  1. Intro to Virtualization Andrew Hamilton TJ IT Technician

  2. Theory • Do one thing and do it well (UNIX philosophy) • Compartmentalize Services • Benefits of many systems in one

  3. Advantages • Security • Access Control • Upgrades • Potential for High-Availability Clustering • Resource management

  4. Disadvantages • Overhead • Proliferation of systems • Upgrades

  5. Virtualization Types • Containers • Very minimal overhead • Only one OS • Paravirtualization • Minimal overhead • OS must support the hypervisor • Full Virtualization • Runs almost anything • Often high overhead

  6. Microsoft Hyper-V • Full virtualization / Hypervisor • Primarily Supports Windows Server Oses • Free version available

  7. Solaris Zones/Linux Containers • Container Solutions • Extremely low overhead • Shares kernel with host OS • VM Filesystems mounted in host system

  8. Solaris LDOMs • Full virtualization solution • Only available on UltraSPARC servers • Support for non-Solaris is iffy

  9. Linux Kernel Virtual Machine • Full Virtualization solution • Leverages hardware virtualization extensions • AMD-V / VT-x • Low overhead • Works with most operating systems

  10. Oracle Virtualbox • Full Virtualization • Works with most Oses • Higher overhead • Can use AMD-V/VT-x • Primarily for desktop virtualization

  11. Microsoft Virtual PC • Full Virtualization • Works with most Oses • Higher overhead • Some versions require AMD-V/VT-x • Primarily for desktop virtualization

  12. VMWare • Full Virtualization / Hypervisor • Works with most Oses • Can use AMD-V/VT-x • Well-supported

  13. Xen • Hypervisor Paravirtualization • Low overhead • OS must support Xen (primarily Linux) • Can leverage AMD-V / VT-x

  14. Example • TJ Computer Systems Lab • Xen Virtualization with Gentoo Linux • 6 VM Servers • ~25 VMs
