RE: [Xen-users] Debian & eth0 vs. peth0

[Joshua Kinard <joshua.kinard@xxxxxxxxxxxxx>]

Ah. I see.  I thought it was a Debian thing from some googling I did, as one 
site referenced something like (paraphrased) "In Debian, we have to do this 
...", and pointed the difference between peth0 and eth0.  Hence, I thought 
Debian instituted that change in their Xen packages.

Oh well, that's my mistake of the day!  Now if only setting up a proper apt 
mirror were a little easier....

Actually that's Xen's doing. Debian didn't change anything in the
naming convention. The naming was changed somewhere around Xen 3.3

I believe the naming was chosen for that particular purpose : since
users are used to eth0, and the IP is now moved to the bridge, then it
makes sense to name the bridge eth0. Try looking at
/etc/xen/scripts/network-bridge if you want to change it.

I prefer to do my own bridging setup though, using standard OS methods
(/etc/network/interfaces for Debian/Ubuntu) and dumping Xen's
network-bridge script altogether (comment-out network-script on
xend-config.sxp).
