Last year the Avocado developers said we could have a clearer
log error report, but meanwhile this verbose output is better
that not having anything ¯\_(ツ)_/¯

"No QEMU binary defined or found in the build tree" is not a
problem, it means a test is skipped because the qemu-system-$ARCH
binary is not found. In your case this is because your job
(acceptance-system-fedora) is based on build-system-fedora
which only build the following targets:

    TARGETS: tricore-softmmu microblaze-softmmu mips-softmmu
      xtensa-softmmu m68k-softmmu riscv32-softmmu ppc-softmmu
      sparc64-softmmu

Now I don't understand what binary the EmptyCPUModel/Migration tests
are expecting. Maybe these tests only work when a single target is
built? IOW not expecting that the python code searching for a binary
return multiple ones? -> Eduardo/Cleber.

w.r.t. the error in your build, I told Thomas about the
test_ppc_mac99/day15/invaders.elf timeouting but he said this is
not his area. Richard has been looking yesterday to see if it is
a TCG regression, and said the test either finished/crashed raising
SIGCHLD, but Avocado parent is still waiting for a timeout, so the
children become zombie and the test hang.

Not sure that helps :)
