我正在尝试通过 libvirt java 绑定通过简单地调用来连接到 Ubuntu 10.04 机器上的 vbox 管理程序：
Connect conn = new Connect("vbox:///session", false);
但我得到了这个例外：
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 ?

at org.libvirt.ErrorHandler.processError(ErrorHandler.java:28)
at org.libvirt.Connect.<init>(Connect.java:195)
at VBOX.main(VBOX.java:32)
否则，从 virsh，我可以正确连接到 vbox 管理程序：
$ export LIBVIRT_DEBUG=1
