This commit is similar to commit 0977ada8.The virsh manpage
lists options --uuid and --name as mutually exclusive if
option --details is specified when actually the option
--details is mutually exclusive and can't go with options
--uuid and/or --name. This patch rewords the virsh manpage
to state the correct meaning.

Needed storage_util.h - missed while merging '5f07c3c0' with
commit id '479a2f16'.
Signed-off-by: NOlga Krishtal <okrishtal@virtuozzo.com>

Commit id '5f07c3c0' 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.

Pool operations as well as all the Volume operations.

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
code combine with the Unmount code since all the Stop code did
was call the Unmount code.

Not only we should set the MTU on the host end of the device but
also let qemu know what MTU did we set.

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).

Currently xenconfig only supports the hpet timer for HVM domains.
Include support for tsc timer for both PV and HVM domains.

While at it, use members of libxl_tsc_mode enum instead of literal
int values.

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.

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.
Signed-off-by: NMichal Privoznik <mprivozn@redhat.com>

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.

Previous commit tried to change configure logic such that the
GLUSTER_CLI parameter would always be set:

  Date:   Mon Jan 9 15:56:12 2017 +0100

    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.

Previously when QEMU failed "drive_add" due to an error opening
a file it would report

  "could not open disk image"

These days though, QEMU reports

  "Could not open '/tmp/virtd-test_e3hnhh5/disk1.qcow2': Permission denied"

which we were not detecting as an error condition.

Separate the headers so that functions only required for testing of the
sheepdog backend are separated into their own file.

They are used only in the SCSI backend driver so there's no need to
pollute the headers.

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.

The storage driver helper functions that deal with parted were put into
the disk backend code but are used commonly across.

While local builds succeed fine, a build worker building in a
chroot environment is encountering the following error with
