virt-manager启动时提示no d-bus daemon running

bgsmgrx

在opensuse13.1上安装了kvm libvirt virt-manager这几个包，重启完，启动完libvirtd服务后，打开virt-manager时提示no d-bus daemon running

Error starting Virtual Machine Manager: No D-BUS daemon running

Traceback (most recent call last):

    self.conf.add_dir(self.conf_dir, gconf.CLIENT_PRELOAD_NONE)
GError: No D-BUS daemon running

但是dbus服务是启动了的，这是什么问题呢？
