I haven't run IMGPROTO + IMGFMT tests but looking at the code it should work. The "Header extension too large" error message comes from block/qcow2.c so it seems the header data is corrupt. I suggest running "./check -pvfs2" first to make sure it passes the raw image tests. Once that seems okay it's worth looking into issues from "./check -pvfs2 -qcow2" and installing/running guests.
