.example.com</address> </host> <network_configuration> <nics> <nic> <name>eth0</name> <network> <ip netmask="255.255.255.0" gateway="10.10.10.1" address="10.10.10.1"/> </network> <boot_protocol>static</boot_protocol> <on_boot>true</on_boot> </nic> </nics> </network_configuration> </cloud_init> </initialization> </vm> </action> ' \ "${url}/vms/0f3c320-a409-4e9f-918e-3172818d54ed/start --->8--- If you prefer the Python SDK (which is much better the moment you want to do something more complicated) then it should be something like this: ---8<--- #!/usr/bin/python from ovirtsdk import api from ovirtsdk.xml import params api = api.API( url="https://engine.example.com/ovirt-engine/api", username="admin@internal", password="...", insecure=True ) vm = api.vms.get(name="myvm") action = params.Action( vm=params.VM( initialization=params.Initialization( cloud_init=params.CloudInit( host=params.Host( address="myhost.example.com" ), network_configuration=params.NetworkConfiguration( nics=params.Nics( nic=[ params.NIC( name="eth0", boot_protocol="static", on_boot=True, network=params.Network( ip=params.IP( address="10.10.10.1", netmask="255.255.255.0", gateway="10.10.10.1" ) ) ) ] ) ) ) ) ) ) vm.start(action) api.disconnect() --->8--- You can also use the Java SDK, let me know if you need an example of that.
