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 io

Boot up guest with 232 virtio-blk disk, qemu will abort for fail to
allocate ioeventfd. This patchset changes kvm_has_many_ioeventfds(),
and check if available ioeventfd exists. If not, virtio-pci will
fallback to userspace, and don't use ioeventfd for io notification.
