The XML for quite a longish backing chain is shown below: <disk type='network' device='disk'> <driver name='qemu' type='qcow2'/> <source protocol='nbd' name='bar'> <host transport='unix' socket='/var/run/nbdsock'/> </source> <backingStore type='block' index='1'> <format type='qcow2'/> <source dev='/dev/HostVG/QEMUGuest1'/> <backingStore type='file' index='2'> <format type='qcow2'/> <source file='/tmp/image2.qcow'/> <backingStore type='file' index='3'> <format type='qcow2'/> <source file='/tmp/image3.qcow'/> <backingStore type='file' index='4'> <format type='qcow2'/> <source file='/tmp/image4.qcow'/> <backingStore type='file' index='5'> <format type='qcow2'/> <source file='/tmp/image5.qcow'/> <backingStore type='file' index='6'> <format type='raw'/> <source file='/tmp/Fedora-17-x86_64-Live-KDE.iso'/> <backingStore/> </backingStore> </backingStore> </backingStore> </backingStore> </backingStore> </backingStore> <target dev='vdb' bus='virtio'/> </disk> Various disk types and formats can be mixed in one chain. The <backingStore/> empty element marks the end of the backing chain and it is there mostly for future support of parsing the chain provided by a user. If it's missing, we are supposed to probe for the rest of the chain ourselves, otherwise complete chain was provided by the user. The index attributes of backingStore elements can be used to unambiguously identify a specific part of the image chain. Signed-off-by: Jiri Denemark <jdenemar@redhat.com> |
