Feature Specifications

This feature enables VMware distributed vSwitch in CloudStack to configure and manage virtual networks over dvSwitch instances in datacenter of the managed cluster.

1. CloudStack does following,
   1. Create dvPortGroup over designated dvSwitch
   2. Modify dvPortGroup over designated dvSwitch
   3. Delete dvPortGroup over designated dvSwitch
2. CloudStack doesn't do following,
   1. Create dvSwitch
   2. Add host to dvSwitch
   3. Dynamic migration of virtual adapters of existing VMs across differnt types of virtual switches in scenarios in which co-existance of multiple types of virtual switches (Cisco's Nexus 1000v or VMware standard vSwitch and dvSwitch) is possible. Instead this is left to administrator to decide.
   4. Configuration of PVLAN
   5. Configuration dvPort mirror
   6. Configuration of user defined network resource pools for Network I/O Control (NIOC)

  • non functional: performance, scalability, stability, overload scenarios, etc*
• ***Large number of VMs and isolated networks need to be tested for performance specific results.
• negative usage scenarios - NA
• what are the audit events *
  • ***All virtul network orchestration events ***
  • VM migration events
  • 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 on other run-time environment related requirements, provide sanity check list for support people to run
• #Basic # Basic sanity testing over dvSwitch can be done. It might be ping operation from one VM to another VM in the same network. Make sure VLAN configuration is done in that network and verify isolation is achived or not.
• #Verify # Verify if traffic shaping policy configured is applied and working.
