so the solution for me to get all this automajic bridging to work is to add
this line to /etc/network/interfaces:
iface eth0 inet dhcp
Such that my /etc/network/interfaces look like:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
Then reboot.
That line seems to stop NetworkManager from managing that eth0 interface.
Which then seems to allow the /etc/xen/scripts/network-bridge script to be
successful.
Such that after the reboot, this is the output of `sudo ifconfig -a`:

I now have a "peth0" interface.
And the output of `sudo brctl show` now shows:
bridge name bridge id STP enabled interfaces
eth0 8000.0022192cb9db no peth0
Rather than showing the broken "tmpbridge" bridge.
and once I bring up a virtual machine with: `sudo xl create
/etc/xen/xen002.cfg`
I see that I have another interface successfully getting created on the dom0
machine:
vif1.0 Link encap:Ethernet HWaddr fe:ff:ff:ff:ff:ff
inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link

RX bytes:10898 (10.8 KB) TX bytes:88627 (88.6 KB)
NetworkManager still periodically (every 60 seconds) pops up a message of:
"Wired network. Disconnected"
so maybe I need to stop the NetworkManager service all together to stop its
pesky meddling with these newly created interfaces or at least have it stop
the irritating, and, I think, non-fatal messages.
I also now have ssh connectivity between my dom0 and domU and vice-versa.
(although, I have to use IP addresses and not the hostnames. Evidently, the DNS
server does not know about these hosts?)
So I think this "bug" can be closed, although it would be nice if the scripts
took into account Network Manager meddling and either provided a solution
inside the network-bridge script to disable NetworkManager temporarily
or spit out a message to the user about what they need to do.
