Any update?
If we can't solve it soon, I suggest to revert the patch for running log
collector in the meantime, because we risk of having new regression coming
it,
and its our only way to verifying if master is broken or not.
Another option is to move master to work with API V4, which we should do
soon probably, but I don't know how long that can take and who can do it.

Hi Juan,
I managed to reproduce this with "basic_suite_master" test from
ovirt-system-tests, that uses everything from master branch. 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". Here you can find
the xml output of the endpoints you asked: https://gist.github.com/
rafaelmartins/60c21e158a9e6453c14a673f77693d61
Please let me know if you need anything else.
Thanks,
Rafael
