10. 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 …

11. 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

Before the migration
Check network / destination lun on Hyper-V Cluster
Check VM Health: no snapshot, restart the VM
Save Network configuration
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
Check connectivity, system and application logs, integration tools

… and its evolution

24. What’s new in Hyper-V in Windows Server 2012 R2
Feature or functionality
New or updated
Shared virtual hard disk
Hyper-V in Windows Server 2012 R2 Preview enables clustering virtual machines by using shared virtual hard disk (VHDX) files.
Resize virtual hard disk
Hyper-V storage has been updated to support resizing virtual hard disks while the virtual machine is running.
Storage Quality of Service
Storage QoS enables you to manage storage throughput for virtual hard disks that are accessed by your virtual machines
Live migrations
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
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

25. What’s new in SCVMM 2012 R2 (source: http://www.aidanfinn.com)
Feature or functionality
New or updated
3rd party Software Defined Networking
Is supported by the extensibility of the virtual switch.
Automatic Guest Activation
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.
Built-In NVGRE Gateway
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.
Clustering: Proactive Server Service Health Detection
The health of a destination host will be verified before moving a VM to another host.
Clustering: Protected Networks
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.
Compressed Live Migration
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.
Cross-Version Live Migration
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.
Dynamic Mode NIC Teaming
In addition to Hyper-V Port Mode and Address Hashing. Uses “flowlets” to give fine-grained inbound and outbound traffic.
Generation 2 VM
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).

26. What’s new in SCVMM 2012 R2 (source: http://www.aidanfinn.com)
Feature or functionality
New or updated
HNV Diagnostics
A new PoSH cmdlet enables an operator to diagnose VM connectivity in a VM Network without network access to that VM.
HNV: Dynamic Learning of CAs
Hyper-V Network Virtualization can learn the IPs of VM Network VMs. Enables guest DHCP and guest clustering in the VM Network.
HNV: NIC Teaming
Inbound and outbound traffic can traverse more than one team member in a NIC team for link aggregation.
HNV: NVGRE Task Offloads
A new type of physical NIC will offload NVGRE de- and encapsulation from the host processor.
HNV: Virtual Switch extensions
The HNV filter has been included in the Hyper-V Virtual Switch. This enables 3rd party extensions to work with HNV CAs and PAs.
Hyper-V Replica Extended Replication
You can configure a VM in Site A to replicate to Site B, and then replicate it from Site B to Site C.
Hyper-V Replica Finer Grained Interval controls
You can change the replication interval from the default 5 minutes to every 30 seconds or every 15 minutes.
IPAM
IP Address Management was extended in WS2012 R2 to do management of physical and virtual networking with built-in integration into SCVMM 2012 R2.
Live Resizing of VHDX
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.
Live Virtual Machine Cloning
You can clone a running virtual machine. Useful for testing and diagnostics.

27. What’s new in SCVMM 2012 R2 (source: http://www.aidanfinn.com)
Feature or functionality
New or updated
Remote Live Monitoring
Remote monitoring of VM network traffic made easier with Message Analyzer.
Shared VHDX
Up to 8 VMs can share a VHDX (on shared storage like CSV/SMB) to create guest clusters. Appears like a shared SAS drive.
SMB Live Migration
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 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!
SMB 3.0: Bandwidth controls
QoS just sees SMB 3.0. New filters for default, live migration, and virtual machine allow you to manage bandwidth over converged networks.
Network Diagnostics
New PowerShell tools for testing the networking of VMs, including Get-VMNetworkAdapter, Test-NetConnection, Test-VMNetworkAdapter, and Ping -P.
Virtual Machine Exports
You can export a VM with snapshots/checkpoints
Virtual Switch Extended Port ACLs
ACLs now include the socket port number.  You can now configure stateful rules that are unidirectional and provide a timeout parameter. Compatibility with Hyper-V Network Virtualization.
vRSS
Virtual Receive Side Scaling leverages DVMQ on the host NIC to enable a VM to use more than 1 vCPU to process traffic. Improves network scalability of a VM.
Windows Azure Pack
This was previously called Windows Azure Services for Windows Server. It allows companies (such as hosting companies) to provide a self-service portal (with additional cloud traits) for their cloud.

NIC Team Identify
Dynamic NIC Teaming optimizes utilization of a team on existing hardware, thereby maximizing ROI

30. NIC Teaming
Live Migration over NIC Team in Switch Independent Mode With Dynamic Load Balancing rocks !
all NICs are used 
no negative impact due to out of order packets since one single live migration sticks to a single team member

31. NIC Teaming and Converged Networks
Converged Fabrics tends to simplify data center management by consolidating all communication (Management, LiveMigration, Storage, Cluster) onto a single fabric for ease of management and better utilization of high availability features like Teaming
Two issues before:
Non optimized NIC Teaming
No QoS on Standard Hyper-V Virtual Switch

32. Converged Fabric with Windows Server 2012 R2 and SCVMM 2012 R2

51. Hyper-V and SCVMM: a case study and its evolution
Conclusion

52. 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
