Product Description
Xen is an open-source paravirtualization technology that provides aplatform for running multiple operating systems on one physicalhardware resource, while providing close to native performance. Xensupports several operating systems–Linux, FreeBSD, Windows, and NetBSD.It enables you to easily test, deploy and run your software andservices on multiple operating systems with resource isolation andgreat performance.In this book we explore and use the open-source version of Xen.
- Getting started with virtualization and Xen
- Installing Xen from pre-built packages using yum
- Installing and compile Xen from source
- Running guest domains under Xen:
- Create Ubuntu guest domain using debootstrap
- Create NetBSD domain using install image
- Create a Centos image using Qemu
- Create Slackware domain using domU image from jailtime
- Managing remote Xen instances using:
- Xen manager (xm)
- XenMan
- Virt-manager
- Configuring Xen for networking
- Connecting domains using:
- Bridged networking–uses network bridge and hardware MAC addresses
- Routed networking–uses Dom0 for all traffic
- Implementing storage solutions for guest domains:
- Using Files–file based; perfect for testing
- Using Network File Systems (NFS)–works with remote NFS server
- Using Logical Volume Management (LVM)–for enterprise-grade storage
- Securing your domain by encrypting root file systems
- Plain device mapper-based encryption
- Key-based device mapper encryption using LUKS
- Migrating live domains from one server to another
- Saving and restoring a domain
- Trends and forthcoming advances in the Xen world:
- libvirt to simplify access to virtualization domains in a vendor/hypervisor-independent way
- VMcasting for transferring virtual machine images from the server to the client using RSS 2.0
