Hello, I am trying to use the libvirt Java bindings (version 0.4.7) with libvirt version 0.9.12 to connect to a XenServer hypervisor. Virsh is able to connect to my XenServer, but when I try to do the same thing in Java, it won't connect. Here is the debug output: 2012-06-26 19:48:52.259+0000: 26051: info : libvirt version: 0.9.12, package: 1.fc16 (Unknown, 2012-06-26-11:43:53, flynx) 2012-06-26 19:48:52.259+0000: 26051: warning : virLogParseOutputs:993 : Ignoring invalid log output setting.

connect: Cannot read CA certificate '/etc/pki/CA/cacert.pem': No such file or directory Even though the output mentions not finding a CA certificate, that's not the problem. I have a custom ConnectAuth class so the user can give the password before trying to connect and isn't prompted for it. The problem occurs when trying to create the Connect Object. -- Thanks, Nick Mathews
