[Qemu-devel] RFC: savevm/migration support for pseries

[David Gibson]

Hi Alex, Juan,

This large patch series contains the full set of patches to add
working migration support for the pseries machine.  This includes
converting target-ppc to new-style VMStateDescription, at the same
time reworking it thoroughly to correct many bugs.

As far as I know, no target-ppc machines other than pseries will have
working savevm with this patch series, but as far as I can tell none
of them had working savevm before.  The rework of the target-ppc
savevm code should get them closer, but there's still work to be done
on the other machines' platform and system device state (openpic/mpic
in particular has completely broken savevm support).

For now this is RFC only.  Please review, but do not apply for the
time being (excepting, Alex, 1-2/15 which are just preliminary
cleanups).  I don't consider the savevm serialization format versions
introduced by this series as being frozen just yet.
