Breaking old ideas
Hyper-V is right only for Branch Offices
Hyper-V cannot be compare to VMware in terms of
features
Hyper-V supports a very limited range of Guest OS
Hyper-V does not support high-performance network
…
Breaking old ideas
Gartner:
“ Microsoft has improved its server virtualization products to the
point that IT leaders should assess their VMware investments and
consider whether Microsoft makes sense. Compare acquisition
costs, ease of management and functionality for the two vendors
and take advantage of their competitiveness.” 1

Success story: Migration to Hyper-V
Challenge
Migration of 180 Virtual Machines
Constraints
OS: Windows 2000 to 2008R2, Linux, Appliances, Netware…
No virtual machines is domain joined
As usual, migration out of business hours, limited downtime
Toolbox: SCVMM 2012 SP1
Legacy VMware
Cluster
Hyper-V Cluster
Process
During the
migration
• Remove VMware tools and VMware network card
• Move virtual machine using VMM / Powershell scripts
• Configure network and restart system
After the
migration
After secure
time
• Check connectivity, system and application logs, integration tools
• Proceed application check
• Remove virtual machine on VMware infrastructure (V2V is non-destructive operation)
Application owner involment
Before the
migration
• Check network / destination lun on Hyper-V Cluster
• Check VM Health: no snapshot, restart the VM
• Save Network configuration
Tips to sleep at night: Networking
Save network configuration
C:\> Netsh dump > network.cfg
Save network configuration
C:\> Netsh exec network.cfg
Remove ghost NIC
C:\> set devmgr_show_nonpresent_devices=1
C:\> start devmgmt.msc
Tips to sleep at night: Old Windows

A case study …
… and its evolution
Feature or functionality
Shared virtual hard disk
Resize virtual hard disk
Storage Quality of Service
Live migrations
Virtual machine generation
New or updated
Hyper-V in Windows Server 2012 R2 Preview enables clustering virtual machines by using
shared virtual hard disk (VHDX) files.
Hyper-V storage has been updated to support resizing virtual hard disks while the virtual
machine is running.
Storage QoS enables you to manage storage throughput for virtual hard disks that are
accessed by your virtual machines
Hyper-V live migration has been updated to allow the administrator to select the optimal
performance options when moving virtual machines to a different server.
Virtual machine generation determines the virtual hardware and functionality that is
presented to the virtual machine:
•
Secure Boot (enabled by default)
•
Boot from a SCSI virtual hard disk
•
Boot from a SCSI virtual DVD
•
PXE boot by using a standard network adapter
•
UEFI firmware support
Feature or functionality
3rd party Software Defined
Networking
Automatic Guest Activation
Built-In NVGRE Gateway
Clustering: Proactive Server
Service Health Detection
Clustering: Protected Networks
Compressed Live Migration
Cross-Version Live Migration
Dynamic Mode NIC Teaming
Generation 2 VM
New or updated
Is supported by the extensibility of the virtual switch.
Customers running WS2012 R2 Datacenter can automatically activate their WS2012 R2 guests
without using KMS. Works with OEM and volume licenses. Great for multi-tenant clouds.
A multi-tenant aware NVGRE gateway role is available in WS2012 R2. Offers site-site VPN,
NAT for Internet access, and VM Network to physical network gateway.
The health of a destination host will be verified before moving a VM to another host.
Virtual NICs are marked as being on protected networks by default. If a virtual NICs’ virtual
switch becomes disconnected then the cluster will Live Migrate that VM to another host with
a healthy identical virtual switch.
Using only idle CPU resources on the host, Hyper-V can compress Live Migration to make it
quicker. Could provide up to 2x migrations on 1 GbE networks.
You can perform a Live Migration from WS2012 to WS2012 R2. This is one-way, and enables
zero-downtime upgrades from a WS2012 host/cluster to a WS2012 R2 host/cluster.
In addition to Hyper-V Port Mode and Address Hashing. Uses “flowlets” to give fine-grained
inbound and outbound traffic.
A G2 virtual machine is a VM with no legacy “hardware”. It uses UEFI boot, has no emulated
devices, boots from SCSI, and can PXE boot from synthetic NIC. You cannot convert from G1
VM (UEFI I am guessing).
Feature or functionality
HNV Diagnostics
HNV: Dynamic Learning of CAs
HNV: NIC Teaming
HNV: NVGRE Task Offloads
HNV: Virtual Switch extensions
Hyper-V Replica Extended
Replication
Hyper-V Replica Finer Grained
Interval controls
IPAM
Live Resizing of VHDX
Live Virtual Machine Cloning
New or updated
A new PoSH cmdlet enables an operator to diagnose VM connectivity in a VM Network
without network access to that VM.
Hyper-V Network Virtualization can learn the IPs of VM Network VMs. Enables guest DHCP
and guest clustering in the VM Network.
Inbound and outbound traffic can traverse more than one team member in a NIC team for
link aggregation.
A new type of physical NIC will offload NVGRE de- and encapsulation from the host processor.
The HNV filter has been included in the Hyper-V Virtual Switch. This enables 3rd party
extensions to work with HNV CAs and PAs.
You can configure a VM in Site A to replicate to Site B, and then replicate it from Site B to Site
C.
You can change the replication interval from the default 5 minutes to every 30 seconds or
every 15 minutes.
IP Address Management was extended in WS2012 R2 to do management of physical and
virtual networking with built-in integration into SCVMM 2012 R2.
You can expand or shrink (if there’s un-partitioned space) a VHDX attached to a running VM.
It must be SCSI attached. This applies to Windows and Linux.
You can clone a running virtual machine. Useful for testing and diagnostics.
Feature or functionality
Remote Live Monitoring
New or updated
Remote monitoring of VM network traffic made easier with Message Analyzer.
Up to 8 VMs can share a VHDX (on shared storage like CSV/SMB) to create guest clusters.
Appears like a shared SAS drive.
This feature uses SMB to perform Live Migration over 10 GbE or faster networks. It uses SMB
Multichannel if there are multiple Live Migration networks. SMB Direct is used if RDMA is
SMB Live Migration
available. SMB Multichannel gives the fastest VM movement possible, and SMB Direct
offloads the work from the CPU. Now moving that 1 TB RAM VM doesn’t seem so scary!
QoS just sees SMB 3.0. New filters for default, live migration, and virtual machine allow you to
SMB 3.0: Bandwidth controls
manage bandwidth over converged networks.
New PowerShell tools for testing the networking of VMs, including Get-VMNetworkAdapter,
Network Diagnostics
Test-NetConnection, Test-VMNetworkAdapter, and Ping -P.
Virtual Machine Exports
You can export a VM with snapshots/checkpoints
ACLs now include the socket port number. You can now configure stateful rules that are
Virtual Switch Extended Port ACLs unidirectional and provide a timeout parameter. Compatibility with Hyper-V Network
Virtualization.
Virtual Receive Side Scaling leverages DVMQ on the host NIC to enable a VM to use more
vRSS
than 1 vCPU to process traffic. Improves network scalability of a VM.
This was previously called Windows Azure Services for Windows Server. It allows companies
Windows Azure Pack
(such as hosting companies) to provide a self-service portal (with additional cloud traits) for
their cloud.

Hyper-V and SCVMM: a case study and its evolution
Conclusion
Conclusion
Hyper-V 2012 R2 and SCVMM 2012 R2 do represent a
MAJOR improvement in the Microsoft virtualization
technologies portfolio
Old ideas must be forgotten and Microsoft technologies
are certainly to consider when implementing a new
environment, including for mission-critical systems
Hyper-V Network Virtualization is a little bit complex to
understand but it’s certainly worthwhile: HNV is very
powerful and ready for deployment in your datacenters
