FIX: Qemu path override
Currently there is bug that Qemu path is not correctly composed and cannot be properly overriden due to race condition in code. This patch is fixing functions to properly work with path. Change-Id: I276458d2d23c7a14441a4de4a56eff6431242ab9 Signed-off-by: Peter Mikus <pmikus@cisco.com>
