[libvirt] [PATCH 3/3] Revert "libvirt domain xml allow to set peer address"

[Laine Stump]

This reverts commit 690969af9ccdf9b2012b97af0462bae8e312c9c9, which
added the domain config parts to support a "peer" attribute in domain
interface <ip> elements.

It's being removed temporarily for the release of libvirt 1.3.4
because the feature doesn't work, and there are concerns that it may
need to be modified in an externally visible manner which could create
backward compatibility problems.
