Hi,
I checked the FD information with the command "ls -l /proc/25977/fd" // here 25977 is Qemu process.
I found that the creation timestamp of the FD was not changed, but the socket information to which the FD was linked was changed.
So, I guess the FD is reused when establishing new tcp connection.

The tcp may be long connections.
