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
