Creating and launching a kernel-based virtual machine (KVM) host
KVM is available as part of Red Hat Enterprise Linux (RHEL) and SUSE Linux Enterprise Server (SLES). Management for RHEL KVM is provided through separate RPMs that can be downloaded into the standard RHEL installation. Management for SLES KVM is provided through SLES or through separate RPMs that can be downloaded into the standard SLES installation.
The virt-manager tool provides a very simple, easy-to-use and intuitive GUI interface for all virtual machine operations, along with virt-viewer. A command line alternative, virsh, also provides a shell that can be used to create and manage virtual machines using a rich set of commands. The features provided by these tools include taking snapshots of virtual machines, creating virtual networks and live migration of virtual machines to another KVM host.
Once you have configured the required hardware setup:
Install KVM on the target systems.
Create and launch the required KVM virtual machines.
Proceed to install the required SFHA product on the guest or host:
