 Show (bring to front)
 Pause
 Reset
 Close
– Save state
– Send Shutdown signal
– Poweroff
 Discard saved state
 Show in filesystem
 Sort
Groups Operations
VBoxManage list groups
VBoxManage createvm --name <name>
[--groups <group>, ...]
VBoxManage modifyvm <uuid|name>
[--groups <group>, ...]

VirtualBox Power
Online Snapshot creation AND deletion

Virtual Machine Clones
• Full Clones
– Full copy
– Disk UUIDs automatically made unique
– Optionally MAC addresses made unique
– VirtualBox Manager and CLI
• Linked clones
– VM config is copied
– A snapshot is taken at source
– The clone uses a child differencing disk with
source snapshot as parent
Easily duplicate virtual machines

VirtualBox for developers
31

Developer challenges
• “Write once, run anywhere” still not reality
– Need to build for and test on multiple platform combinations
– Multi-platform products can require a lot of hardware to create, test, ship, support
• Test / experiment sandboxes
– Takes time, human effort, physical resources to set one up on bare metal
• Or preserve an old environment that a customer is still running
– Hard to snapshot an entire environment or revert it to a known-good point
• If it’s hard for me to fall back to a known point, I might be less adventurous trying things out
• Platform deployment challenges
– Different kernel, library, compiler, product installer versions to build on and test to
32

How developers can use VirtualBox
• Stand up virtual machines for each build/test case
– Script VM creation using VBoxManage to reduce effort, get reproducible VMs
– Create families of VMs for complex apps (eg: database, app, and access VMs)
• “Build system” VMs to create binaries for different target systems
– Different operating systems (eg: Linux, Solaris, Windows)
– Different variants of the same OS (eg: Oracle Linux, Red Hat Linux, Ubuntu, SuSE, etc)
– Different generations of the same variant (eg: Solaris 10, Solaris 11)
– Different language environments (eg: different JVM, gcc versions, libraries)
33

How developers can benefit from VirtualBox
• Test/regression/support VMs
– Same patterns as OS and software environment, plus ability to test
• Different network topologies
• Different memory (including stress states like “low memory”), disk, CPU configurations
• Different security policies
– Run many tests in parallel to limit of capacity
• Be able to reproduce customer environment (within reason)
• Other uses:
– Training, demos, new hire onboarding in a safe place
– Document team workspaces
34

How developers can use VirtualBox
• Safe experimentation:
– Import VMs from a library of “ready to run” VM appliances for each supported flavor
– Take a VM snapshot before and after making an “interesting” change
– Clone VMs for parallel test runs
– Revert to a VM snapshot or clone at a given snapshot level
– Export VM appliances for reuse
– Use for:
• Program changes
• Multi-host simulation
• “What if” scenarios
35

Example VirtualBox developer use cases
36

Oracle VM under VirtualBox
Screen capture of (from left to right, top to
bottom)
• Console of Oracle Linux VM running under
Oracle VM Server (itself a VM)
•Console of Oracle Linux VM running Oracle
VM Manager
•Console of two Oracle VM Server VMs
Notes:
•3rd level guests must be PVM guests, and
don’t get virtual network connectivity
•iSCSI, NFS both work
•Live migration of 3rd level VMs between
OVM servers works
37

VirtualBox for Virtual Machines
Oracle VM, and Oracle Virtual Compute Appliance
• Oracle VM Compute Appliance is Oracle’s Engineered System for Oracle VM
– Converged Infrastructure combining compute, networking, and storage with the
Oracle VM virtualization product pre-installed
• Two management nodes for orchestration and administration
• Two or more Oracle VM Servers (“compute nodes”)
• ZFS storage appliance
• Oracle Virtual Networking and datacenter switches
• Virtual Compute Appliance “orchestrator” discovers and provisions servers
• Wouldn’t it be nice to have a simulated environment for demo, test, etc?
• VCA simulator uses VirtualBox to host VMs that run the management,
compute, storage and network components (and their iLOMs)
38

Summary
43

VirtualBox for Developers
• Powerful platform to run multiple VMs on the same host system
• Features attractive to developers:
– Support for wide range of host and client VM operating systems
– Snapshot, clone, revert
– Export/import appliances
– Powerful network configuration options
– Advanced display support
– Highly programmable and scriptable
– Easy: it doesn’t get in your way; short learning curve
