Beyond virtualization
Basic server virtualization technology helps
achieve cost savings and operational efficiencies
Let’s go beyond basic
virtualization.
Create more dynamic
platforms to:
• Build private clouds.
• Create more flexible virtualization
solutions on site to support core line of
business applications and high
availability solutions.

Multitenant security and isolation
Hyper-V Extensible Switch
• New feature
• Handles network traffic between:
– Virtual machines
– The external network
– The host operating system
NIC = network adapter
• Layer-2 virtual interface
• Programmatically managed
• Extensible
11
Multitenant security and isolation
Private virtual LAN (PVLAN)
• Isolate virtual machines from other
virtual machines in your data center.
• Create community groups of virtual
machines that can exchange data
packets.
Example PVLAN:
‒ Primary VLAN ID is 2
‒ Secondary VLAN IDs are 4 and 5
12

Scale beyond VLANs with Hyper-V network virtualization
How network virtualization works:
• Two IP addresses for each virtual
machine
• General Routing Encapsulation (GRE)

• Policy management server
Problems solved:
• Removes VLAN constraints.
• Eliminates hierarchical IP address
assignment for virtual machines.
16
IP address rewrite
How IP address rewrite works
Benefits
• Each Customer Address (CA) is mapped to a unique
Provider Address (PA).
• Requires no upgrade of network adapters, switches,
or network appliances
• Information is sent in regular TCP/IP packets
on the wire.
• Can be deployed today without sacrificing
performance

• NIC Teaming Server Manager configuration UI
• Is designed to maintain connectivity if one switch
disconnects
• Can support up to 32 network adapters in a team
Example: SR-IOV

Live storage migration
• Move virtual hard disks (VHDs) attached to a
running virtual machine.
Benefits
• Manage storage in a cloud environment with
greater flexibility and control.
• Move storage with no downtime.
• Update physical storage available to a virtual
machine (such as SMB-based storage).
• Windows PowerShell cmdlets.
24

Hyper-V Move Vm Live
Reliably import virtual machines
Import Wizard
• Detects and fixes problems
• Doesn’t require the virtual machine to be exported
• Allows a virtual machine to be copied to a USB flash drive
• Moves virtual machines more easily and reliably
• Uses Windows PowerShell cmdlets for automation
Benefit
• A simpler, better way to import or copy virtual machines.
26
Merge snapshots while the virtual machine is running
Snapshot features
• Snapshot data are stored in .avhd files
• You can merge the .avhd disk into the parent
while the virtual machine continues to run
Benefit
• Update parent virtual hard disks while the
virtual machine is still running
• I/O is suspended to a small range while data
in the range is processed
• At completion, online merge fixes merged
disks and closes files.
