4. Workload: The (New) IT Paradigm
Application
Workload Middleware
Operating System
A workload is an A workload is A workload or a
integrated stack of portable and collection of
application, middleware, platform agnostic workloads makes
and operating system –it can run in up a business
that accomplishes a physical, virtual or service, which is
computing task cloud computing what the end user
environments consumes

9. Server Consolidation – Why ?
Server consolidation is the process of migrating
physical server workloads into a virtual environment.
Challenges – Before Solution – After
•Too many physical servers •Consolidated servers
•Underutilized servers •Available floor space
•Limited floor space •Optimized resource utilization
•High power/cooling •Reclaim unused resources
consumption •Green IT/reduced carbon footprint
•Low ROI and high TCO •High ROI and low TCO

10. PlateSpin Migrate and ®
Workload Portability
• Enables hardware independent migrations of server workloads
(operating system, applications and data) across x86
server infrastructure
• Automates reconfiguration of resources assigned to workloads
• Supports virtual hosts and bare metal physical machines as
target platforms
• Reads data from various volume data sources to deploy or
recover machines
• Provides incremental P2V, V2V, P2I, and V2I migrations for
disaster recovery
• Ally Server Sync one time and perpetual incremental migrations

Xen Virtualization
• Integrated Xen hypervisor provides reliable,
high performance virtualization
• Xen 3.3.1 delivers advanced virtualization capabilities
• Lowest cost solution – Host is included with OS,
and you get unlimited VMs per system
• Additional management solutions are available
• Supports latest Intel processor and chipset-level
virtualization advances
– Intel VT FlexPriority
– Intel VT FlexMigration
– Intel VT for Direct I/O

Virtualization Host
• Upgrade to Xen 3.3.1 delivers
– Architectural improvements: better scalability,
performance and security
– Enhanced power management
– Improved graphical capabilities
• Open source management tools (virt-manager)
• KVM technical preview
• New paravirtualized drivers for Windows Vista and
Windows Server 2008

19. Xen Terminology

20. Xen Community Terminology
• Domain: A container for a running virtual machine.
Colloquially, the VM itself
• Domain 0: The first domain container created. Privileged
to affect (manage) other domains. a.k.a. “dom0”
• Unprivileged Domain: Any domain other than domain 0.
Cannot affect other domains. a.k.a. “domU”
• Driver Domain: Any domain that provides back end
services to virtual drivers. Typically this is dom0.
• Physical Driver: A device driver that talks directly to
the hardware
• Virtual Driver: A device driver in a domU that fulfills
requests by going to the physical driver in the driver domain
20 © Novell, Inc. All rights reserved.

21. Novell /Industry Terminology
®
• Hypervisor: The entity that enables virtualization
• Full-virtual: A VM mode that can run a native, unmodified
operating system by emulating all hardware devices
• Paravirtual: A VM mode that can run a modified operating system,
which cooperates with the Hypervisor
• VT Computer: A computer that contains processor(s) that support
virtualization technology, such as Intel VT or AMD-V. Required for
fully virtual mode
• Standard Computer: A computer that does not contain
processor(s) that support virtualization technology and therefore
can run VMs only in paravirtual mode
• Native Operation System: A typical operating system that is not
optimized for the paravirtual VM environment and must run in fully
virtual mode or on “bare metal”
21 © Novell, Inc. All rights reserved.

22. Novell Terminology ®
• VM Server: A server running Xen, or some other
hypervisor, capable of hosting VMs (i.e., xen + dom0)
> Example: SUSE Linux Enterprise Server 10 with the Xen packages
®
installed, booted with Xen
• VM: Virtual machines (domUs)
• Problematic terms
– “Host”, “Guest”, “Domain”
– “Host” and “Guest” suggest VMware's architecture
– “Domain” can be used synonymous with “virtual machine”
in the Xen community
22 © Novell, Inc. All rights reserved.

23. Virtualization Modes and
Xen Architecture

24. Virtualization Modes
Full-Virtual
– VMs can run native (unmodified) OS
Apps Apps
– Requires the need to trap and emulate
all privileged instructions*,
or emulate everything Operating Operating
System System
– Performance is negatively impacted
Virtual Virtual
– Also know as “HVM” virtual machines Machine Machine
(full-virtual) (full-virtual)
– Requires VT enabled CPU
Virtualization Layer
*Some processors are difficult to HW Platform
fully virtualize such as traditional x86
24 © Novell, Inc. All rights reserved.

25. Virtualization Modes
Paravirtual
– Higher performance than
full-virtualization Apps Apps
– Hypervisor is supplemented with Operating Operating
Management API
an API that provides an assist for System System
certain situations Virtual Virtual
Machine Machine
– Requires hardware dependent
API
(full-virtual) (full-virtual)
portions of the VM OS to be
modified to become aware of the Virtualization Layer
virtualization layer
– Allows VMs to avoid hard to HW Platform
virtualize instructions by replacing
them with a procedure call that
provides the same functionality
25 © Novell, Inc. All rights reserved.

26. Virtualization Modes
Virtualization Layer
Enlightened Virtualization
HW Platform
– Hybrid of full and paravirtualization
Apps Apps
– OS is “enlightened” to know about
paravirtual hypercalls
Management API
Operating Operating
– Some parts of the OS can use System System
paravirtual hypercalls other parts
Virtual Virtual
must use trap and emulation
Native
Machine Machine
API
(full-virtual) (full-virtual)
– Performance is improved Adapter
Requires VT enabled CPU
Native
–
Virtualization Layer
API
HW Platform
*For Windows Server 2008,
enlightenment requires a 64
