"I was just curious about them." :)
The default install for Debian includes all kinds of stuff, and I didn't see a
"small install" option so I just hit default.
Also even some command line Xen stuff pulled in tons of GUI code... :(

I already did that and there was no difference.

I normally use DHCP with MAC addresses, but I made a static entry:
iface eth0 inet static
When I do this, then brctl says this:
bridge name bridge id STP interfaces
eth0 8000.blah blah NO peth0
I don't get that... its listing eth0 as a bridge?
I put the following in /etc/network/interfaces (added):
iface br0 inet static
Then I get log messages saying "device eth0 is a bridge itself, cannot slave a
bridge to a bridge".
I'm confuzzled. When I last used Linux eth0 was the base ethernet device, not
a bridge, so none of this makes sense right now. This stuff does not work the
way the documentation says.
Now "ifdown eth0" results in "interface eth0 not configured", but its up.
ifconfig eth0 down
ifconfig peth0 down
That sequenced brings eth0 back up with no br0 in the configuration since I
can't create it anyway.
Still no work.
Will keep playing.

Yea I have all that, tried with and without the bridge statement.
