Hi,
That helped a lot, thanks :-) I think I'm almost there. After running: ./virtualenv/bin/teuthology --archive /tmp/a1 /srv/3node_rgw.yaml wget -O /tmp/build/tmp.tgz http://gitbuilder.ceph.com/ceph-tarball-precise-x86_64-gcov/sha1/$(cat /tmp/a1/ceph-sha1)/ceph.x86_64.tgz echo ceph_build_output_dir: /tmp/build >> ~/.teuthology.yaml ./virtualenv/bin/teuthology-coverage -v --html-output /tmp/html --lcov-output /tmp/lcov --cov-tools-dir /srv/teuthology/coverage /tmp I get INFO:teuthology.coverage:initializing coverage data... Retrieving source and .gcno files... Initializing lcov files... Deleting all .da files in /tmp/lcov/ceph/src and subdirectories Done.

They are both amd64 but .gcno files may have dependencies to the toolchain. Did you ever run into similar problems ?
