Public bug reported:
I was under the impression that the name of the default bridge would be "eth0"
(or "peth0" or "xenbr0"), instead I see "tmpbridge" as having been created.
In either case, I can't ssh to Dom0 from DomU, nor the reverse.
Nor can I ping any machine on the Internet from DomU.
I think xen-tools is not working correctly
on Ubuntu PrecisePangolin 12.04 with xen-tools 4.2.1-1.
I also see my Network Manager icon constantly reporting
that something has been disconnected every 30 seconds or so.
Output from `sudo ifconfig -a` on Dom0:

(dom0-min-mem 196)
(enable-dom0-ballooning yes)

(vncpasswd '')
I also will add that I don't think the syntax of naming a bridge works either.
Meaning, If I change the network-script line to
(network-script 'network-bridge bridge=br3')
I don't see anything get created named "br3".
I have zero experience with Xen so there may be a lot of user
error here but I am willing and able to provide more tests and information.
