Are you using qemu:///session maybe? Then the logs will be in
~/.cache/libvirt/qemu/log/ . The log file is the the canonical location
to find the qemu command line that libvirt is generating

Aha. I have the command-line now. Thanks :) Full log:

If I run that command directly, I get:

2019-02-18T12:36:09.947298Z qemu-system-x86_64: -object secret,id=masterKey0,format=raw,file=/home/dkasak/.config/libvirt/qemu/lib/domain-1-Android-x86/master-key.aes: Unable to read /home/dkasak/.config/libvirt/qemu/lib/domain-1-Android-x86/master-key.aes: Failed to open file “/home/dkasak/.config/libvirt/qemu/lib/domain-1-Android-x86/master-key.aes”: No such file or directory

If I remove the line that mentions master-key.aes, I get:

If I remove the line that mentions fd=20, I get:
