30 Router 10.4.1.x (192.168.1.254) running
I'm using a compiled version of libvirt that I enabled the xenapi protocol.
[jdrews@flynx ~]$ virsh -v
0.9.10
I can also start and stop VMs via virsh.
So the next move for me was to get this working with the java bindings, libvirt-java. I grabbed libvirt-0.4.7.jar and built it. Eclipse is set up and I can see everything correctly. I built a small runnable test jar and ran it.

But I know there is a route to the host as virsh could get there. Sanity check: ping works fine too.
[jdrews@flynx ~]$ ping 192.168.1.23

Here is the code I'm running in the VirtAPITesting.jar. For the most part it's a direct copy of the example at the end of the libvirt java page: http://libvirt.org/java.html
package com.jdrews.VirtAPI.testing;
import org.libvirt.*;
public class VirtAPITesting {
public static void main(String[] args) throws InterruptedException {
System.setProperty("jna.library.path", "/usr/local/lib/");

System.out.println(
ConnectAuth defaultAuth = new ConnectAuthDefault();
try{
conn = new Connect("xenapi://root@192.168.1.23?no_verify=1", defaultAuth, 0);
} catch (LibvirtException e){
System.out.println("exception caught:"+e);
System.out.println(e.getError());
}
try {
Domain testDomain=conn.domainLookupByName("DeviceSimulator (192.168.1.150)");
System.out.println("Domain:" + testDomain.getName() + " id " +
testDomain.getID() + " running " +
testDomain.getOSType());
} catch (LibvirtException e) {
System.out.println("exception caught:"+e);
System.out.println(e.getError());
}
}
}
Does anyone know what's going on here? Any help or advice would be greatly appreciated. Thanks!
