[libvirt-users] java binding and virtualbox-ose

[Andrea Turli]

I'm trying to connect to vbox hypervisor on an Ubuntu 10.04 machine
through libvirt java binding (libvirt-java-0.4.6) by simply invoking:

Connect conn = new Connect("vbox:///session", false);
but I got this exception:

libvir: warning : Failed to find the interface: Is the daemon running ?
libvir: Remote error : unable to connect to
'/var/run/libvirt/libvirt-sock': Connection refused
libvir: warning : Failed to find a node driver: Is the libvirtd daemon running ?
libvir: Remote error : unable to connect to
'/var/run/libvirt/libvirt-sock': Connection refused
libvir: warning : Failed to find a secret storage driver: Is the
daemon running ?
org.libvirt.LibvirtException: Failed to find a secret storage driver:

   at org.libvirt.ErrorHandler.processError(ErrorHandler.java:28)
   at org.libvirt.Connect.<init>(Connect.java:195)
   at VBOX.main(VBOX.java:32)
Otherwise, from virsh, I can correctly connect to the vbox hypervisor:

Do you have any hint? Thank you
