Libvirt has to spawn an external SSH process for +ssh URIs, so we can't hook
it up into our auth callbacks.

You need to setup SSH public keys + SSH agent

virConnectOpenAuth() doesn't do anything useful for '+ssh' URIs.
There is however a alternative 'libssh2' URI that does use the
callbacks. eg qemu+libssh2://hostname/system
This is less tested & potentially buggy, but it might be ok for your needs
