WHY IT NEEDS A POLICY

Why update_vmware_dc needs a policy

This tool modifies VMware datacenter settings, which is a Write operation. Severity is high because misconfiguration of datacenter settings could impact infrastructure availability, networking, or resource allocation across multiple systems, though the effects are theoretically reversible. The CloudStack context as an infrastructure management platform amplifies the blast radius of configuration errors.

From the tool's definition Tool name 'update_vmware_dc' and description 'Update VMware datacenter' indicate modification of datacenter configuration. The term 'update' confirms reversible data modification rather than deletion or code execution.
