Jclouds пример не работает на хост-машине (devstack)

Question

Я установил Devstack на Virtualbox, и я хочу использовать Jclouds для разработки приложений на моем хосте-машине, когда я проверить пример домашней страницы

import com.google.common.collect.ImmutableSet; 
import com.google.common.io.Closeables; 
import com.google.inject.Module; 
import org.jclouds.ContextBuilder; 
import org.jclouds.logging.slf4j.config.SLF4JLoggingModule; 
import org.jclouds.openstack.nova.v2_0.NovaApi; 
import org.jclouds.openstack.nova.v2_0.domain.Server; 
import org.jclouds.openstack.nova.v2_0.features.ServerApi; 

import java.io.Closeable; 
import java.io.IOException; 
import java.util.Set; 

public class JCloudsNova implements Closeable { 
private final NovaApi novaApi; 
private final Set<String> regions; 

public static void main(String[] args) throws IOException { 
    JCloudsNova jcloudsNova = new JCloudsNova(); 

    try { 
     jcloudsNova.listServers(); 
     jcloudsNova.close(); 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } finally { 
     jcloudsNova.close(); 
    } 
} 

public JCloudsNova() { 
    Iterable<Module> modules = ImmutableSet.<Module>of(new  SLF4JLoggingModule()); 

    String provider = "openstack-nova"; 
    String identity = "demo:demo"; // tenantName:userName 
    String credential = "nova"; 

    novaApi = ContextBuilder.newBuilder(provider) 
      .endpoint("http://127.0.0.0:5000/v2.0/") 
      .credentials(identity, credential) 
      .modules(modules) 
      .buildApi(NovaApi.class); 
    regions = novaApi.getConfiguredRegions(); 
} 

private void listServers() { 
    for (String region : regions) { 
     ServerApi serverApi = novaApi.getServerApi(region); 

     System.out.println("Servers in " + region); 

     for (Server server : serverApi.listInDetail().concat()) { 
      System.out.println(" " + server); 
     } 
    } 
} 

public void close() throws IOException { 
    Closeables.close(novaApi, true); 
} 
} 

я получаю этот выход:

Answer 1

проблема, вероятно, связано с конфигурацией сети в VirtualBox. Ваш первый запрос будет 127.0.0.1:5000, и он правильно обрабатывается службой Openstack Keystone.

Ключевой отклик включает адрес конечной точки службы nova - 10.0.2.15:8774 - в котором должен появиться ваш API-запрос, чтобы перечислить серверы. Возможно, ваш клиент не может подключиться к этому IP-адресу.

Проверьте конфигурацию вашей виртуальной сети - убедитесь, что сетевой режим позволяет операционной системе хоста подключаться к гостевой операционной системе.

Answer 2

Virtualbox не может передавать расширения виртуализации. Вероятно, ваши devstack не могут загружать виртуальные машины под виртуальный бокс.
