887dd3625b storage: fix RNG validation of gluster via netfs
While trying to compare netfs against my new gluster pool, I
discovered two things:

virt-xml-validate chokes on valid xml produced by 'virsh pool-dumpxml'
[yet another reason that ALL patches that add new xml should be adding
corresponding tests]

When using glusterfs FUSE mounts, you cannot access a subdirectory
of a gluster volume.  The recommended workaround in the gluster
community is to mount the volume to an intermediate location, then
bind-mount the desired subdirectory to the final location.  Maybe
we should teach libvirt to do bind-mounting, but for now I chose to
just document the limitation.

* docs/storage.html.in: Improve documentation.
* docs/schemas/storagepool.rng (sourcefmtnetfs): Allow all
formats, and drop redundant info-vendor.
* tests/storagepoolxml2xmltest.c (mymain): New test.
* tests/storagepoolxml2xmlin/pool-netfs-gluster.xml: New file.
* tests/storagepoolxml2xmlout/pool-netfs-gluster.xml: Likewise.

efab27afbf Make logical pools independent on target path
When using logical pools, we had to trust the target->path provided.
This parameter, however, can be completely ommited and we can use
'/dev/<source.name>' safely and populate it to target.path.

eb0d79c64b storage_pool: Rework chap XML to mimic ceph
The existing 'chap' XML logic was never used - just defined.  Rather than
try to insert a square peg into a round hole, blow it up and rewrite the
logic to follow the 'ceph' format.

Remove the former "chap.login" and "chap.passwd" fields and replace
with "chap.username" and "chap.secret" in _virStoragePoolAuthChap.
Adjust the virStoragePoolDefParseAuthChap() to process.

Change the rng file to describe the new layout

Update the formatstorage.html to describe the usage of the secret element
to mention that the secret type "iscsi" and "ceph" can be used
to storage pool too.

Update the formatsecret.html to include a reference to the storage pool

Update tests to handle the changes from 'login' and 'passwd' to 'username'
and '<secret>' format

9f781da69d New XML attributes for storage pool source adapter
This introduces 4 new attributes for storage pool source adapter.
E.g.

<adapter type='fc_host' parent='scsi_host5' wwnn='20000000c9831b4b' wwpn='10000000c9831b4b'/>

Attribute 'type' can be either 'scsi_host' or 'fc_host', and defaults
to 'scsi_host' if attribute 'name' is specified. I.e. It's optional
for 'scsi_host' adapter, for back-compat reason. However, mandatory
for 'fc_host' adapter and any new future adapter types. Attribute
'parent' is to specify the parent for the fc_host adapter.

* docs/formatstorage.html.in:
  - Add documents for the 4 new attrs
* docs/schemas/storagepool.rng:
  - Add RNG schema
* src/conf/storage_conf.c:
  - Parse and format the new XMLs
* src/conf/storage_conf.h:
  - New struct virStoragePoolSourceAdapter, replace "char *adapter" with it;
  - New enum virStoragePoolSourceAdapterType
* src/libvirt_private.syms:
  - Export TypeToString and TypeFromString
* src/phyp/phyp_driver.c:
  - Replace "adapter" with "adapter.data.name", which is member of the union
    of the new struct virStoragePoolSourceAdapter now. Later patch will
    add the checking, as "adapter.data.name" is only valid for "scsi_host"
    adapter.
* src/storage/storage_backend_scsi.c:
  - Like above
* tests/storagepoolxml2xmlin/pool-scsi-type-scsi-host.xml:
* tests/storagepoolxml2xmlin/pool-scsi-type-fc-host.xml:
  - New test for 'fc_host' and "scsi_host" adapter
* tests/storagepoolxml2xmlout/pool-scsi.xml:
  - Change the expected output, as the 'type' defaults to 'scsi_host' if 'name"
    specified now
* tests/storagepoolxml2xmlout/pool-scsi-type-scsi-host.xml:
* tests/storagepoolxml2xmlout/pool-scsi-type-fc-host.xml:
  - New test
* tests/storagepoolxml2xmltest.c:
  - Include the test

37a10129c2 Update xml schemas according to libvirt source
capability.rng: Guest features can be in any order.
nodedev.rng: Added <driver> element, <capability> phys_function and
virt_functions for PCI devices.
storagepool.rng: Owner or group ID can be -1.

schema tests: New capabilities and nodedev files; changed owner and
group to -1 in pool-dir.xml.
storage_conf: Print uid_t and gid_t as signed to storage pool XML.

29bc4fe646 Add a sheepdog backend for the storage driver
This patch brings support to manage sheepdog pools and volumes to libvirt.
It uses the "collie" command-line utility that comes with sheepdog for that.

A sheepdog pool in libvirt maps to a sheepdog cluster.
It needs a host and port to connect to, which in most cases
is just going to be the default of localhost on port 7000.

A sheepdog volume in libvirt maps to a sheepdog vdi.
To create one specify the pool, a name and the capacity.
Volumes can also be resized later.

In the volume XML the vdi name has to be put into the <target><path>.
To use the volume as a disk source for virtual machines specify
the vdi name as "name" attribute of the <source>.
The host and port information from the pool are specified inside the host tag.

  <disk type='network'>
    ...
    <source protocol="sheepdog" name="vdi_name">
      <host name="localhost" port="7000"/>
    </source>
  </disk>

To work right this patch parses the output of collie,
so it relies on the raw output option. There recently was a bug which caused
size information to be reported wrong. This is fixed upstream already and
will be in the next release.

74951eadef storage backend: Add RBD (RADOS Block Device) support
This patch adds support for a new storage backend with RBD support.

RBD is the RADOS Block Device and is part of the Ceph distributed storage
system.

It comes in two flavours: Qemu-RBD and Kernel RBD, this storage backend only
supports Qemu-RBD, thus limiting the use of this storage driver to Qemu only.

To function this backend relies on librbd and librados being present on the
local system.

The backend also supports Cephx authentication for safe authentication with
the Ceph cluster.

For storing credentials it uses the built-in secret mechanism of libvirt.

265457845f xml: output memory unit for clarity
Make it obvious to 'dumpxml' readers what unit we are using,
since our default of KiB for memory (1024) differs from qemu's
default of MiB; and differs from our use of bytes for storage.

Tests were updated via:

$ find tests/*data tests/*out -name '*.xml' | \
  xargs sed -i 's/<\(memory\|currentMemory\|hard_limit\|soft_limit\|min_guarantee\|swap_hard_limit\)>/<\1 unit='"'KiB'>/"
$ find tests/*data tests/*out -name '*.xml' | \
  xargs sed -i 's/<\(capacity\|allocation\|available\)>/<\1 unit='"'bytes'>/"

followed by a few fixes for the stragglers.

Note that with this patch, the RNG for <memory> still forbids
validation of anything except unit='KiB', since the code silently
ignores the attribute; a later patch will expand <memory> to allow
scaled input in the code and update the RNG to match.

* docs/schemas/basictypes.rng (unit): Add 'bytes'.

20be699ee3 storage: add support for Vendor and Model in XML
I wrote a patch to add support for listing the Vendor and Model of a
storage pool in the storage pool XML.  This would allow vendor
extensions of specific devices.  The patch includes a test for the new
attributes as well.
