You're not providing sufficient details for the upstream community to
help you, so CC'ing the Debian maintainer. "qemu" sounds rather old,
it's qemu-system-i386 since several versions already.

Did you check that you have sufficient RAM on your Raspi? Or disk space
on your SD card / USB disk? Disk images are created sparse, and when the
host runs out of resources lots of things can happen.

qemu-i386 can execute individual Linux binaries, with a bunch of known
issues. Might or might not work for you - you don't say what you
actually want to do.

Yes. The disk image is just a file.
