I'm not sure I understand what you mean here.

TFTP server support is builtin to qemu, once guest goes down so does TFTP.
To access host data from guest is then no problem, but to access data on guest
from host, you need to explicitly upload that data on the TFTP server - which
will copy the data on the host.

Infinite complexity begets infinite beauty.
Infinite precision begets infinite perfection.
