XCP by default use OpenVSwitch, which capable to provide bonding.

bridge (xenbrX) is placed between bonding and virtual interfaces.

After I have create a test bond from XenCenter, I have noticed that what was actually created on the host is not a "bond" (as described in http://www.kernel.org/doc/Documentation/networking/bonding.txt ), but a bridge. This is confusing, I was expecting something like a 802.3ad interface, that would need cooperation from the the switch (group ports into a LAG).

I guess I'm missing something. Is there some layer behind this bridge, that makes it act like a bond? Does it need any special configuration at switch's side? Why do they call "bond" a bridge, anyway? Surely there is a good reason, but I'm curious which is.

Greetings.
