Lesson 8 VMotion

Lesson 8 Vmotion8-1 Vmotion Introduction

VMotion provides the ability to perform a live migration of

A VM from the one ESXi host to another ESXi host without service

Interruption. This is a no-downtime operation; network

Connections is not dropped and applications continue

running uninterrupted. In fact, the end users does not know

And is not aware, the VM has been migrated between

Physical ESXi hosts. When do vMotion to migrate a VM

From one ESXi host to another ESXi host, this means you also

Migrate the resource allocation-cpu and memory-

From one host to another.

according to the power state to divide , It is divided into Thermal Migration and cold migration

according to the function to divide , It is divided into host migration , Storage Migration , simultaneous migration with host storage

Note : Host storage migration only cold migration

Conditions of 8-2 Vmotion

In summary, there are three points:

1 shared storage

2 Assigning the Vmtion Vmkernel interface (requires a network bandwidth of gigabit and the same network configuration as the source and destination host)

3 requires the same CPU for different hosts

8-3 Storage vmtion Migration

We migrated the win2003-1 from local disk to the ISCSI SAN in the same host
