I'm tracking down a image corruption issue and I'm curious if you can
answer the following:
1) Is there any difference between sending a "TERM" signal to the QEMU
process and typing "quit" at the monitor?
Yes. Since QEMU is single threaded, when you issue a quit, you know you
aren't in the middle of writing qcow2 meta data to disk.
2) Will sending TERM corrupt the 'gcow2' image (in ways other than
normal guest OS dirty shutdown)?
Possibly, yes.
3) Assuming I always start QEMU using "-loadvm", is there any risk in
using 'kill' to send SIGTERM to the QMEU process when done?
Yes. If you want to SIGTERM QEMU, the safest thing to do is use -snapshot.
