This has dropped to 4 patches vs 7 in v4. One of the delta is this
merging, what happened to the other two? Especially given that Ian J
asked for #7 to be split last time around.

Two patches in v4 are related solely to the bug fix. The first was by Ian while the other was by me, which Ian J asked me to split.

previous series either.

This is basically same as v3, with all the feedback.

Remus code other than a few little changes in the generic save/restore
code which are guarded by (in effect) if (remus). Is that correct?


If the only risk is to Remus users and the plus side is a far more
useful Remus then I'd say we should make a freeze exception, subject to
the code being reviewed of course.

Yes, these patches are confined totally to Remus' functionality in libxl. 

The other bug fix series otoh may need more testing as it touches domain suspend -- something core to both live migration and Remus. But that is a bug fix, not a feature addition.
