Currently the oVirt provider uses version 4.0.z of the oVirt Ruby SDK. This version of the SDK works correctly with version 4.0 of oVirt, but it can't use the new features introduced in version 4.1 of oVirt, which was recently released.
In addition, even if no new oVirt 4.1 feature is used by ManageIQ, version 4.0.z of the SDK does not understand new enum values introduced in oVirt 4.1, which may cause issues for users upgrading their oVirt environments before upgrading their ManageIQ environments. This has been addressed in version 4.1.z of the SDK, and also in version >= 4.0.12.
As version 4.1.z of the SDK is backwards compatible with 4.0.z, upgrading to 4.1.z is safe. If that is considered risky, for whatever the reason, then it should be updated to 4.0.12 at least.
The pull request that addressed this issue is this one:
Update oVirt SDK to 4.1.z
