[libvirt-users] Python Libvirt Bindings

Hi, Can anyone please share sample Python code for using qemu+tcp with SASL or qemu+tls with SASL? (i.e., connecting to a hypervisor using qemu+tls or qemu+tcp when a username/password using SASL has been defined on the hypervisor) I am having some trouble figuring out how to use callbacks for authenticating from with my Python program. I assume I will have to use http://libvirt.org/html/libvirt-libvirt.html#virConnectCredentialType, but I can't quite translate that to Python from C. Thanks
