For the context: type='volume' allows user to use disks from storage pool without caring about details how the pool was defined. For example with the pool 'pool1' deined like: <pool type="dir"> <name>pool1</name> <target> <path>/var/vm_pool/</path> </target> </pool> The following disk definitions are equivalent: <disk type='file' device='disk'> <source file='/var/vm_pool/machine1.qcow2'/> ... </disk> and <disk type='volume' device='disk'> <source pool='pool1' volume='machine1.qcow2'/> ... </disk>

The disk definition is wrong: <disk type='volume' device='disk'> <driver name='qemu' type='raw'/> <target dev='hda' bus='ide'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> There is no <source> element here. You need to add something like: <source pool='some_pool' volume='some_volume.qcow2' />
Hi Tomas I'm reviewing the doc text and it is not clear to me what you mean by "In this case the disk is described as a storage pool/volume pair." Also, is there any impact on documentation? i.e. is there something that must be manually configure in order for this to work? Thanks Emma

This tells how the disk is defined in libvirt XML of the VM on the source KVM machine. > Also, is there any impact on documentation? i.e. is there something that > must be manually configure in order for this to work? No.

I believe this is too detailed for the Release Notes which describes what the fix/enhancement does, and not how that was achieved. > > Also, is there any impact on documentation? i.e. is there something that > > must be manually configure in order for this to work? > > No.
