From: David Jacobson <djacobs7@binghamton.edu>

Regression testing kernels is a task that is often virtualized. This
patch adds functionality to evmtest that enables a developer to
determine if their kernel build is suitable for running in a virtual
machine.

Signed-off-by: David Jacobson <djacobs7@binghamton.edu>

changelog:
* shellcheck compliant
* updated patch to work with function restructure
