Description

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
