[ovirt-users] Current Architecture of oVirt and Quality Assurance measures

I am currently evaluating oVirt for the usage in big companies as base system for edge computing applications. I already tried to find a current architecture overview regarding the oVirt modules -- particularly ovirt-node-ng and imgbased. But I did not manage to find any. There is some architecture documentation, but marked as outdated and many links go to 404. So I would ask, if somebody could provide any current architecture overview (no user documentation), particularly of the node module(s). An other question I have, is which quality measures are used in development? * Tools used (for Unit-Tests, Component-Tests, Integration-Tests) * Are there any statistics about test coverage? Any assistance would be appreciated. Best Regards /juergen
