Hi,
I'm developping (in JAVA) an automatic configuration manager to modify
memory and cpu allocation (cpushares for the moment) updated on a
calendar basis. It will also be used as a kind of enforcer/elastic
scheduler on top of the ovirt policy scheduler.
Because oVirt is not yet able to update memory and cpushares on live
guests like XenServer, my configurator needs to know the running config
and the next_run config as well, and force directly the config on live
guests (with virsh schedinfo --live arg ? ).
Unfortunately, the Host.getVMs().getById( "uuid" ) method returns only
the running config so there's no way I can check if the future config is
setup.
Any suggestion?
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());
// 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();
}
}

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.
