I just followed http://kb.vmware.com/kb/2031729 to allow me to SSH from vCO to one of my hosts... once I confirmed SSH could connect successfully, I used my console to see what "services.sh restart" would do - it restarted a whole bunch of stuff and took a while to complete. Once I saw what to expect, I used the Run SSH command workflow to execute the same command... my results appeared to be the same as yours, but eventually the workflow DID complete after 14 minutes... It completes with a failed status though because some services were not running in the first place, so I would simply add an error handler to this workflow to let it complete successfully:
