[libvirt] [PATCH] Allow no <source> for bridge interfaces

# HG changeset patch # User john.levon(a)sun.com # Date 1233586907 28800 # Node ID 68087e3caf39c74797720bde71a8df524ec036c8 # Parent aa50ca252e1419f30eb0e16204b48db42d92c785 Allow no <source> for bridge interfaces Historically, it was allowed to specify a bridge interface without a specific bridge source, in which case xend would choose one. Keep compatible with this behaviour.
