To specify the hypervisor to SBAdmin, create the file /storix/config/multibootfile (assuming /storix is your

Storix data d irector y). Wit hin this fi le, spec ify the path t o the Xen hyper visor. I n this c ase it would be as

follows.

/boot/xen-3.4.2. gz

You may now create a system backup.

System Backup of Citrix XenServer virtualized guests(domU)

Performin g a system backup of a Citri x XenServer virt ual machine (dom U) is done much in the sam e manner as

any other Linux s ystem. Refer to the SBAdmin User Guide for additional details.

Creating Boot Media

In order to perform s ystem recover y of a Citrix XenServe r virtual machine ( domU), you will need a SBAdmi n

system b ackup an d SBAdm in bo ot medi a. The b oot me dia is used to prov ide th e syst em you wish t o

recover wit h an environm ent and interfac e to perfo rm the recov ery. Boo t media t ype support ed for

performing re covery of domU is CDROM. Performing hard disk or network boot (PXE) of a domU is not

supported.

When creating CDROM boot media on an exiting domU it will be necessary to edit the following

configuration files so that the boot media will recognize the cdrom device.

The first step is to make a copy of device_info into the SBAdmin install directory, this will make changes

persist through software updates.

# cp /opt/storix /config/ device_info /storix/co nfig/device_ info

(Note, the destinat ion will be th e SBAdmin data dir ector y, chang e /storix/ in the desti nation

accordingly)

The next step is to ed it the /stor ix/ config/d evice _info file changing the foll owing li ne.

#cdrom:xvd:a-h:X en Virtu al Block Dev ice CDROM

cdro m:xvd:a-h:Xe n Virtua l Block Devi ce CDROM

Finally, for pa ravirt ualized gu ests, boot me dia must b e created using t he ISOLI NUX boot load er. The

following command will create CDROM boot medi a name d guest.is o in the /tm p direc tory. N ote, boot m edia

may only be made from the command line. It is not possible to do this from the Web or GUI interfaces.

# stmakeboot -t cdrom -S -b ISOLINUX -o /tmp/g uest.iso
