Our docs/web generator would take the complete license text and put it
into the description of the file, since it depends on position of the
"Author:" line. Move the author line to the top and remove the spurious
emacs comment.

According to the autoconf manual, using '$(LN_S) -f' is not
portable; remove the target explicitly beforehand to work around
this limitation.

Adjust some slightly awkward indentation while at it.

And document that these specific bits are done at startup time for
back compat reasons

Now we can return early and save some indentation

    virsh # list --all
     Id    Name                           State
    ----------------------------------------------------
     1     test                           running

    virsh # connect frob
    error: Failed to connect to the hypervisor
    error: no connection driver available for frob

    virsh # list --all
    error: failed to connect to the hypervisor
    error: no valid connection
    error: no connection driver available for frob

Seems sensible IMO to just not clear out the old connection state
until the new virConnectOpen succeeds.

My commit 0d157957 crashes on a URI without a scheme, like via
'virsh --connect frob'

Add a check on uri->server too while we are at it, and centralize
them all

Commit a8743c39 removed keepalive_required attribute from daemon, added a test
case for it, but forgot to enable the test itself in virnetdaemontest.

Commit a4746114 renamed virnetservertest to virnetdaemontest to reflect some
refactor changes to virNetServer code (which moved daemon-related parts to
virNetDaemon module). Moving test data from virnetserverdata to
virnetdaemondata was also part of the commit, but the commit failed to clean
half of the files that were copied (rather than moved).

Re-do 0217089b so it does not add regression for commit c0726e07 that allowed to
print help without making a connection to the daemon.

The autoconf documentation recommends to always use this
construct when creating symbolic links with $(LN_S) to avoid
unexpected behavior.

The current rule fails if the target already exists:

  cd /home/jenkins/build/libvirt/lib && \
    ln -s libnss_libvirt.so.1 nss_libvirt.so.1
  ln: nss_libvirt.so.1: File exists
  Makefile:3357: recipe for target 'install-exec-hook' failed

However, all other rules concerned with installation are
idempotent and will happily overwrite an existing target,
so this one should as well.

We use $(LN_S) for creating symbolic links, but the appropriate
autoconf macro was not included among the checks for external
programs.

autotools provide those for our convenience, so let's use them
everywhere instead of mixing in native command invocation.

The only place that uses it doesn't warrant a separate label.

After failing to parse the perf event list, the code would return
failure without freeing the previously acquired object. Rearrange the
code to avoid the problem.

Currently, if a connection URI was specified on the command line by the
'-c' switch, virsh connects to it, but after connecting overrides its
value with the one it tries to obtain from the VIRSH_DEFAULT_CONNECT_URI
environment variable.

This makes virsh connecting to the wrong URI if it disconnects from the
hypervisor and then tries to reconnect, and also leaks the original connname.

Fix by calling virGetEnvBlockSUID() before virshParseArgv().

The proper nwfilter docs go into full detail, but we should still
have a brief bit about domain XML in the domain documentation

Our uninstall script is not exact counterpart of install one.
Therefore we are leaving couple of files behind. This should not

We have this code in our Makefile that tries to remove
/etc/libvirt/nwfilter if directory is left empty after all our
example nwfilters were uninstalled. However, the check for that
is missing quotation marks thus rendering the test useless:

test -z allow-arp.xml allow-dhcp-server.xml .. qemu-announce-self.xml || \
  rmdir "/some/path/libvirt.git/_install/etc/libvirt/nwfilter"
/bin/sh: line 0: test: too many arguments

On BSD we are creating this symlink to libnss_libvirt.so called
nss_libvirt.so. That's just the way it is on BSD. However, when
uninstalling, we try to remove libnss_libvirt.so instead of the
symlink. Moreover, if file we are trying to remove does not exist
we error out instead of ignoring the error.

We don't have input devices in SDK thus for define/dumpxml
operations to be consistent we need to:

1. on dumpxml: infer input devices from other parts of config.
It is already done in prlsdkLoadDomain.

2. on define: check that input devices are the same that
will be infer back on dumpxml operation.

The second part should be fixed.

Remove all the plumbing needed for the different qcow-create/kvm-img
non-raw file creation.

We can drop the error messages because CreateQemuImg will thrown an
error for us but with slightly less fidelity (unable to find qemu-img),
which I think is acceptable given the unlikeliness of that error in
practice.

This an ubuntu/debian packaging convention. At one point it may have
been an actually different binary, but at least as of ubuntu precise
(the oldest supported ubuntu distro, released april 2012) kvm-img is
just a symlink to qemu-img for back compat.

I think it's safe to drop support for it

qcow-create was a crippled qemu-img impl that shipped with xen. I
think supporting this was only relevant for really old distros
that didn't have a proper qemu package, like early RHEL5. I think
it's fair to drop support

virsh vol-clone is expected to clone a volume within a single
pool; it doesn't work for cloning across pools. Clarify the docs

https://bugzilla.redhat.com/show_bug.cgi?id=1103714

VIR_ERR_NO_SUPPORT maps to the error string

    this function is not supported by the connection driver

and is largely only used for when a driver doesn't have any
implementation for a public API. So its usage with invalid
net-update requests is a bit out of place. Instead use
VIR_ERR_OPERATION_UNSUPPORTED which maps to:

    Operation not supported

And is what qemu's hotplug routines use in similar scenarios

do_open and winsock_init don't follow the naming pattern of other
functions in this file. Rename them to match

This reverts commit 1e9808d3.

We shouldn't advertise libvirtd.socket activation, since currently
it means VM/network/... autostart won't work as expected.

We tried to find a middle ground by installing the config file without
an [Install] section, since systemd won't allow .socket to be enabled
without one... or at least it did do that; presently on f24 it allows
activating the socket quite happily. This also caused user confusion[1]

Just remove the socket file. I've filed a new RFE to track coming up
with a solution to the autostart problem[2], we can point users at that
if there's more confusion:

Commit 3a773c43 introduced the testCompareNetXML2XMLResult
enumeration; however, in one instance the result variable was
assigned a value from the very similar testCompareDocXML2XMLResult
enumeration, leading to a build error.

  networkxml2xmltest.c:33:42: error:
    implicit conversion from enumeration type 'testCompareDomXML2XMLResult'
    to different enumeration type 'testCompareNetXML2XMLResult'

  testCompareNetXML2XMLResult result = TEST_COMPARE_DOM_XML2XML_RESULT_SUCCESS;

Use the proper value (TEST_COMPARE_NET_XML2XML_RESULT_SUCCESS) instead.

Implement support for saving GIC capabilities in the cache and
read them back.

Take the GIC capabilities stored in a virQEMUCaps instance and
update a virDomainCaps instance appropriately.

Add information about GIC capabilities to virDomainCaps and update
the formatter to include them in the XML output.

We need to expose GIC capabilities in the domain capabilities
XML: update the schema to validate documents that contain the
new information.

QEMU introduced the query-gic-capabilities QMP command
with commit 4468d4e0f383: use the command, if available,
to probe available GIC capabilities.

The information obtained is stored in a virQEMUCaps
instance, and will be later used to fill in a
virDomainCaps instance.

The struct contains a single boolean field, 'supported':
the meaning of this field is too generic to be limited to
devices only, and in fact it's already being used for
other things like loaders and OSs.

Instead of trying to come up with a more generic name just
get rid of the struct altogether.
