4. 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

5. 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

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

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

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

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

10. 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

11. 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

12. 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

13. 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

Network Storage

14. 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

15. 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

17. 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

Dell Optiplex 745
Quad Core, 8 GB RAM
Storage:
Dell SC1430
3 x 160 GB Disk, RAID
Microsoft iSCSI Target
Networking:
Multiple Gigabit Interfaces on server, single on node
Other:
All running Windows Server 2008 R2
Best Practices:
Cluster Nodes:
Hardware with Windows Logo + Failover Cluster Configuration Program (FCCP)
Storage:
Storage with Windows Logo + FCCP
Networking:
Multiple Gigabit Interfaces
CSV uses separate network
Other:
All running Windows Server 2008 R2

Grey: HOST-001
(Not domain joined)
Internet

22. Live Migration via CSV: Step 1
Install WS08 R2 on all systems
