Ok, so your QEMU process has not in fact died completely, so the
libvirt state is correct.

Usual cause of a qemu going into a defunct state is a storage
failure which causes QEMU to be stuck in an uninterruptable
I/O operation wait state.

No, as you see from the logs above, libvirt already tried to
send a SIGKILL and it had no effect. You need to figure out
what has caused QEMU to get stuck - most likely a storage I/O
problem on your machine
