Commit id '5f07c3c07' broke the freebsd build in the libvirt CI test
environment because the UMOUNT was not defined unless WITH_STORAGE_FS
is defined.
So remove the virStorageBackendUmountLocal from storage_util.c,h and
restore the code back in the storage_backend_fs.c and _vstorage.c
modules.
Added create/define/etc pool operations for vstorage backend.
Used the common/local pool API's from storage_util for operations
that are not specific to vstorage. In particular Refresh and Delete
Pool operations as well as all the Volume operations.

Added general definitions for vstorage pool backend including
the build options to add --with-storage-vstorage checking.
In order to use vstorage as a backend for a storage pool
vstorage tools (vstorage and vstorage-mount) need to be installed.

Move all the volume functions to storage_util to create local/common helpers
using the same naming syntax as the existing upload, download, and wipe
virStorageBackend*Local API's.
In the process of doing so, found more API's that can now become local
to storage_util. In order to distinguish between local/external - I
changed the names of the now local only ones from "virStorageBackend..."
to just "storageBackend..."

Just moving code around with minor adjustment to have the Stop

was call the Unmount code.
Not only we should set the MTU on the host end of the device but

So far we allow to set MTU for libvirt networks. However, not all
domain interfaces have to be plugged into a libvirt network and
even if they are, they might want to have a different MTU (e.g.
for testing purposes).

We use @ret to hold the actual return value of the function we

use different variables: @rv, @rc, etc. Honour this naming

The current logic around configuring timers in libxl based on
virDomainDef object is a bit brain dead. Unsupported timers are
silently ignored and tsc is only recognized if it is the first
timer specified.
Change the logic to reject unsupported timers and honor the tsc
timer regardless of its order when multiple timers are specified.
It is destructive to attempt reset on a pci- or cardbus-bridge, the
host can crash. The bridges won't contain any guest data and neither
they can be passed through using vfio/stub. So, no point in allowing a

We lacked of timestamp in tainting of guests log,
which bring troubles for finding guest issues:
such as whether a guest powerdown caused by qemu-monitor-command
or others issues inside guests.
If we had timestamp in tainting of guests log,
it would be helpful when checking guest's /var/log/messages.

Based on work of Mehdi Abaakouk <sileht@sileht.net>.
When parsing vhost-user interface XML and no ifname is found we
can try to fill it in in post parse callback. The way this works
is we try to make up interface name from given socket path and
then ask openvswitch whether it knows the interface.

The event needs to be emitted after the last monitor call, so that it's
not possible to find the device in the XML accidentally while the vm
object is unlocked.
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1414393
When generating a domain XML from native command (i.e. via
the connectDomainXMLFromNative call), we should use
interface type 'bridge' rather than 'ethernet' because we only
support bridges at this point.
As we don't have bridge name explicitly specified on the command line,
just use 'virbr0' as a default.
The recent deprecation in glibc (commit b76e065991ec) means the
module will fail to build entirely:
nss/libvirt_nss.c: In function '_nss_libvirt_gethostbyname_r':
nss/libvirt_nss.c:363:13: error: RES_USE_INET6 is deprecated [-Werror]
int af = ((_res.options & RES_USE_INET6) ? AF_INET6 : AF_INET);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This resolver option was removed shortly after being introduced,
and application using it are already broken anyway.

storage: gluster: Remove build-time dependency on the 'gluster' cli tool
This missed the fact that the AC_PATH_PROG call was itself inside an 'if'
conditional that would not be called in with_storage_gluster was false. As
a result, GLUSTER_CLI was still conditionally defined.
Just kill the GLUSTER_CLI parameter and AC_PATH_PROG call entirely and pass a
bare "gluster" string to virFindFileInPath instead.

The iSCSI backend driver was using stuff from the SCSI driver without
making sure that it's compiled in. Move the common code into the
storage_util.c since it does not contain any specific code.
The file backend code was mistakenly put into #if WITH_STORAGE_FS. This
is not necessary since all the backends just access files on disk, and
thus the code for WITH_STORAGE_DIR is sufficient to compile everything.
The file became a garbage dump for all kinds of utility functions over
time. Move them to a separate file so that the files can become a clean
interface for the storage backends.
While local builds succeed fine, a build worker building in a

If libvirt_parthelper is erroneously told to append the partition
separator 'p' onto the generated output for a disk pool using device
mapper that has 'user_friendly_names' set to true, then the error
recovery path will fail to find volume resulting in the pool being
in an unusable state.
So, augment the documentation to provide the better hint that the
part_separator='yes' should be set when user_friendly_names are not
being used. Additionally, once we're in the error path where the
returned name doesn't match the expected partition name try to see
if the reason is because the 'p' was erroneosly added. If so alter
the about to be removed vol->target.path so that the DiskDeleteVol
code can find the partition that was created and remove it.
If the voldef type is VIR_STORAGE_VOL_BLOCK, then as long as the
format is known, let's allow the probe to happen - gets a truer value
and the same probe/update would be allowed for the same volume defined
in a domain.
For volume processing in virStorageBackendUpdateVolTargetInfo to get
the capacity commit id 'a760ba3a7' added the ability to probe a volume
that didn't list a target format. Unfortunately, the code used the
virStorageSource (e.g. target->type - virStorageType) rather than
virStorageVolDef (e.g. vol->type - virStorageVolType) in order to
make the comparison. As it turns out target->type for a volume is
not filled in at all for a voldef as the code relies on vol->type.
Ironically the result is that only VIR_STORAGE_VOL_BLOCK's would get
their capacity updated.
This patch will adjust the code to check the "vol->type" field instead
as an argument. This way for a voldef, the correct comparison is made.
Additionally for a backingStore, the 'type' field is never filled in;
however, since we know that the provided path is a location at which
the backing store can be accessed on the local filesystem thus just
pass VIR_STORAGE_VOL_FILE in order to satisfy the adjusted voltype
check. Whether it's a FILE or a BLOCK only matters if we're trying to
get more data based on the target->format.

The tool is used for pool discovery. Since we call an external binary we
don't really need to compile out the code that uses it. We can check
whether it exists at runtime.
