This works fine with sdk4. Thanks. Unfortunately I couldn't find away to update cpu_shares config: can't set any update option to update it now or later and no error from the API.
In order to perform the update using version 4 of the SDK you need to do something like this: import static org.ovirt.engine.sdk4.builders.Builders.vm; vmService.update() .vm( vm() .cpuShares(20) ) .send(); This sends the correct request to the server, but as you detected it doesn't have any effect. I believe that is a bug, opened the following BZ to track it: It isn't possible to change the CPU shares of virtual machine when it is up https://bugzilla.redhat.com/1355865

Version 3 of the SDK doesn't support GET parameters, unfortunately. If you are using version 4 of the engine then you may consider using version 4 of the SDK, which does support them:
---8<--- import static org.ovirt.engine.sdk4.ConnectionBuilder.connection;
import org.ovirt.engine.sdk4.Connection; import org.ovirt.engine.sdk4.services.VmService; import org.ovirt.engine.sdk4.services.VmsService; import org.ovirt.engine.sdk4.types.Vm;
// This example will connect to the server and start a virtual machine: public class GetVmNextRun { public static void main(String[] args) throws Exception { // Create the connection to the server: Connection connection = connection() .url("https://engine41.example.com/ovirt-engine/api") .user("admin@internal") .password("...") .trustStoreFile("truststore.jks") .build();
// Get the reference to the "vms" service: VmsService vmsService = connection.systemService().vmsService();
// Find the virtual machine (we need this in order to find // the identifier of the virtual machine given its // name): Vm vm = vmsService.list() .search("name=myvm") .send() .vms() .get(0);
// Locate the service that manages the virtual machine: VmService vmService = vmsService.vmService(vm.id <http://vm.id>());
// Call the "get" method using the "next_run" parameter to // retrieve the configuration of the virtual machine that // will be used the next time it is started: vm = vmService.get() .nextRun(true) .send() .vm();
// Print some details of the virtual machine: System.out.printf("cpu shares: %s", vm.cpuShares());
// Close the connection to the server: connection.close(); } } --->8---
If this isn't an alternative for you, then please open a bug requesting that this support is added to version 3 of the SDK.
