Well there's a huge amount of detail needed here. The idea is that
memory_region_add_eventfd() will always work, with or without kvm, and
even if kvm is enabled but we run out of ioeventfds.
One way to do this is to implement core_eventfd_add() in exec.c. This
is unlikely to be easy however.

But other users will silently break, need to audit all other users of
ioeventfd, for example ivshmem.
