Introduction
This post on Hyper-V Live Migration is a two-part series.
In this first part, we will discuss the following:
- What is Live Migration
- Types of Live Migration
- How each migration works
In the second part of the series, we will look at the Best Practices, Troubleshooting steps and Tips for Live Migration.
What is Hyper-V Live Migration?
Hyper-V Live Migration is the possibility to migrate any of your Virtual Machines between your physical Hyper-V Servers.
Hyper-V Live Migration works to a Hyper-V Server Standalone or a Hyper-V Cluster Node without any downtime (only in some cases) over the network.
One of the best benefits of Live Migration is the flexibility that administrators have and allowing them to create highly available and fault-tolerant systems.
Hyper-V Live Migration is possible by manual (Standalone Hyper-V / Hyper-V Failover Cluster ) or automatic (only Hyper-V Failover Cluster) method to migrate any VMs from your Hyper-V node to another node. Not only VMs between Hyper-V but also the location of your VM to a different Storage/Disk location.
To perform these migrations, you can use Hyper-V Manager (for manual migration) or Hyper-V Failover Cluster Manager (manual and automatic).
Automatic Hyper-V Live Migration is triggered when your Hyper-V Failover Cluster has a node failure (or isolation). In this case, all Virtual Machines in the failure node will automatically migrate to another node in the Cluster, using the “The Best Possible Node” option.
Hyper-V Live Migration consists of four types of migrations:
- Shared-Nothing Live Migration
- Live Migration
- Quick Migration
- Storage Live Migration
