I installed Devstack on Virtualbox and I want to use Jclouds for application development on my host machine, when I test the homepage example
import com.google.common.collect.ImmutableSet;

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);
}
}
I get this output :

Notes that I use intelijIdea for an IDE
The problem is probably related to the network configuration of the virtualbox. Your first request is going to 127.0.0.1:5000, and is handled correctly by the Openstack Keystone service.
The keystone response includes the address of the nova service endpoint - 10.0.2.15:8774 - which is where your API call to list the servers should go. Your client seems to be unable to connect to this IP.
Check your virtualbox network configuration - make sure that the network mode allows the host operating system to connect to the guest operating system.
