You need to specify the server in this URI using a hostname or IP
address: qemu+tcp://ubuntu-server.com/system

You also need to change this

   #auth_tcp = "sasl"

to

   auth_tcp = "none"

to disable SASL authentication/encryption for TCP connections, because
your libvirt on Windows is compiled without SASL support. If you need
the libvirt connections to be encrypted you can switch from TCP to TLS
connections using: qemu+tls://ubuntu-server.com/system

For Ubuntu packaged libvirt see /etc/default/libvirt-bin and change

   libvirtd_opts="-d"

to

   libvirtd_opts="-d -l"

as the comment suggest and restart libvirtd using

   /etc/init.d/libvirt-bin restart

Now you should be able to connect to the libvirtd on your Ubuntu server.
