  • 14. Terms
    Virtualization Host, VM Host, Host
    Virtual Machine, VM
    Guest
    Virtual Server?
  • 15. Types of Virtualization
    Desktop
    VMware Player
    VMware Workstation
    VMware Fusion
    Parallels Desktop
    MSFT Virtual PC
    Virtualization S/W
    Host OS:
    Windows 7,
    Linux, etc.
  • 16. Types of Virtualization
    Server
    VMware Server
    Parallels Server
    Oracle VirtualBox
    MSFT Virtual Server 2005
    Virtualization S/W
    Host OS:
    Windows Server,
    Linux, etc.
  • 17. Types of Virtualization
    Hypervisor
    VMware vSphere
    MSFT Hyper-V
    Xen
    Parent Partition,
    Dom0,
    Console OS
    Host “OS” is the
    Hypervisor
  • 18. Microsoft Hyper-V
    Standalone (Hyper-V Server), or
    Windows Server 2008 (x64) Hyper-V Role
    Hyper-V Server is FREE
    Manage with System Center Virtual Machine Manager (SCVMM)
    H/W: Intel-VT + XD, AMD-V + NX
    Guest support: Windows, RHEL, SuSE
  • 19. VMware vSphere
    aka ESXi, ESX, Virtual Infastructure, VI3
    VMware vSphere Hypervisor is FREE
    Paid versions have more features
    Manage with VMware vCenter
    H/W: Consult HCL
    Guest support: Almost anything
  • 20. Citrix XenServer
    FREE
    Paid versions have more features
    Manage with XenCenter
    H/W: Intel-VT, AMD-V (Windows guests)
    Guest support: Windows, Linux
  • 21. Which is best?? ….
  • 22. Define “Is”
    vSphere
    Most third party tools and vendor partnerships
    Leading in advanced features
    Can quickly get expensive
    Hyper-V
    Familiar management for Windows people
    More features for free (Live Migration)
    Less VM density
    XenServer
    Familiar management for Linux people
    Most features for free
    Better density with Linux guests
  • 23. Benefits(COMMUNITY)
  • 24. Agility
    A new VM is a few clicks away
    Add as many VMs as host capacity allows
    “Think about trying to get the OK to purchase a physical server for something that only benefits IT.”
  • 25. Windows Licensing
    Server 2008 Enterprise license allows for 4 VM instances on same host
    Server 2008 Datacenter license allows for unlimited VM instances on same host (license per host CPU)
    Applies to any virtualization platform
    Additional benefit for Hyper-V Role:Host license includes guest license(s)
  • 26. Oversubscription
    Memory Oversubscription
    Paging, deduplication, compression, etc.
    Microsoft “any day now”
    Disk Oversubscription
    “Thin provisioning”, “Expanding”
  • 27. Backups
    VMs are just files
    copy, rsync, scp works for these too
    VeeamFastSCP
    Veeam Backup
    Trilead VMX
  • 28. Reduced Downtime
    VMs are portable between hosts
    Storage shared across VM hosts
    Restore backup to another VM host
    Run from backup using VMware Player
  • 29. Advanced usage
  • 30. Snapshot
    .vmdk
  • 31. Snapshot
    undo.vmdk
    base.vmdk
  • 32. Snapshot
    undo.vmdk
    base.vmdk
  • 33. Rollback
    undo.vmdk
    base.vmdk
  • 34. Non-Persistent
    I install Spiceworks in a VM 5-10 times per week.
    Every “Power Off” or “Restart” performs automatic Rollback
    scsi0:0.mode = "independent-nonpersistent"
  • 35. VDI
    user1.vmdk
    user2.vmdk
    base.vmdk
  • 36. Virtual Networking
    Bridged
    Host Only
  • 37. DIY Bridge
  • 38. Lossy Network
