The virStoragePoolObjSourceFindDuplicate logic used by PoolCreateXML
and PoolDefineXML avoids comparing the new definition against "other"
pool types. This can cause unexpected corruption if two different pool
source types used the same source device path. For example, a 'disk'
pool using source type device=/dev/sdc could be unwittingly overwritten
by using /dev/sdc for a 'logical' pool which also uses the source
device path.
So rather than blindly ignoring those checks when def->type !=
pool->def->type - have the pool->def->type switch logic handle the
check for which def->type's should be checked.
Refactor virStoragePoolObjSourceFindDuplicate into smaller units
separated by the "supported" pool source type. The ISCSI, FS,
LOGICAL, DISK, and ZFS pools can use "<source>... <device='%s'/>...
</source>".
Alter the logic slightly to return the matching pool or NULL rather
than setting matchpool = pool and break. Easier to read that way.
In the effort to reduce the virStoragePoolObjSourceFindDuplicate logic,
create a new helper which will handle all the ISCSI type differences.
Alter things just a little bit to return NULL or pool rather than
using breaks and matchpool = pool, then break. Also rather than creating
variables withing the if...else if... conditions, have them all at the
top of the function to make things a bit easier to read.

Currently, if we want to zero out disk source (e,g, due to
startupPolicy when starting up a domain) we use
virDomainDiskSetSource(disk, NULL). This works well for file
based storage (storage type file, dir, or block). But it doesn't
work at all for other types like volume and network.
So imagine that you have a domain that has a CDROM configured
which source is a volume from an inactive pool. Because it is
startupPolicy='optional', the CDROM is empty when the domain
starts. However, the source element is not cleared out in the
status XML and thus when the daemon restarts and tries to
reconnect to the domain it refreshes the disks (which fails - the
storage pool is still not running) and thus the domain is killed.

Clean up the virsh man page description for --pool-create-as in order
to better describe how the various arguments are used when creating
(or defining) a logical pool.
Also modify the storage pool XML parsing algorithm to check for the
mismatched "name" and "source-name".
While parsing if the storage source is not present, then a defaultFormat
was not set. This could lead to oddities such as seeing "unknown" format
in output for the "logical" pool even though the only format the pool could
support would be "lvm2".
This does "put a label" on other pool defaults as follows:
File System: FS_AUTO
Network File System: NETFS_AUTO
Disk: UNKNOWN
Each of which is the "0" value for their respective pools and thus
would be no "real" change.
The frequency is documented and formatted as an attribute of the <timer>
element rather than a nested <frequency> element expected by the parser.
Luckily enough, timer frequency has not been used by any driver so far.

QEMU 2.9 introduces the pcie-root-port device, which is
a generic version of the existing ioh3420 device.
Make the new device available to libvirt users.
Commit id 'bb74a7ffe' added a fairly non specific message when providing
only the <parent wwnn='xxx'/> or <parent wwpn='xxx'/> instead of providing
both wwnn and wwpn. This patch just modifies the message to be more specific
about which was missing.
Rather than returning true/false and having the caller check if the
vHBA was actually created, let's do that check within the CreateVport
function. That way the caller can faithfully assume success based
on a name start the thread looking for the LUNs. Prior to this change
it's possible that the vHBA wasn't really created (e.g if the call to
virVHBAGetHostByWWN returned NULL), we'd claim success, but in reality
there'd be no vHBA for the pool. This also fixes a second yet seen
issue that if the nodedev was present, but the parent by name wasn't
provided (perhaps parent by wwnn/wwpn or by fabric_name), then a failure
would be returned. For this path it shouldn't be an error - we should
just be happy that something else is managing the device and we don't
have to create/delete it.
The end result is that the createVport code can now just start the
refresh thread once it gets a non NULL name back.

This setting - just like its name suggest already - enables
sharing the nvdimm module with other applications. Under the hood
it controls whether qemu mmaps() the file as MAP_PRIVATE or
MAP_SHARED.

NVDIMM is new type of memory introduced into QEMU 2.6. The idea
is that we have a Non-Volatile memory module that keeps the data
persistent across domain reboots.
At the domain XML level, we already have some representation of
'dimm' modules. Long story short, NVDIMM will utilize the
existing <memory/> element that lives under <devices/> by adding
a new attribute 'nvdimm' to the existing @model and introduce a
new <path/> element for <source/> while reusing other fields. The
resulting XML would appear as:
<memory model='nvdimm'>
<source>
<path>/tmp/nvdimm</path>
</source>
<target>
<size unit='KiB'>523264</size>
<node>0</node>
</target>
<address type='dimm' slot='0'/>

When libvirtd is started we call qemuDomainRecheckInternalPaths
to detect whether a domain has VNC socket path generated by libvirt
based on option from qemu.conf. However if we are parsing status XML
for running domain the existing socket path can be generated also if
the config XML uses the new <listen type='socket'/> element without
specifying any socket.
The current code doesn't make difference how the socket was generated
and always marks it as "fromConfig". We need to store the
"autoGenerated" value in the status XML in order to preserve that
information.
The difference between "fromConfig" and "autoGenerated" is important
for migration, because if the socket is based on "fromConfig" we don't
print it into the migratable XML and we assume that user has properly
configured qemu.conf on both hosts. However if the socket is based
on "autoGenerated" it means that a new feature was used and therefore
we need to leave the socket in migratable XML to make sure that if
this feature is not supported on destination the migration will fail.

Rather than the inlined VIR_FREE's, use a cleanup: label... Fixes an
issue introduced by 03346def where @name was free'd before usage in
a virAsprintf to format scsi_host_name.
The niothreadids struct field is size_t, so must use %zu not %lu
with printf. While they're identical on some platforms, on others
they are different, causing warnings

Add a test that allows providing the parent fabric_wwn in the input XML
in order to create the vHBA.
This also fixes a mixed setting of the fabric_wwn field from the read
test driver XML strings.
Rework the code to perform the various searches by parent, parent_wwnn/
parent_wwpn, parent_fabric_wwn, or vport capable in order to return the
'parent_host' number that is vHBA capable.
The former virNodeDeviceGetParentHost is renamed to add the ByParent
on it fixes an issue where if no parent was supplied in the XML to
create the vHBA, then virNodeDeviceFindByName was called with a NULL
second parameter which had bad results.
The reworked code will make the various calls to fetch the NPIV host
by the passed parameter options or if none are provided find a vport
capable NPIV HBA to perform the create. If the call is from the delete
path, then this option won't be allowed.
Each of virNodeDeviceGetParentHostBy* functions is now static, so
remove them external definitions.
A secondary benefit of this is the test_driver now can make use of
the new API to add some new tests to test the various creation options.
Create a virscsihost.c and place the functions there. That removes the
last #ifdef __linux__ from virutil.c.
Take the opporunity to also change the function names and in one case
the parameters slightly
Use the new virNodeDeviceGetParentName instead. Modify the callers to
build the node device scsi_host# name string in order to call the new
function so that proper lookup occurs.
Rather than have them mixed in with the virutil apis, create a separate
virvhba.c module and move the vHBA related calls into there. Soon there
will be more added.
Also modify the names of the functions and some arguments to be more
indicative of what is really happening. Adjust the callers respectively.
While I was changing fchosttest, rather than the non-descriptive names
test1...test6, rename them to match what the test is doing.

Fix by using intermediate variable to store the result similarly
to how it's done for other FromString* calls.
After 7f1bdec5fa our nodedev driver is capable of
determining DRM devices (DRM stands for Direct Render Manager not
Digital rights management). There is still one bit missing
though: virConnectListAllNodeDevices() is capable of listing
either all devices or just those with specified capability. Well,
DRM capability is missing there.

When the 'parent' was added to the virNodeDevicePtr structure
by commit id 'e8a4ea75a' the 'parent' field was not properly filled
in when a virGetNodeDevice call was made within driver/config code.
Only the device name was ever filled in. Fetching the parent required
a second trip via virNodeDeviceGetParent into the node device lookup
code was required in order to retrieve the specific parent field (and
still the parent field was never filled in although it was free'd).
Since we have the data when we initially call virGetNodeDevice from
within driver/node_config code - let's just fill in the parent field
as well for anyone that wants it without requiring another trip into
the node_device lookup just to get the parent.
This will allow API's such as virConnectListAllNodeDevices,
virNodeDeviceLookupByName, and virNodeDeviceLookupSCSIHostByWWN
to retrieve both name and parent in the returned virNodeDevicePtr.
