What I meant to say was that I want to apply following rules of "migrate" to "vcpupin". ***migrate*** - when option <desturi> error It outputs error message in "vshCommandCheckOpts". error: command 'migrate' requires <desturi> option - when internal-error occurs at "vshCommandOptString" It outputs error message after "vshCommandOptString". migrate: Missing desturi ***vcpupin*** - when option <cpulist> error It outputs error message in "vshCommandCheckOpts". error: command 'vcpupin' requires <cpulist> option - when internal-error occurs at "vshCommandOptString" ***no error-message, and return 1*** ->I want to output error-message here, because I want to tell an error to a user.
