You should *never* run  /usr/libexec/virt-sandbox-service-util directly. The virt-sandbox-service command is the only one that should be tested. It will internally run virt-sandbox-service-util *if* required.

The current virt-sandbox-service does not use  /usr/libexec/virt-sandbox-service-util for executing commands anymore, so you were testing dead code here. Please re-test using  'virt-sandbox-service execute.....' instead.
Comment 3 dyuan 2013-07-10 05:15:29 UTC 
Okay, thanks. Will not test it anymore, and remove it from the test plan.

And it's okay for virt-sandbox-service. So I'll close this bug as WONTFIX.
