[Qemu-devel] [RESEND PATCH 0/2] Fix rtl8139 migration with hotplug

[Alex Williamson]

rtl8139 includes a cpu_register_io_memory() in it's vmstate.  This
is problematic if the guest undergoes hotplug operations, which can
shift io indexes between migration source and target.  Add an
interface to detect this condition and add a subsection, when
necessary, to ensure we migrate to a safe target.

This resolves Juan's concerns about maintaining the migration ABI
and Michael's concerns wrt subsections.  Acked by both.  Please apply.
Thanks,

Alex
