What's wrong with my Xen bridge configuration

I'm on Debian 9 (stretch):

I'm trying to setup a Xen guest. I have installed Xen and now working on a Dom-0:

Now I'm trying to setup a bridge. I'm following the instructions in https://wiki.xenproject.org/wiki/Xen_Project_Beginners_Guide
My configuration file is:
$ cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
iface lo inet loopback
iface eth0 inet manual
auto xenbr0
iface xenbr0 inet dhcp
bridge_ports eth0
If I run sudo service networking restart it takes more than a minute.
Then the state of the bridge is strange:
$ sudo brctl show
bridge name bridge id STP enabled interfaces
xenbr0 8000.000000000000 no
The bridge has no real id and is not enabled.
I tried several different configurations for /etc/network/interfaces all of them failed.
Any ideas, why I can't setup a xen bridge?

The output is saying it has an id. STP a bridge negotiation protocol, not the bridge per se, and if nowadays it is by default enabled, so much the better. So, I think, your question as it is does not make sense.

The output is saying it has an id. STP a bridge negotiation protocol, not the bridge per se, and if nowadays it is by default enabled, so much the better. So, I think, your question as it is does not make sense.
