 Virtualization infrastructure & Virtual Appliances
 Virtualization technical benefits in software testing
 Risks and security concerns
 Mitigation and Testing Approaches

3. Virtualization infrastructure:
 Server or platform virtualization
 Storage virtualization
 Network virtualization
Virtual Appliances:
• A virtual appliance is a virtual machine image
designed to run on a virtualization platform (e.g.,
VirtualBox, Xen, VMware Workstation, Parallels
Workstation)

4. Virtualization technical benefits
 Easy environment administration
 Duplicating / recreating intermittent problems
 Agile deployment / testing
 Portability (Moving / Copying VMs)
 Snap shot
 Server consolidation
 Testing of software concurrently
 Disaster management
 Many more…

5. Virtualization Challenges
 Hardware Limitation
 Virtual driver unavailability
 Hardware network implementation / deployment
 Hardware watchdog
 Hardware clock
 Serial console not available
 VLAN support / other network related service support
 Directly export ovf file for Virtual appliance
 Availability of test automation tools
 Resource constraints
 Performance testing
 Hardware compatibility testing

6. Mitigation
 Assessing Infrastructure Risks
 Assessing Features Risks
 Test plans and for Virtual Test requirements
 Naming convention for VMs
 Base images granularity analysis
 Network and its related services identification &
address conventions
 Test data preparation

7. Mitigation (cont..)
 Establish a base library of images
 Create a Library of ISO files
 Manage virtual machines as if they were physical
machines
 configure anti-spyware / anti-malware exceptions
◦ *.vhd, *.vud, *.vsv, *.iso
 Managing Performance
 Monitoring Approach
 Getting Virtual edition software
 Implementing Service Virtualization
 Assessing Management Risks
