VMware Infrastructure Management Assistant (VIMA) was released recently.
VIMA allows administrators and developers to run scripts and agents to manage ESX and ESXi systems. VIMA is a VM that includes prepackaged software, a logging component, and an authentication component that supports non-interactive login. VIMA can be used to perform most of the tasks commonly performed in the ESX service console.
VIMA 1.0 is available for downloaded immediately on the VMware website.
