[Xen-devel] [PATCH v2 0/3] Introduce migration precopy policy

[Jennifer Herbert <Jennifer.Herbert@xxxxxxxxxx>]

Hi all,

v2:

Have tidied some formatting, s.o.b Joshua, and added a RFC patch
showing how to use this in  libxl.

v1:

Here I present a updated/modified subset of patch 7/20, part of
Joshua Otto's "Add postcopy live migration support." patch,
dated 27th March 2017.  As indicated on the original thread,
I wish to make use of this this within the XenServer product,
and hence am trying to get this subset  pulled in now. I also
hope this will aid Josh in pushing the remainder of his series.

Here I present two patches, the first which does some tidy up, removing
unused and unhelpful paramaters to xc_domain_save(), and the second
which allows a precopy callback to be specified, providing the
test for when to end the live phase of migration should end.
If none is provided, a default policy of the current behaviour
is used.
