Xen Recovery Guide Version 8.
SBAdmin and Xen Recovery Guide The purpose of this guide is to provide the steps necessary to use SBAdmin in a Xen environment and to define what aspects of system recovery are and are not supported when using SBAdmin in a Xen environment. This guide does not include all the features and options available with SBAdmin, but is intended to be used as an addendum to the SBAdmin User Guide.
To specify the hypervisor to SBAdmin, create the file /storix/config/multibootfile (assuming /storix is your Storix data directory). Within this file, specify the path to the Xen hypervisor. In this case it would be as follows. /boot/xen-3.0-i386.gz You may now create a system backup and boot media. Full System Backup and Recovery of a Paravirtualized domU In a paravirtualized Xen environment, the Xen hypervisor is responsible for loading a modified kernel.
stmakeboot -t initrd-install -o /storix/temp/initrd-domUinstall.img After the image has been created on the domU, you will copy it to the domU's boot directory, as defined by the configuration file on dom0. You may also need to copy the running domU kernel to dom0 as well. CDROM Boot Media If your Xen environment allows you to boot from an ISO image, or using a network path. You may create a CDROM ISO image for system recovery.
# /etc/xen/sample # Sample Xen configuration file for SBAdmin boot media name = "storix" # Xen name kernel = "/boot/vmlinuz-2.6.19-4-generic" # domU kernel ramdisk = "/boot/initrd-domUinstall.
Full System Backup and Recovery of a Full-virtualized domU In a fully virtualized environment the guest operating system is running its own un-modified kernel. Therefore, there are no special considerations and should be treated just as any other Linux system. You should refer to the SBAdmin User Guide and SBAdmin Linux System Installation Guide for further details. Storix System Backup Administrator 6 SBAdmin Xen User Guide Copyright © 2014 Storix, Inc.
