“Why is virtualization such a big deal? A lot of people understand, and they think it's about saving money, it's about saving power, it's about green IT, it's about space, and that's certainly true. But in our perspective, it's much, much bigger than that, and people are just now beginning to understand that. We think that there's a major transformation taking place in IT. This major transformation that's been taking place for years is starting to accelerate, and we believe that virtualization is a major enabler and catalyst of that transition that's taking place.”
- Tom Bittman, Gartner VP and Chief of Research of Infrastructure and Operations, at Microsoft’s Virtualization Launch Event

Increasing AvailabilityLive Migration
Migrate virtual machines between hosts with no interruption of service
Benefits:
No dropped network connections
High availability for production workloads
Flexible management
Enables dynamic IT environment

Live Migration
Moving a virtual machine from one server to another without loss of service
Enables new dynamic scenarios
Guest OS is unaware of the migration
Maintain TCP connections of the guest OS
VM is treated as a black box
Building block for Dynamic Data Center through business agility, cost reduction and increase in productivity
Load balancing VMs via policy

Live MigrationHow it Works
Create VM on target server
Run new VM on target; Delete VM on source
Copy memory pages from the source to the target via Ethernet
Final state transfer
Pause virtual machine
Move storage connectivity from source host to target host via Ethernet
Host 1
Host 2
Blue = Storage
Orange = Networking
Shared Storage

Cluster Shared VolumesMigration and Storage
NEW Cluster Shared Volumes (CSV) in Windows Server 2008 R2
Overview
CSV provides a single consistent file name space
All Windows Server 2008 R2 Server servers see the same storage
Benefits
Easy setup; Uses NTFS
No reformatting SANs
Create one big data store
No more drive letter problems
Existing tools just work
Highly recommended for live migration scenarios

Hot Add/Remove Storage
Overview
Benefits
Add and remove VHD and pass-through disks to a running VM without requiring a reboot
Hot-add/remove disk applies to VHDs and pass-through disks attached to the virtual SCSI controller
Enables storage growth in VMs without downtime
Enables additional datacenter backup scenarios
Enables new SQL/Exchange scenarios

Overview
Benefits
Allows live migration across different CPU versions within the same processor family (i.e. Intel-to-Intel and AMD-to-AMD)
Does NOT enable cross platform from Intel to AMD or vice versa
Configure compatibility on a per-VM basis
Abstracts the VM down to the lowest common denominator in terms of instruction sets available to the VM
Provides a great deal of migration flexibility within clusters
Enables migration across a broader range of Hyper-V host hardware
No specific hardware requirements needed
Processor Compatibility Mode

Improved Performance
Second Level Address Translation
TCP Offload support
Virtual Machine Queue (VMQ)
Jumbo Frame Support

Overview
Benefits
Uses new processor features to improve performance and reduce load on Windows Hypervisor
AMD: Nested Page Tables (NPT)
Intel: Extended Page Tables (EPT)
Improve memory management performance
Reduce in memory copies

Most improvement with large working sets (TS/SQL)
Second Level Address TranslationNew Processor Feature Support

10 GigE Ready
Networking Improvements
VM Chimney (TCP Offload Support)
Virtual Machine Queue
Jumbo Frame Support
TCP/IP traffic in a VM can be offloaded to a physical NIC on the host computer
Caution – Supports fixed number of offloaded connections – shared between all VMs
NIC can DMA packets directly into VM memory
Enables 6x larger payload per packet
Reduce CPU utilization of large file transfers

64 Logical Processor Support
Overview
Benefits
4x improvement over Hyper-V R1
Hyper-V can take advantage of larger scale-up systems with greater amount of compute resources
Up to 384 Running Virtual Machines & Support for up to 512 Virtual Processors (VPs) PER SERVER
384 single VP VMs OR
256 dual VP VMs (512 Virtual Processors) OR
128 quad VP VMs (512 Virtual Processors) OR
any combination so long as you're running up to 384 VMs and up to 512 Virtual Processors

Server Core Parking
Overview
Benefits
Scheduling virtual machines on a single server for density as opposed to dispersion
This allows “park/sleep” cores by putting them in deep C states
Significantly enhances Green IT by being able to reduce power required for CPUs

How is it different?
There is a difference between memory overcommit and overcommitting memory
We warned of the dangers of overcommitting memory
We pressed against the use of overcommit from a marketing perspective
Dynamic Memory allows for predictable, consistent performance even after overcommitting memory
Key is avoid the performance cliff which is possible with the VMware solution
The features VMware has does NOT provide significantly more scale than Hyper-V with DM does (despite what VMware will tell our customers)

How does VMware do it?
Memory Ballooning and Un-ballooning
Set VM memory, reservation, and limit
Will add and remove as necessary, between the reservation and limit
Memory Compression
Page Sharing
Optimized common memory pages
Affected by ASLR and SLAT
Hypervisor Memory Paging
Pages at the Hypervisor when physical memory is completely committed
All these (italicized) are only used after all physical memory is committed, which is not recommended by VMware or Microsoft!
