Target Milestone --- 

when using Virtio_user as Exceptio=
n Path ,configure the port in the primary
process , virtio_user do rx and tx in the secondary process. it generates a
mistake in tx such as (virtio_user_notify_queue(): failed to kick backend: =
Bad
file descriptor).

in my opinion ,when initialize the second process , is it properly to copy =
the
callfd and kickfd  which are initialized by primay process  to the secondary
process =EF=BC=9F in this situation =EF=BC=8Ci don't think  the secondary p=
rocess could find
the correct kickfd  ,and it make kthread work  abnormal.

please see the question ,thank you !!!
