According to Ed this commit fixes the failure: commit 1b32c6ed025745cb06b7c28ca0fe9e416ce7abfa Author: Ed Bartosh <ed.bartosh@linux.intel.com> Date: Sat Dec 3 01:48:06 2016 +0200 selftest: wic: fix test_qemu Setting WKS_FILE variable in qemux86-64 made wic test to use wrong wks file to produce an image and resulted in test_qemu failure. Used conditional assignment in qemux86-64 and explicitly set WKS_FILE in wic testing suite to make the suite to use wic-image-minimal.wsk. This should fix test_qemu failure.
