a253396a47 apibuild: Allow completely skipping certain macros
Some macros don't make sense to be documented at all. Add infrastructure
to the web/api generator and add VIR_DEPRECATED and VIR_EXPORT_VAR as
macros we should not document.

9b99bcf02c include: common: Fix file header for apibuild.py
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.

d0062fb9b5 dist: ln(1) is not guaranteed to have a '-f' option
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.

a02a859be4 virsh: Don't clear old connection if 'connect $uri' fails
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.

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

0217089b89 virsh: don't override connection URI from argv
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().

2df4685905 vz: fix config input device check
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.

272c622475 storage: drop the plumbing needed for kvm-img/qcow-create

We can drop the error messages because CreateQemuImg will thrown an

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.

it's fair to drop support

cdb4caac81 network: Don't use ERR_NO_SUPPORT for invalid net-update requests
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

3b9100a4d2 Revert "daemon: use socket activation with systemd"
This reverts commit 1e9808d3a1.

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:

0d1579572a Explicitly error on uri=qemu://system
It's a fairly common error that a user tries to connect to a URI
like qemu://system or qemu://session (missing a slash). This errors
like:

$ virsh --connect qemu://session
error: failed to connect to the hypervisor
error: Unable to resolve address 'session' service '16514': No address associated with hostname

If you already know that the standard qemu URI has 3 slashes, that
error will make it obvious enough. But new user's may not get it.
There's even a RHEL support page explicitly mentioning it!:

https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Virtualization_Deployment_and_Administration_Guide/sect-Troubleshooting-Common_libvirt_errors_and_troubleshooting.html

But upcoming update device functionality for cdroms
