I may not have described it clearly.  

i need to ensure  the order of  adding port to bridge and deleting from bridge.

i  rename tap device to avoid the problem  in my first patch.i think it can 
solve the problem.

my second patch may can't resolve the problem .

Do you  have any better ideas?

thanks

That still does not make sense. There is no difference in the way tap devices
are cleaned up whether QEMU exits "normally" on its own, or when libvirt kills
QEMU explicitly
