Hyper-V Live Migration

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

Scenario 2: load balancing

R2

SCVMM 2008 R2 driven by PRO (Performance Resource Optimization) can dynamically live migrate VM’s to

meet changing load

Live Migration: How It Works

1. Create VM on target server

Host 1 Host 2Blue = StorageYellow = Networking

Shared Storage

3. Final state transfera) Pause virtual machineb) Move storage connectivity from source host to target host via Ethernet

4. Run new VM on target; Delete VM on source

2. Copy memory pages from the source to the target via Ethernet

Storage Model with Failover Clustering in Windows Server 2008

Failover Clustering implemented a “shared nothing” storage model for the last decadeEach Disk is owned by a single node at any one time, and only that node can perform I/O to it

Shared Storage

Only one node accesses a LUN at a

time

SAN

Migration & StorageWindows Server 2008 R2 Hyper-V

NEW Cluster Shared Volume (CSV)CSV provides a single consistent file name spaceAll Windows Server 2008 R2 servers see the same storage

Easy setup; Uses NTFSNo reformatting SANsCreate one big data storeNo more drive letter problemsExisting tools just work

Cluster Shared Volumes

All servers “see” the same storage

Node Fault Tolerance

Volume relocates to a healthy node

Brief queuing of I/O while volume ownership is

changed

VHD

Coordination Node

VM running on Node 2 is unaffected

SAN

I/O Connectivity Fault Tolerance

VM running on Node 2 is unaffected

VHD

I/O Redirected via network

VM’s can then be Live Migrated to another node with zero downtime

Storage Improvements and new features

Hot Add of VM storage

Ability to add/remove storage to running VMs

Reduces downtime and provides flexibility to admins to add/remove storage as needed

Admin needs to add storage space to VMHe would need to stop the VM to do thisWith VMM R2 and Win2k8 R2

Admin can create additional storage and add it to running VM

Admin needs to backup a VMCan create VSS snapshot of his running OSUse the new disk as destination of snapshotRemove the disk from running VM

New Processor features

64 Logical Processor Support

Overview

4x improvement over Hyper-V V1

Hyper-V can take advantage of larger scale-up systems with greater amount of compute resources

Up to 384 Running Virtual Machines & Support for up to 512 Virtual Processors (VPs) PER SERVER

384 single VP VMs OR

256 dual VP VMs (512 Virtual Processors) OR

128 quad VP VMs (512 Virtual Processors) OR

any combination so long as you're running up to 384 VMs and up to 512 Virtual Processors

Processor Compatibility Mode

OverviewAllows live migration across different CPU versions within the same processor family (i.e. Intel-to-Intel and AMD-to-AMD).

Does NOT enable cross platform from Intel to AMD or vice versa.

Configure compatibility on a per-VM basis.

Abstracts the VM down to the lowest common denominator in terms of instruction sets available to the VM.

• Benefits• Greater flexibility within

clusters• Enables migration across

a broader ranger of Hyper-V host hardware

How does Compatibility work?

When a VM is started the hypervisor exposes guest visible processor featuresWith Processor Compatibility Enabled processor features are “hidden” from the VM

CPUID will not return presence of hidden features

Hardware:4 Generations of Intel VT Processors4 Node Cluster using 1 Gb/E iSCSI

Test:Created script to continuously Live Migrate VMs every 15 seconds

Result: 20,000+ Migrations in a week!

Windows Server 2008 R2Core Parking

OverviewScheduling virtual machines on a single server for density as opposed to dispersionThis allows “park/sleep” cores by putting them in deep C states

Hyper-V Networking

Hyper-V R2 Networking10 Gb/E Ready

Chimney Support (10Gb/E)TCP/IP traffic in a VM can be offloaded to a physical NIC on the host computer.

Reduce CPU burden; Live Migration is fully supported with Full TCP Offload

Works best with long-lived connections with large data transfers

VMQ Support (10Gb/E)NIC can DMA packets directly into VM memory

Host no longer has device DMA data in its own buffer resulting in a shorter path length for I/O (performance gain)

Jumbo Frame Support (1 Gb/E & 10 Gb/E)Enables 6x larger payload per packet

Improves throughput

Reduce CPU utilization of large file transfers
