Sanjay Tripathi commented on CLOUDSTACK-7333:
---------------------------------------------

Verified using XenCenter, that this is a bug in XS 6.2.5. The issue is fixed in 6.5 as I am not able to reproduce this issue in 6.5.
We need to document this limitation. I'll open a doc ticket to track this.

> There are 4 scenarios which i tried :
> Setup :
> =============
> CS 4.5 advanced zone with Xen 6.2.5 + PV drivers ( XS Tools)
> Dynamic scaling is enabled on zone level.
> Scenario 1 :
> ====================================
> 1. Register a windows 8 or windows 2012 template ( without dynamic scaling enabled) and deploy a VM with vGPU service offering from it.
>  
>   -- Template is registered and VM is deployed. 
> 2. Install the PV drivers on the VM.
>   -- PV drivers are installed successfully (make sure they are latest)
> 3. Now stop the VM, enable dynamic scaling and start the VM.
>   -- VM fails to start and goes into the repair state.
> Scenario 2 :
> ====================================
> 1. Register a windows 8 or windows 2012 template ( with dynamic scaling enabled) and deploy a VM with vGPU service offering from it.
>  
>   -- Template is registered and VM is deployed. 
> 2. Install the PV drivers on the VM.
>   -- PV drivers fail to install and VM goes to repair state.
> Scenario 3 :
> ====================================
> 1. Register a windows 8 or windows 2012 template ( with dynamic scaling enabled and PV drivers installed) and deploy a VM with vGPU service offering from it.
>  
>   -- Template is registered and VM fails to deploy, it goes into repair state. 
> Scenario 4 :
> ====================================
> 1. Register a windows 8 or windows 2012 template ( without dynamic scaling enabled but PV drivers are installed) and deploy a VM with vGPU service offering from it.
>  
>   -- Template is registered and VM is deployed. 
> 2. Now stop the VM, enable dynamic scaling and start the VM.
>   -- VM fails to start and goes into the repair state
> Scenario 5 :
> ====================================
> 1. Register a windows 8 or windows 2012 ISO and deploy a VM with vGPU service offering from it.
>  
>   -- ISO is registered and VM is deployed. 
> 2. Install the PV drivers on the VM.
>   -- PV drivers are installed successfully (make sure they are latest)
> 3. Now stop the VM, enable dynamic scaling and start the VM.
>   -- VM fails to start and goes into the repair state
