6dd2a2ae63 virfile: Detect ceph as shared FS
https://bugzilla.redhat.com/show_bug.cgi?id=1665553

Ceph can be mounted just like any other filesystem and in fact is
a shared and cluster filesystem. The filesystem magic constant
was taken from kernel sources as it is not in magic.h yet.

5772885d28 lib: Use more of VIR_STEAL_PTR()
We have this very handy macro called VIR_STEAL_PTR() which steals
one pointer into the other and sets the other to NULL. The
following coccinelle patch was used to create this commit:

  @ rule1 @
  identifier a, b;
  @@

  - b = a;
    ...
  - a = NULL;
  + VIR_STEAL_PTR(b, a);

Some places were clean up afterwards to make syntax-check happy
(e.g. some curly braces were removed where the body become a one
liner).

0c8df11071 bhyve: implement support for commandline args
Implement support for passing custom command line arguments
to bhyve using the 'bhyve:commandline' element:

  <bhyve:commandline>
    <bhyve:arg value='-newarg'/>
  </bhyve:commandline>

 * Define virDomainXMLNamespace for the bhyve driver, which
   at this point supports only the 'commandline' element
   described above,
 * Update command generation code to inject these command line
   arguments between driver-generated arguments and the vmname
   positional argument.

virt-aa-helper: generate rules for gl enabled graphics devices
This adds the virt-aa-helper support for gl enabled graphics devices to
generate rules for the needed rendernode paths.

Example in domain xml:
<graphics type='spice'>
  <gl enable='yes' rendernode='/dev/dri/bar'/>
</graphics>

results in:
  "/dev/dri/bar" rw,

Special cases are:
- multiple devices with rendernodes -> all are added
- non explicit rendernodes -> follow recently added virHostGetDRMRenderNode
- rendernode without opengl (in egl-headless for example) -> still add
  the node

f80eae8c2a qemu: command: Don't format image properties for empty -drive
If a -drive has no image, using image properties makes qemu whine that
they should not be used.

This patch stops formating cache/readonly/... for empty drives
for the pre-blockdev syntax. Unfortunately those parameters can't be
added later when inserting media, but on the other hand qemu will start
with an empty drive.

Since we already were able to start a VM with such config previously due
to qemu ignoring them I've opted just to skip formatting them.
Additionally with -blockdev support it will work as expected as the
image properties will be formatted when adding the image itself which is
not possible without it.

511df17aec cpu_map: Add support for arch-capabilities feature
The feature was added to QEMU in 3.1.0 and it is currently blocking
migration, which is expected to change in the future. Luckily 3.1.0 is
new enough to give us migratability hints on each feature via
query-cpu-model-expension, which means we don't need to use the
"migratable" attribute on the CPU map XML.

The kernel calls this feature arch_capabilities and RHEL/CentOS 7.* use
arch-facilities. Apparently some CPU test files were gathered with the
RHEL version of QEMU. Let's update the test files to avoid possible
confusion about the correct naming.

Our use of INCLUDES in Makefile.am hearkens back to when we had to
cater to automake 1.9.6 (thanks, RHEL 5) which lacked AM_CPPFLAGS.
Modern Automake flags a warning that INCLUDES is deprecated, and
now that we mandate RHEL 7 or better (see commit c1bc9c66), we no
longer have to cater to the old spelling.  This change will also
make it easier to do per-binary CPPFLAGS.

07c9d6601d qemu: use line breaks in command line args written to log
The QEMU command line arguments are very long and currently all written
on a single line to /var/log/libvirt/qemu/$GUEST.log. This introduces

e6f53e7a4b storage: Fix build issue with MOUNT and VGCHANGE commands
Turns out there some build platforms that must not define MOUNT
or VGCHANGE in config.h... So moving the commands from the storage
backend specific module into a common storage_util module causes
issues for those platforms.

So instead of assuming they are there, let's just pass the command
string to the storage util API's from the storage backend specific
code (as would have been successful before).  Also modify the test
to determine whether the MOUNT and/or VGCHANGE doesn't exist and
just define it to (for example) what Fedora has for the path. Could
have just used "mount" and "vgchange" in the call, but that defeats
the purpose of adding the call to virTestClearCommandPath.

600462834f Remove all Author(s): lines from source file headers
In many files there are header comments that contain an Author:
statement, supposedly reflecting who originally wrote the code.
In a large collaborative project like libvirt, any non-trivial
file will have been modified by a large number of different
contributors. IOW, the Author: comments are quickly out of date,
omitting people who have made significant contribitions.

In some places Author: lines have been added despite the person
merely being responsible for creating the file by moving existing
code out of another file. IOW, the Author: lines give an incorrect
record of authorship.

With this all in mind, the comments are useless as a means to identify
who to talk to about code in a particular file. Contributors will always
be better off using 'git log' and 'git blame' if they need to  find the
author of a particular bit of code.

This commit thus deletes all Author: comments from the source and adds
a rule to prevent them reappearing.

The Copyright headers are similarly misleading and inaccurate, however,
we cannot delete these as they have legal meaning, despite being largely
inaccurate. In addition only the copyright holder is permitted to change
their respective copyright statement.

f2f84b4d4a tests: Introduce tests for storage pool xml to argv checks
Similar to qemuxml2argv and storagevolxml2argv, let's create some
tests to ensure that the XML generates a consistent command line.

Using the same list of pools as storagepoolxml2xmltest, start with
the file system tests (fs, netfs, netfs-cifs, netfs-gluster).

c658764dec qemu: Don't use -mem-prealloc among with .prealloc=yes
https://bugzilla.redhat.com/show_bug.cgi?id=1624223

There are two ways to request memory preallocation on cmd line:
-mem-prealloc and .prealloc attribute for a memory-backend-file.
However, as it turns out it's not safe to use both at the same
time. If -mem-prealloc is used then qemu will fully allocate the
memory (this is done by actually touching every page that has
been allocated). Then, if .prealloc=yes is specified,
mbind(flags = MPOL_MF_STRICT | MPOL_MF_MOVE) is called which:

a) has to (possibly) move the memory to a different NUMA node,
b) can have no effect when hugepages are in play (thus ignoring user
request to place memory on desired NUMA nodes).

Prefer -mem-prealloc as it is more backward compatible
compared to switching to "-numa node,memdev=  + -object
memory-backend-file".

dd45c2710f conf: domain: gfx: Iterate over graphics devices when doing validation
The QEMU validation code for graphics has been in place for a while, but
because it is only executed from virDomainDeviceInfoIterateInternal, it
was never run, since the iterator expects the device to have boot info
which graphics don't have. The unfortunate side effect of this whole mess
was that a few capabilities were missing from the test suite (as commit
d8266ebe1 demonstrated with graphics-spice-invalid-egl-headless test),
which in turn meant that a few graphics tests which expected a failure
happily accepted any failure the test runtime returned which made them
succeed. The impact of this was that we then allowed to start a domain
with multiple OpenGL-enabled graphics devices.

This patch enables iteration over graphics devices. Unsurprisingly,
a few tests started to fail as a result, so fix those too.

0d5244cc86 tests: Introduce negative versions of DO_TEST_CAPS_LATEST
It's fairly easy to forget to add a capability to the list of
capabilities for a negative test case which might yield (for us) very
unfortunate results. Therefore, introduce negative versions of
DO_TEST_CAPS_LATEST macros, so that real QEMU caps can be used with
tests that expect a failure too.

daf4e2abca tests: Adding test case to include multiple network definitions.
This commit includes a test case for multiple network definitions. It is
useful right now, but it will be more useful when the index used by LXC
version 3.X is implemented to support this new settings. The version 3.X
is using indexes to specify each network settings.

081bdb4d68 tests: fix dry run handling in network firewall test
The networkxml2firewalltest sets virCommand to dry run mode but doesn't
provide a callback to fill in stdout/stderr. As a result when the
firewall code queries rules it gets a NULL output and so never triggers
the callback to process output.

This trivial change just returns an empty string for the command output
in order to ensure the callback gets triggered. It has no effect right
now, but in future patches this will trigger greater test coverage.

0a1b565382 xenconfig: add support for openvswitch configuration
Add support for converting openvswitch interface configuration
to/from libvirt domXML and xl.cfg(5). The xl config syntax for
virtual interfaces is described in detail in the
xl-network-configuration(5) man page. The Xen Networking wiki
also contains information and examples for using openvswitch
in xl.cfg config format

https://wiki.xenproject.org/wiki/Xen_Networking#Open_vSwitch

Tests are added to check conversions of openvswitch tagged and
trunked VLAN configuration.
