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

Agenda Live Migration

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

Agenda Live Migration using SMB

Live Migration with SMB Storage is not moved, just the running virtual machineLike 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

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

Setting up the share – Share Permissions

Agenda Live Migration and Clusters

Live Migration between clusters You can move a virtual machine between two clustersFollow 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 clusterJoin the virtual machine to the destination clusterVirtual machine never needs to be turned offHowever, it is not protected from hardware failure during the course of the migration.

Agenda Live Migration Security

Configuring Live Migration

Ensure Live Migration Networks are Secure Physically SecureIPSec / other encryption options

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

Credentials Understanding credential security

Understanding credential security Credentials

How this affects Hyper-V Live Migrate

Live Migrate How this affects Hyper-V Live Migrate

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

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 DirectoryMake it look like we are actually logged into the Hyper-V server that starts the live migrationPowerShell RemotingRemote Desktop

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 .

PowerShell Remoting with CredSSPOn the server: Enable-WSManCredSSP Server On the clientEnable-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>

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

Agenda Storage Migration

Storage Migration Move any part of a running virtual machine with no need to turn it offVHDsConfig files SnapshotsEtc…Perform storage upgrades with no downtimeRespond to I/O bottlenecks with no downtime

Agenda Importing virtual machines

Improvements to VM Import Basic building block of mobilityImprovements:Allow you to import a raw XML file Provide ability to “fix up” virtual machine during import

Demo Importing a VM

PowerShell PS C:\> Import-VM "C:\Users\benarm\Desktop\Import\76F5DA48-5181-4E75-83ED-FB2F65B56C8F.xml" -Copy -VhdSourcePath "C:\Users\benarm\Desktop\Import"Import-VM : Unable to import virtual machine due to configuration errors. Please use Compare-VM to repair the virtual machine.

PowerShell PS C:\> $ VMCompatReport = Compare-vm "C:\Users\benarm\Desktop\Import\76F5DA48-5181-4E75-83ED-FB2F65B56C8F.xml" -Copy -VhdSourcePath "C:\Users\benarm\Desktop\Import" PS C:\> $ VMCompatReport VM : Microsoft.HyperV.PowerShell.VirtualMachine OperationType : ImportVirtualMachine Destination : BENARM-EPSILON Path : C:\Users\benarm\Desktop\Import\76F5DA48-5181-4E75-83ED-FB2F65B56C8F.xml SnapshotPath : VhdDestinationPath : C:\Users\Public\Documents\Hyper-V\Virtual Hard Disks VhdSourcePath : C:\Users\benarm\Desktop\Import Incompatibilities : {33012, 14420}
