There are a few cases where we are using either WHEN_ACTIVE

disk-mirror-old has different output file for the active and

hand, both output files for disk-backing-chains-noindex are
identical, so it makes sense to only keep around one and remove

After commits e2087c29 and ec0793de older GCC started act very smart and
complain about potentially uninitialized variable, which existed prior
to these patches + even if the affected vars were left uninitialized the
function responsible for filling them in would have failed with NULL
being returned which the caller has always handled carefully.
Although GCC complained only about a single variable, let's initialize
all of them so as to prevent any further potential breakages.

Add <controller type='scsi' model handling for virtio transitional
devices. Ex:

  <controller type='scsi' model='virtio-transitional'/>

* "virtio-transitional" maps to qemu "virtio-scsi-pci-transitional"
* "virtio-non-transitional" maps to qemu "virtio-scsi-non-transitional"

The naming here doesn't match the pre-existing model=virtio-scsi.
The prescence of '-scsi' there seems kind of redundant as we have
type='scsi' already, so I decided to follow the pattern of other
patches and use virtio-transitional etc.

qemu vhost-scsi devices map to XML roughly like:

To support vhost-scsi-pci-{non-}traditional in qemu, we
need to to extend the SCSI Host hostdev XML to handle
model= value. This matches the XML model= format used
for mediated devices. This is just the domain_conf bits
and some XML test cases.

Use of virtio-X naming here does not match the hostdev
protocol=vhost nor does it match the qemu vhost-X device
naming, however it's more consistent with all other
model= names in this area, and also matches the
inconsistency of <vsock> devices which use model=virtio
but map to vhost-vsock on the qemu commandline

serves other purposes too like determing what target=

devices will complicate apps lives, and it isn't a clean
mapping anyways. So let's bite the bullet and add a new

This function is called when a domain is starting up (in qemu
driver that is when qemu cmd line is generated). It is used to
translate <disk type='volume'/> to something usable by filling in
virStorageSource (e.g. fetching disk path, or some connection URI
for a network FS). But some of these info are not stored in
status XML and thus the function is called on
qemuProcessReconnect too to reconstruct runtime data. But this
poses a problem because after the first run the mode is set to
'direct', but in the second run this triggers a failure because
mode is valid only for 'iscsi' volumes and not 'iscsi-direct'
ones.
