2. Mobility Core to Private Cloud
Virtualization is the basis of a Microsoft private cloud
Virtual machine mobility is key an efficient and responsive private cloud deployment

3. Agenda
Live Migration

4. Live Migration without Infrastructure
You can even live migrate virtual machines between two Hyper-V servers with no shared infrastructure
Need to be in the same domain
Entire virtual machine moved (VHDs + running state) with no downtime

16. Live Migration using SMB
Agenda
Live Migration using SMB

17. Live Migration with SMB
Storage is not moved, just the running virtual machine
Like live migration in a cluster, without high availability
Requires SMB 3.0
VIR306: Hyper-V over SMB2: Remote File Storage Support in Windows Server 2012 Hyper-V

18. Setting up SMB for Live Migration
There are a couple of steps involved in getting this right
Both users and computers need access to the share

19. Setting up the share – Share Permissions

20. Setting up the share – Share Permissions

21. Setting up the share – Share Permissions

Agenda
Live Migration and Clusters

30. Live Migration Improvements
Live Migration in Windows Server 2008 R2 is great
but how to make it better?

31. Live Migration Improvements
Live Migration in Windows Server 2008 R2 is great
but how to make it better?
Faster
Concurrent live migration
Deeper integration into clustering
Etc…
WSV324: Building a Highly Available Failover Cluster Solution with Windows Server 2012 from the Ground UP

32. Live Migration between clusters
You can move a virtual machine between two clusters
Follow these steps:
Remove the virtual machine from the source cluster
Use Hyper-V Manager to live migrate the virtual machine to a node in the destination cluster
Join the virtual machine to the destination cluster
Virtual machine never needs to be turned off
However, it is not protected from hardware failure during the course of the migration.

34. Live Migration Security
Agenda
Live Migration Security

35. Configuring Live Migration

36. Ensure Live Migration Networks are Secure
Physically Secure
IPSec / other encryption options

37. Managing security and authentication
This gets very complicated once more than two computers are involved
And sometimes even when there are only two computers involved

38. Understanding credential security

39. Understanding credential security

40. Understanding credential security

41. How this affects Hyper-V

42. How this affects Hyper-V

43. How this affects Hyper-V
Live Migrate a VM to me
Live Migrate

44. How to make this work? Two options:
Allow user credentials to be shared between the Hyper-V servers – just for the purposes of live migration
Enable “Constrained Delegation” in Active Directory
Make it look like we are actually logged into the Hyper-V server that starts the live migration
PowerShell Remoting
Remote Desktop

45. Enabling Constrained Delegation
On the domain controller, open Active Directory Users and Computers.
In the console tree, under DomainName, click Computers.
Right-click the computer running Hyper-V, and then click Properties.
On the Delegation tab, click Trust this computer for delegation to specified services only.
Click either Use any authentication protocol or Use Kerberos only.
Click Add, and then click Users and Computers.
Type the name of the other computer running Hyper-V, and then click OK.
From the list of available services, select Microsoft Virtual System Migration Service and CIFS and then click OK.

52. PowerShell Remoting with CredSSP
On the server:
Enable-WSManCredSSP Server
On the client
Enable-WSManCredSSP Client –DelegateComputer <FQDN of the server>
Establish the session:
New-PSSession <FQDN of the Server> -Authentication CredSSP -Credential <User> | Enter-PSSession
Or just run a command:
ICM <FQDN of the Server> {<command to run>} -Authentication CredSSP -Credential <User>

53. Remote Desktop
Hopefully I do not need to tell you how to use this 

54. Agenda
