Implementing High Availability in
Hyper-V
This section covers the procedures for implementing High Availability in
Microsoft Hyper-V. This document only provides high level guidance. For
detailed instructions, please refer to

Implementing Hyper-V Host Clusters
For any successful Hyper-V Host Cluster deployment, careful consideration
must be given to the network and storage configurations to ensure that there
are no single points of failure and to ensure that there is sufficient bandwidth
for both network and storage traffic. For more information, see "Designing for
High Availability" on page 21.
This section discusses best practices for configuring a Hyper-V Host Cluster
and provides high-level steps to setup a Hyper-V Host cluster. For step-by-step
instructions on configuring a Hyper-V Host Cluster, refer Microsoft
documentation Hyper-V Step-by-Step Guide: Hyper-V and Failover Clustering
at http://technet.microsoft.com.
Preparing the Systems
1 Install Windows Server 2008 x64 Enterprise or DataCenter Editions on
your servers.
2 Make sure that the Hyper-V RTM upgrade patch (KB950050 from the
Microsoft website) has been applied on all servers.
3 Make sure that the 951308 QFE (KB951308 from the Microsoft website)
has been applied on all servers including systems that will run the
Failover
Cluster Management
console (cluadmin.msc). Make sure to download the
x64 version of the QFE.
