Live Migration is a planned failover solution What is Live Migration? Move a running virtual machine from one host to another host with no perceived downtime for the VM VM is not aware of the migration Maintain TCP connections of the guest OS Building block for Dynamic Data Center through business agility, cost reduction and increase in productivity VM is treated as a black box How is it different from Quick Migration? VM is saved and restored on destination Results in downtime for applications/workloads running inside VMs Both leverage same storage infrastructure – easy to move from QM to LM Live Migration is a planned failover solution

Key scenario 1: Host servicing Live Migrate VMs from source to destination Service Source – patching or hardware servicing, no downtime seen by VMs on destination Live Migrate VMs from back from destination to source No workload downtime during maintenance window

Key scenario 2: Load Balancing SCVMM 2008 R2 driven by PRO (Performance Resource Optimization) can dynamically live migrate VMs to meet changing load

Key scenario 3: Green IT – Power Management During business hours, both servers are in use

Key scenario 3: Green IT – Power Management During off-peak or non-business hours, number of clients go down

Key scenario 3: Green IT – Power Management Following day as business starts, load/demand go up, VMs are live migrated back

How Does Live Migration Work? Prerequisites: Source and Destination computers running WS08 R2 Source and destination nodes must be part of a Failover Cluster Files used by the VM must be located on shared storage Failover Cluster Source Node Destination Node .BIN .VSV .XML .VHD Storage

How Does Live Migration Work? Phase 1: Setup Create TCP connection between source and destination nodes Transfer VM configuration data to destination node Create a new VM on the destination node Configuration Data Source Node Destination Node .BIN .VSV .XML .VHD Network Storage

How Does Live Migration Work? Phase 2: Memory transfer Transfer the content of the VMs memory to the destination node Track pages modified by the VM, retransfer these pages Pause the VM before the final transfer pass Memory Content Source Node Destination Node .BIN .VSV .XML .VHD Network Storage

How Does Live Migration Work? Phase 3: State transfer and VM restore Save register and device state of VM on source node Transfer running state and storage ownership to destination node Start running VM on destination node Cleanup VM on source node Running State Source Node Destination Node .BIN .VSV .XML .VHD Network Storage

Storage Management During Live Migration Live Migration requires VMs to use shared storage SAN LUNs managed by the Failover Clustering service Traditionally, each VM needs its own LUN Volumes cannot be concurrently mounted on multiple nodes SAN .BIN .VSV .XML .VHD .BIN .VSV .XML .VHD .BIN .VSV .XML .VHD

Storage Management During Live Migration The migration of a VM with a dedicated LUN requires that the ownership of the LUN is moved from the source to the destination node Time-consuming, requires the volumes on the LUN to be offlined on the source node and onlined on the destination node Is part of the blackout period SAN .BIN .VSV .XML .VHD .BIN .VSV .XML .VHD .BIN .VSV .XML .VHD

Cluster Shared Volumes (CSV) New feature of Failover Clustering in Windows Server 2008 R2 Single consistent namespace for the volumes on all nodes %SystemDrive%\ClusterStorage\VolumeX SAN .BIN .VSV .XML .VHD .BIN .VSV .XML .VHD .BIN .VSV .XML .VHD

CSV and Live Migration Moving the files of a VM during a migration becomes as simple as closing the files on the source node and opening the files on the destination node Additionally, CSV significantly simplifies the administration of the SAN SAN .BIN .VSV .XML .VHD .BIN .VSV .XML .VHD .BIN .VSV .XML .VHD

Demo Environment Overview DEMO-NODE1 DEMO-NODE2 Gigabit Switch Orange: DC Grey: HOST-001 (Not domain joined) Internet

Live Migration via CSV: Step 1 Install WS08 R2 on all systems Add Hyper-V Role Install WS08R2 VM on Storage Server Will act as DC for the demo Domain required for failover clustering Add failover clustering role on cluster nodes Run DCPromo on VM Join machines to domain Optional: Add DHCP role

Live Migration via CSV: Step 2 iSCSI Target Configuration Microsoft iSCSI Software Target Included in Windows Storage Server – now available for MSDN/TechNet subscribers! Alternative iSCSI Targets Starwind iSCSI Target SANFly Create Volumes 1 GB for quorum Remainder for CSV Ensure bindings are correct!

Live Migration via CSV: Step 3 Configure Networking on nodes Create Hyper-V External Virtual Network Assign Static IP to Virtual NIC Launch iSCSI Control Panel Start -> Administrative Tools -> iSCSI Initiator Log in to iSCSI target

Live Migration via CSV: Step 4 Create iSCSI Target for cluster Use IQN (iSCSI Qualified Name) Add both cluster nodes Assign volumes to target From Node 1, open Disk Management and online / format disks Disk 1: Letter Q, Label: Quorum Disk 2: Letter S, Label: CSV Ensure that “Add this connection to the list of Favorite Targets” is set!

Live Migration via CSV: Step 5 Open Failover Cluster Manager Form Cluster Cluster Validation Wizard Enable CSV Add Disk to CSV

Live Migration via CSV: Step 6 Create VM on CSV volume (c:\clustervolume\volume1) Add as cluster resource Power on VM Live Migrate!

Changes at WS08R2 RTM Need multiple NIC’s if using iSCSI NIC 1: Normal Network Traffic NIC 2: iSCSI Traffic NIC 3: CSV Traffic
