Re: [ovirt-devel] Failure in log collector on master: Failure fetching information about hypervisors from API. Error (ValueError): legacy is not a valid RngSource

Interesting that we don't see it on 4.0, saw it's a regression introduced somewhere, or a test case we have not seen before? Y.

This means that engine version is 4, not 3. It seems to be an issue with engine/sdk, as the value is actually stored on engine as "legacy".
