xen discuss - Jun 2009 - link coupling for host interconn

Is there a good way to combine two gbit direct links between two xvm 
nodes to speed up livemigration beyond the limits using a single gbit 
connection?
Also it should offer redundancy.

Link aggregation is nice but doesn''t affect a single transfer or is the
live migration a multi connection action in the means of the 
distribution policies off a link aggregation, and what policy would 
serve this best then?

Migration traffic travels in a single TCP connection, so you are right
that aggregating multiple gigabit links doesn''t help.

I don''t see a way to improve things today without buying faster links.
