100%

Steps to Reproduce:
1. Register a VHost KVM system to Satellite
2. Set the following entitlement

    Virtualization Platform

NB: Do not set Provisioning Entitlement.
  
3. Create Kickstart for KVM Guest
4. Systems -> VHost -> Virtualization -> Provisioning  
5. Fill all required fields, mark "Do not use an RHN Satellite Proxy"  and press "Shedule  Kickstart and Finish" (See Screenshout 1)
6. You are redirected to "Session Status" Tab (See ScreenShout 2 )
7. Try to get to Tab labeled as "Shedule" 
   "Permission Error" (See ScreenShout 3)
8. System -> VHost -> Virtualization -> Provisioing ...
   
  
Actual results:
