2 Mark Wilson Infrastructure Architect/Technology lead for Windows Server 2008 and Hyper-V, Fujitsu Services

3 A community for everyone who is interested in Microsoft's Windows Server technologies - especially Windows Server 2008 Formed in 2007 – just getting started Have run a few events – more to come Find out more (join us!) at

4 Microsoft’s virtualisation platform {for the Enterprise}

5 What is virtualization virtualisation? Hyper-V architecture Installation of Hyper-V Management of Hyper-V Questions? (and hopefully some answers!) Stop Press! Whilst I was writing this presentation, Microsoft made a Hyper-V release candidate (RC) available. As a consequence, the contents of this presentation are based on the beta release – there may be some variations for RC (and RTM) releases.

7 The technologies {and the opportunity}

8 “ Virtualization essentially lets one computer do the job of multiple computers, by sharing the resources of a single computer across multiple environments. […] In essence, virtualization lets you transform hardware into software. Use software […] to transform or “virtualize” the hardware resources of an x86-based computer – including the CPU, RAM, hard disk and network controller – to create a fully functional virtual machine that can run its own operating system and applications just like a “real” computer. Multiple virtual machines share hardware resources without interfering with each other so that you can safely run several operating systems and applications at the same time on a single computer ” [Source: VMware website, March 2008]VMware website

9 Server consolidation Business Continuity Flexibility Utilisation

10 Computerworld “Although virtualization has been the buzz among technology providers, only 6% of enterprises have actually deployed virtualization on their networks, said Levine, citing a TWP Research report. That makes the other 94% a wide-open market.” The Rise of the Virtual Machine and the Real Impact It Will Have “We calculate that roughly 6% of new servers sold last year were virtualized and project that 7% of those sold this year will be virtualized and believe that less than 4% of the X86 server installed base has been virtualized to date. Pat Gelsinger, Intel VP Sept “Only 5% of servers are virtualized.”

11 Information Week Oct “The [virtualisation field] is nowhere near saturated. IDC estimates that only 17% of the worldwide server market will be virtualised by 2010, up from 5% in 2005.”

12 Cost Complexity Management Virtual sprawl Single point of failure Integration with physical infrastructure Software licensing and support Hardware Performance Political Security Concerns

19 32-bit (x86) and 64-bit (x64) virtual machines Large memory support (>32 GB) within VMs SMP VMs Integrated cluster support for quick migration and HA Volume shadow service integration for data protection Pass-through disk access for VMs Virtual machine snapshots New hardware sharing architecture (VSP/VSC/VMBus) Robust networking: VLANs and NLB DMTF standard for WMI management interface Support for full or server core installations

20 All child partitions are untrusted Root must be trusted by hypervisor; parent must be trusted by children Code in guests can run in all available processor modes, rings, and segments Hypercall interface will be well documented and widely available to attackers All hypercalls can be attempted by guests It is possible to detect that you are running on a hypervisor The internal design of the hypervisor will be well understood

21 No sharing of virtualized devices Separate VMBus to the parent for each child partition No sharing of memory Each virtual machine has its own address space VMs cannot communicate with each other, except through traditional networking Guests can’t perform DMA attacks because they’re never mapped to physical devices Guests cannot write to the hypervisor Even the parent partition cannot write to the hypervisor

22 Providing solutions for both planned and unplanned downtime Planned downtime Quickly move virtualized workloads to service underlying hardware – “quick migration” More common than unplanned Unplanned downtime Automatic failover to other nodes (hardware or power failure) – “live migration” Not as common and more difficult

37 Hyper-V: Microsoft’s new enterprise virtualisation platform Would you rather have 100% of VMware Virtual Infrastructure’s features (at a price), or 90% of the functionality (for much less)? There are some good built-in management tools, but SCVMM completes the picture (and is useful for multi-server deployments). In general: When many machines are consolidated, clustering becomes critical Promote standardisation by providing a library of pre-built VMs Use desired configuration management processes to trap and correct drift Remember that VMs still need to be patched, even when they are turned off Be prepared for support arrangements and license management to become more complex
