Probe mode reveals information about the content of a source. You can probe OVA and OVF packages, VMX, and vSphere source types. You can then use the information gathered to find out how it can be configured when you deploy it.

To use the probe feature, omit the target locator when invoking OVF Tool. For example, type: ovftool LAMP.ovf at the command line. OVF Tool displays all available information about the LAMP.ovf package.

When probe mode is used on an OVF or OVA package, OVF Tool also validates the certificate file, if present. As of vSphere 8.0 U2, OVF Tool probe mode also detects and handles the virtual TPM (vTPM) device.

As part of the information displayed in probe mode, the EULA is displayed by default. To prevent the EULA from displaying, use the --hideEula option.
