Additional Information

VMware HCX 4.11.1 Release Notes
Fixed Issue 3484210: In HCX version 4.11.0, users accessing the local plugin on vCenter versions earlier than 8.x are unable to configure VM placement when creating mobility groups.
This issue affects only HCX version 4.11.0 when using the local plugin on vCenter versions earlier than 8.x. In this scenario, users are unable to configure VM placement while creating mobility groups because the updated inventory widgets fail to load properly.
