And building from sources proved to be reasonably easy, so the test
now passes for me.  My initial thought of putting qemu-x86_64 into
my ~/bin directory fails the sudo test, but putting it into /usr/bin
works fine.

Thank you for the hints!

Should I add a sentence to the commit log noting the potential need to
build qemu from the git repo and to install qemu-x86_64, give or take
what architecture one is running?
