[Avocado-devel] Passing test parameters on the command-line?

[Sergey Bronnikov]

Hi,

there are many ways to do it.
Avocado can read parameters via command line, config files (aka cartesian
config) and YAML configs.
Parameters from all these sources are merged together before run and used
in tests.
Avocado prints parameters used in test before running it (see output with
--show-job-log).

The simpliest way for you is using command line. Just pass qemu_bin value
via extra params:
$ avocado run --show-job-log io-github-autotest-qemu.boot --vt-extra-params
qemu_bin=/bin/true
or special special option for overriding QEMU binary - "--vt-qemu-bin":
$ avocado run --show-job-log io-github-autotest-qemu.boot --vt-qemu-bin
/bin/true
