• Aggiungere un cdrom

<disk type="file" device="cdrom">
    <driver name="file"/>
    <source file="/var/lib/xen/images/rhn-satellite-5.0.1-11-redhat-linux-as-i386-4-embedded-oracle.iso"/>
    <target dev="hdc"/>
    <readonly/>
</disk>

• Boot da cdrom

<boot dev='cdrom'/>

• Boot da hard disk

<boot dev='hd'/>

• Per creare una immagine disco da 80 gb:

sudo dd if=/dev/zero of=emip-sdb.img oflag=direct bs=1M seek=80000 count=1
