Instructions on how to deploy a high availability KVM cluster based on CentOS 6.x

• Deploy Centos (minimal)
• Enjoy with the networking scripts.
• Disable SELINUX
• Install EPEL meta-pkg:

rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm

• Install basic pkgs (for me):

yum -y install vim tmux lsof strace

• Update:

yum update

• Enjoy with multipathd+storage
• Install the clusterware suite:

yum groupinstall "High Availability" "Resilient Storage"

• In the “master” node, install the admin suite:

yum groupinstall "High Availability Management"
