Dear Juan / All,
Thanks for reply.
I tried to give the hostname with the tag mentioned "host_name". Its working.
So below are the issues still remaining:
1) The issue of internal server error still persits (rhev manager showing issues) even after following the advice of the expert and doing the initialization part just once(giving ip and hostname) after creating the vm.
Actually this is a bug: https://bugzilla.redhat.com/1144005 The reason is that when you use an incorrect boot protocol we end up storing null in the corresponding place in the database, and later we use the value without checking it, which triggers a null pointer exception. The right value for the boot protocol is "static", not "STATIC_IP". The "STATIC_IP" value is what we use in the backend and in the database, but in the RESTAPI it is "static". To workaround this issue you can delete the VMs and create them again with the correct boot protocol. If you don't want to create the VMs again you can fix the database manually like this: # su - postgres # psql postgres=# \c engine engine=# update vm_init set networks = replace(networks, '"bootProtocol" : null', '"bootProtocol" : "STATIC_IP"');
2) Please confirm if this is the case that we can do initialization part only once on a particular vm , then we can reconfigure the network (ip, subnet, gateway etc) or not for that vm.
I'm reasonably sure that you can run initialization only once per VM, but Shahar can confirm this better than me.
3) For Windows guest we are still unable to provide ip details and hostname using sysprep/payload.
I'm not familiar with Sysprep. Can you provide an example of the code that you are using for that?
Error attached.

Dear Experts.
We are Integrating our internal cloud portal with Ovirt / RHEVM version 3.4.
We are integrating our internal cloud with Ovirt / RHEVM. VM template created using cloud init.
Through REST API Nippet while codes passes command to template ( with cloud init) IP, HOSTNAME, We are able to set IP and Hostname to VM through code.
But post this Manager getting handed. Error code is attached.
Need your help please.
If I understand correctly you already created a template with the cloud init configuration, then you created a VM from that template, and you want to modify it and start it. In order to update the VM you need to issue a PUT request, and the tag name for the host is "host_name":
String updateXml = "<?xml version=\"1.0\"?>" + "<vm>" + "<initialization>" + "<host_name>meghaasadmin.ultimatixuat.net</host_name>" + "<regenerate_ssh_keys>false</regenerate_ssh_keys>" + "<nic_configurations>" + "<nic_configuration>" + "<name>eth0</name>" + "<ip address=\"1.1.1.1\" netmask=\"255.255.255.0\" gateway=\"13.3.3.3\"/>" + "<boot_protocol>static</boot_protocol>" + "<on_boot>true</on_boot>" + "</nic_configuration>" + "</nic_configurations>" + "</initialization>" + "</vm>"; StringEntity updateEntity = new StringEntity(updateXml); HttpPut updateRequest = new HttpPut(apiUrl + "/vms/" + vmId); updateRequest.setHeader("Content-Type", "application/xml"); updateRequest.setHeader("Accept", "application/xml"); updateRequest.setEntity(updateEntity); HttpResponse updateResponse = client.execute(updateRequest);
Then, after the update, you need to start the VM and it will use that configuration:
String startXml = "<?xml version=\"1.0\"?>" + "<action/>"; StringEntity startEntity = new StringEntity(startXml); HttpPost startRequest = new HttpPost(apiUrl + "/vms/" + vmId + "/start"); startRequest.setEntity(startEntity); startRequest.setHeader("Content-Type", "application/xml"); startRequest.setHeader("Accept", "application/xml"); HttpResponse startResponse = client.execute(startRequest);
Some advices:
* Check the XML schema for the structure of the XML documents:
https://rhevmanager/api?schema
* When sending requests to the RESTAPI makes sure to always explicitly add the Content-Type and Accept headers:
yourRequest.setHeader("Content-Type", "application/xml"); yourRequest.setHeader("Accept", "application/xml");
* Take into account that the initialization with cloud-init will only be executed the first time you start the VM, so in your tests you will need to remove the VM and create it again.
* If you are planning to do complex things you may find it helpful the Java SDK:
