Feature Specifications

...

This feature is to support multiple network interfaces to guest vm's by following operations

• • Deploy VM with multiple networks
  • Add Network to VM 

Hyper-V have a limitation of dynamically adding NIC to a VM which is in running state. To add a new NIC to a VM on hyper-v it should be in stopped state.

Multiple nic for the VM will be supported only when VM is in stopped state or during VM Deployment.

• list what is deliberately not supported or what the feature will not offer - to clear any prospective ambiguities
  • This feature is supported only when the VM is in stopped state.
  • VM can be added to Max 8 Networks.
• quality risks (test guidelines)
  • functional
    • While deploying the VM,select multiple networks. VM will be created with multiple nics and will have configured guest Vlan's on the nic.
    • When Add network to VM, if the VM is in stopped state it should be successfull
    • When Add network to VM, if the VM is in Running state, Error will be shown Message "Vm in Running state cannot be addeded to new network" will be shown 
    • for a VM it can be Max on 8 networks. This is because of the Number of Nic's limitation imposed by Hyper-V
  • corner cases and boundary conditions
  • negative usage scenarios
  • specify supportability characteristics:
    • what new logging (or at least the important one) is introduced
    • how to debug and troubleshoot
    • what are the audit events 
    • list JMX interfaces
    • graceful failure and recovery scenarios
    • possible fallback or work around route if feature does not work as expected, if those workarounds do exist ofcourse.
    • if feature depends other run-time environment related requirements, provide sanity check list for support people to run
  explain configuration characteristics:
  • configuration parameters or files introduced/changed
  • branding parameters or files introduced/changed
  • highlight parameters for performance tweaking
  highlight how installation/upgrade scenarios change
  • • • When user tries to Add Network to VM when VM is in running state. Error Message "Vm in Running state cannot be addeded to new network" will be shown.
      • When user tries to Add Network to VM when VM is in stopped state and the number of networks is more than 8, then Error Message "Maximum 8 networks will be supported"  will be shown.

  Support-ability Characteristics

  Logs can be looked up at the following location

  • • The Hyper-V agent logs can be seen in windows event viewer on the respective hosts. The logs can be filtered by source "CloudStack Hyper-V Agent".
    • Hyper-V specific logs can be viewed in the event viewer under "Application and Services Logs" >> Microsoft >> Windows >> "Hyper-V-VMMS".

  
  

  • deployment requirements (fresh install vs. upgrade) if any
  • system requirements: memory, CPU, desk space, etc
  • interoperability and compatibility requirements:
    • OS
    • xenserver, hypervisors
    • storage, networks, other
  • list localization and internationalization specifications 
  • explain the impact and possible upgrade/migration solution introduced by the feature 
  • explain performance & scalability implications when feature is used from small scale to large scale
  • explain security specifications
    • list your evaluation of possible security attacks against the feature and the answers in your design* *
  • explain marketing specifications
  • explain levels or types of users communities of this feature (e.g. admin, user, etc)

  Supported Hypervisor

  This feature is implemented for Windows Server 2012 R2 and Hyper-V 2012 R2 (Core).
