Hi all, As some of you might recall, some time ago we made otopi default to python3, and quickly reverted that, realizing this causes too much breakage. Now things should hopefully be more stable, and I now merged a patch to default to python3 again. Current status: engine-setup works with python3 on fedora. host-deploy works with python3 on fedora, with both engine being on el7 and on fedora. Didn't try on el7, might work as well. hosted-engine --deploy is most likely broken on fedora, but I think it was already broken. We are working on that, but it will require some more time - notably, having stuff from vdsm on python3 (if not fully porting vdsm to python3, which I understand will take even more time). If you want to use python2, you can do that with: OTOPI_PYTHON=/bin/python hosted-engine --deploy On el7, if you manually added python3 (which is not available in the base repos), things will break - use above workaround if needed. Best regards, -- Didi
