Dear Juan, Thanks lot for support.
Internal server error issue also resolved with linux guests. Now we are able to provide ip and hostname to linux guests in rhev 3.4 successfully via RESTAPI giving boot protocol as "static" as advised. For Windows Guest we did the following: 1) Prepared a template with guest agents installed and deployed a vm successfully through RESTAPI. 2) Following initialization part same as Linux guest did not work in this case and it gives default/garbage ip,hostname to the vm. 3) So we tried giving it through sysprep/payload tag through REST API. Code snippet is as follows: HttpPut put = new HttpPut( " https://rhevmanager/api/vms/7dac74d2-c504-4bbd-8659-c8773a844cb3/"); String inputXML1 = "<?xml version=\"1.0\"?>" /*"<vm>"*/ +"<sso>"+"<methods>"+"<method id=\""+"GUEST_AGENT"+"\"/>"+"</methods>"+"</sso>" +"<domain>"+"<name>ultimatixuat.net</name>"+"</domain>" +"<payloads>"+"<payload type=\""+"floppy"+"\">"+ "<files>"+"<file>" +"<name>/WEB-INF/sysprep.xml</name>" +"</file>"+"</files>"+"</payload>"+"</payloads>" +"<reported_devices>"+"<reported_device>"+"<ips>"+"<ip address=\""+"1.1.1.1"+"\"/</ips>" +"<fqdn>WIN-AS05EOADAwerwer</fqdn>"+"</reported_device>"+"<reported_devices>"; StringEntity input1 = new StringEntity(inputXML1); put.setEntity(input1); put.setHeader("Content-Type", "application/xml"); HttpResponse responseNIC = httpclient.execute(put); System.out .println("RESPONSE ::::::::::::::::::::::::::::::::::: " + responseNIC); BufferedReader rd1 = new BufferedReader(new InputStreamReader( responseNIC.getEntity().getContent())); String line1 = ""; while ((line1 = rd1.readLine()) != null) { System.out.println("LINE ::::::::::::: " + line1); } The output says that my code is syntactically incorrect. I am not very sure as to what has to be the content of "sysprep.xml" file and what is syntactically incorrect here. Also while deploying the windows machine manually through the rhev manager , while using sysprep option in "run once" , I am unable to find the ip and hostname options as found for linux machines.

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.
