I don't get this point. What is the scenario?
For the crash of virtio frontend driver, i remember we discussed before,
we have no good recipe but some workaround. The user space frontend
driver crashes, and its memory is reallocated to other instances, but
vhost is still writing to that memory. However this has nothing to do
with vhost reconnect.
