The Veritas InfoScale Solutions can be used in Kernel-based Virtual Machine-based virtualization environments to provide advanced storage management, mission-critical clustering, fail-over, and migration capabilities.
Linux Kernel-based Virtual Machine (KVM) is released by Red Hat Enterprise Linux (RHEL) and SUSE Linux Enterprise Server (SLES) as a full virtualization solution. KVM differs from other popular alternatives like Xen and VMware in terms of operation, performance and flexibility. KVM comes as a kernel module, with a set of user space utilities to create and manage virtual machines (VM).
Kernel-based Virtual Machine technology includes the following:
A full virtualization solution for Linux on AMD64 & Intel 64 hardware.
Each KVM virtualized guest or "VM guest" is run as a single Linux process.
A hypervisor-independent virtualization API, libvirt, which provides a common generic and stable layer to securely manage VM guests on a host.
A command line tool virsh used to manage the VM guests.
A graphical user interface (GUI) virt-manager for managing the VM guests.
Configuration of each VM guest stored in an XML file.
This guide illustrates some reference configurations which can be customized to fit most implementations. An assumption is made that the reader understands the Linux operating system, including its architecture, as well as how to configure and manage KVM virtual machines using the management software already provided by Linux. There is also an expectation that the user is familiar with the basic Veritas InfoScale Solutions software and is well versed with its administration and management utilities. Additional details regarding Linux and Veritas InfoScale Solutions software are available in the Additional documentation section.
