With recent additions to the node device xml schema, an xml schema can
now describe a mdev device sufficiently for libvirt to create and start
the device using the mdevctl utility.
Note that some of the the configuration for a mediated device must be
passed to mdevctl as a JSON-formatted file. In order to avoid creating
and cleaning up temporary files, the JSON is instead fed to stdin and we
pass the filename /dev/stdin to mdevctl. While this may not be portable,
neither are mediated devices, so I don't believe it should cause any
problems.

This deletes all trace of gnulib from libvirt. We still
have the keycodemapdb submodule to deal with. The simple
solution taken was to update it when running autogen.sh.
Previously gnulib could auto-trigger refresh when running
'make' too. We could figure out a solution for this, but
with the pending meson rewrite it isn't worth worrying
about, given how infrequently keycodemapdb changes.

Converting from virObject to GObject is reasonably straightforward,
as illustrated by this patch for virIdentity
In the header file
- Remove
typedef struct _virIdentity virIdentity
- Add
#define VIR_TYPE_IDENTITY virIdentity_get_type ()
G_DECLARE_FINAL_TYPE (virIdentity, vir_identity, VIR, IDENTITY, GObject);
Which provides the typedef we just removed, and class
declaration boilerplate and various other constants/macros.
In the source file
- Change 'virObject parent' to 'GObject parent' in the struct
- Remove the virClass variable and its initializing call
- Add
G_DEFINE_TYPE(virIdentity, vir_identity, G_TYPE_OBJECT)
which declares the instance & class constructor functions
- Add an impl of the instance & class constructors
wiring up the finalize method to point to our dispose impl
In all files
- Replace VIR_AUTOUNREF(virIdentityPtr) with g_autoptr(virIdentity)
- Replace virObjectRef/Unref with g_object_ref/unref. Note
the latter functions do *NOT* accept a NULL object where as
libvirt's do. If you replace g_object_unref with g_clear_object
it is NULL safe, but also clears the pointer.

The colors are not based on the semantics of the message but rather
on the message itself. This means that the default human-perceived
semantics (red = bad, green = good) don't really apply and spotting a
color does not mean anythting.
This is amplified by the sheer amount of output which configure produces
and the fact that some of the messages have negative semantics or
additional output.
In case of any problem the user will have to go through everything
anyways as spotting a red or yellow line has 0 information value.
Here are a few examples:
1) some 'no' messages are not a problem:
checking minix/config.h presence... no
2) some 'no' messages are actually positive:
checking for special C compiler options needed for large files... no
3) in some cases a 'yes' would mean that something is broken or needs
workaround
checking whether stat file-mode macros are broken... no
checking whether wint_t is too small... no
checking whether stdint.h predates C++11... no
checking whether the inttypes.h PRIxNN macros are broken... no
checking whether clang gives bogus warnings for -Wdouble-promotion... no
checking whether gettimeofday clobbers localtime buffer... no
4) due to string match based colors extra text makes messages yellow
checking for a traditional french locale... none
checking for working nanosleep... no (mishandles large arguments)
checking for library containing gethostbyname... none required
checking whether mbrtowc handles incomplete characters... (cached) guessing yes
5) in some cases the yes/no is very context dependant
checking whether pthread_rwlock_rdlock prefers a writer to a reader... no
checking whether this build is done by a static analysis tool... no
6) detected paths to binaries and libs are yellow despite being present
checking for objdump... objdump
checking for atomic ops implementation... gcc
As of the reasons above I don't think the colorization of the configure
output helps users or developers to debug the build process and
thus is not worth the extra code or output clutter.

The colorization based on the string itself makes little to no sense as

configure: driver_modules: yes (CFLAGS='' LIBS='-ldl')
2) In some cases a 'no' is actually good:
configure: hal: no
3) Few good/recommended configuration options are still yellow:
configure: QEMU: qemu:qemu
while using 'root:root' would still be yellow.
4) fields dumping config (e.g. the warning flags line) is a giant blob
of colored text which makes little sense

The LIBVIRT_RESULT function takes two or three arguments. The
first one is the name of the result (aka CHECK_NAME). It is
printed before the colon character. The rest of the arguments is
printed after the character. To produce colourized output a
couple of changes needs to be made.
Firstly, we need to print the CHECK_NAME using "echo -n" so that
the new line is not appended at the end of the message. To
achieve this, AS_MESSAGE_N function is introduced. It's a
verbatim copy of AS_MESSAGE (which is just another alias to
AC_MSG_NOTICE) except it doesn't put '\n' at the EOL.
The alias is defined at /usr/share/autoconf-*/autoconf/general.m4
and the AS_MESSAGE is then defined at
/usr/share/autoconf-2.69/m4sugar/m4sh.m4.
Secondly, the rest of the arguments are printed colourized and to
achieve that and also keep printing them into the log file the

Historically URIs handled by the remote driver will always connect to
the libvirtd UNIX socket. There will now be one daemon per driver, and
each of these has its own UNIX sockets to connect to.
It will still be possible to run the traditional monolithic libvirtd
though, which will have the original UNIX socket path.
In addition there is a virproxyd daemon that doesn't run any drivers,
but provides proxying for clients accessing libvirt over IP sockets, or
tunnelling to the legacy libvirtd UNIX socket path.
Finally when running inside a daemon, the remote driver must not reject
connections unconditionally. For example, the QEMU driver needs to be
able to connect to the network driver. The remote driver must thus be
willing to handle connections even when inside the daemon, provided no
local driver is registered.
This refactoring enables the remote driver to be able to connect to the
per-driver daemons. The URI parameter "mode" accepts the values "auto",
"direct" and "legacy" to control which daemons are connected to.
The client side libvirt.conf config file also supports a "remote_mode"
setting which is used if the URI parameter is not set.
If neither the config file or URI parameter set a mode, then "auto"
is used, whereby the client looks to see which sockets actually exist
right now.
The remote driver will only ever spawn the per-driver daemons, or
the legacy libvirtd. It won't ever try to spawn virtproxyd, as
that is only there for IP based connectivity, or for access from
legacy remote clients.
If connecting to a remote host over any kind of ssh tunnel, for now we
must assume only the legacy socket exists. A future patch will introduce
a netcat replacement that is tailored for libvirt to make remote
tunnelling easier.
The configure arg '--with-remote-default-mode=legacy|direct' allows
packagers to set a default at build time. If not given, it will default
to legacy mode.
Eventually the default will switch to direct mode. Distros can choose
to do the switch earlier if desired. The main blocker is testing and
suitable SELinux/AppArmor policies.

Libvirtd can advertise itself over avahi. The feature is disabled by
default though and in practice I hear of no one actually using it
and frankly I don't think it's all that useful
The 'Open Connection' wizard has a disproportionate amount of code
devoted to this feature, but I don't think it's useful or worth
maintaining, so let's drop it
I've never heard of any other applications having support for using
mDNS to detect libvirtd instances. Though it is theoretically possible
something exists out there, it is clearly going to be a niche use case
in the virt ecosystem as a whole.
By removing avahi integration we can cut down the dependency chain for
