# HG changeset patch

# Node ID 36e0159c001b72969c5c9a9bf8bb48d8cfa932fa

This patch adds a boolean parameter 'network' to the save method of the
XendCheckpoint class to differentiate between network suspend/resume
(network=True) and local suspend/resume (network=False).
Instead of passing the 'live' parameter to the migration methods, this
'network' parameter is passed now. This ends up being merely a renaming
of the parameter.
A check with the xm-test suite against this change has resulted in no
additional errors.
