43c0325b10 network: Make virtual domains resolvable from the host
This patch adds a new attribute "register" to the <domain> element. If
set to "yes", the DNS server created for the virtual network is
registered with systemd-resolved as a name server for the associated
domain. The names known to the dnsmasq process serving DNS and DHCP
requests for the virtual network will then be resolvable from the host
by appending the domain name to them.

e82f99283d virSocketSendMsgWithFDs: Don't report errors, just set errno
Currently, virSocketSendMsgWithFDs() reports two errors:

1) if CMSG_FIRSTHDR() fails,
2) if sendmsg() fails.

Well, the latter sets an errno, so caller can just use
virReportSystemError(). And the former - it is very unlikely to
fail because memory for whole control message was allocated just
a few lines above.

The motivation is to unify behavior of virSocketSendMsgWithFDs()
and virSocketSendFD() because the latter is just a subset of the
former (will be addressed later).

442061583e virt-admin: Add warning when connection to default daemon fails
The admin connection defaults to the system-wide 'libvirtd' daemon to
manage (libvirtd:///system). As we've now switched to modular daemons
this will not work for most users out of the box:

 $ virt-admin version
 error: Failed to connect to the admin server
 error: no valid connection
 error: Failed to connect socket to '/run/user/1000/libvirt/libvirt-admin-sock': No such file or directory

As we don't want to assume which daemon the user wants to manage in the
modular topology there's no reasonable default to pick.

Give a hint to the users to use the '-c' if the connection to the
default URI fails:

 $ virt-admin version
 NOTE: Connecting to default daemon. Specify daemon using '-c' (e.g. virtqemud:///system)
 error: Failed to connect to the admin server

The argument causes qemu to record 'raw' as the backing file format in
case when a protocol node is used directly. This is needed to preserve
compatibility of images after a block-commit or block-pull libvirt
operation with older libvirt versions in case when we'll want to remove
the unneded 'raw' format drivers from the block graph.

e355ea422d qemu-replies-tool: Add mode to dump all QMP schema query strings
Make the tool useful also for non-testing purposes by adding 'dump'
mode, which will process the data and output information about the qemu
version.

The first 'dump' mode produces all possible valid query strings per
virQEMUQAPISchemaPathGet/virQEMUCapsQMPSchemaQueries. This is useful for
users to look up a query string via 'grep' rather than trying to come up
with it manually.

Additionally the data as represented by qemu changes naming very often
and that makes it un-reviewable to find changes between two qemu builds.
By using the dump mode, which produces results in stable order we can
use it to 'diff' two .replies file without churn.

Sample output '[...]' denotes an arbitrary trim:

2866c1a457 scripts: Add 'qemu-replies-tool' script for testing and modifying data for qemucapabilitiestest
The tool in the current shape functionally replaces
tests/qemucapabilitiesnumbering.c

It validates that the output '.replies' files conform to how we generate
them from qemu and also allows programmatic modification of the
'.replies' files if re-generation is not feasible any more.

The main advantage is that JSON objects are parsed into native python
types and thus the programatic modification is much more convenient.

The tool will be later extended to also do validation that we properly
handle the whole of QMP schema as well as help in reviewing the
differences in the .replies file after qemu updates.

YAJL formats empty objects and arrays in a weird way:

We want to use empty lines to separate commands and replies as well as
be compatible with python's 'json.dump' method, thus we drop any
whitespace between array/object braces.

Adjust the two formatters which are used for capabilities and fix all
output files.

Note that the code is duplicated in qemucapabilitiesnumbering.c and
qemucapsprobemock.c, but later patches will replace
qemucapabilitiesnumbering.c by a python tool.

518e70158b qemu: Handle MODEL_SCSI_{AUTO,DEFAULT} appropriately
The qemuDomainGetSCSIControllerModel() function, which is
responsible for choosing a model for a SCSI controller that
didn't have one provided by the user, considers values >0 to
mean "model has been set".

Since MODEL_SCSI_AUTO == 0, this means that such a value is
considered the same as MODEL_SCSI_DEFAULT (-1). This makes
sense, as not specifying a model name or explicitly asking for
one to be automatically chosen intuitively should result in
the same behavior.

Specifically, there is no case in which a value of
MODEL_SCSI_AUTO or MODEL_SCSI_DEFAULT is encountered after the
initial controller creation: it is either replaced with an
actual model, or an error is raised.

Despite this, there are a few places in the QEMU driver where
we incorrectly treat these values as if they were actual
model names. To reduce confusion, make sure that no longer
happens.

0d095c6d47 tests: Add controller-scsi-auto
The "auto" SCSI controller model was introduced for use in the
ESX driver, but the QEMU driver doesn't reject the value.

Add a test case showing the behavior when such a configuration
is encountered.

The code abused 'VIR_INFO' as an attempt at error reporting. Rework the
code to return the usual 0/-1 and raise proper errors.

a352bcf1c6 virPCIVPDParseVPDLargeResourceFields: Refactor return logic
Rewrite the conditions after exiting the parser so that they are easier
to understand. This partially decreases the granularity of "error"
messages as they are not strictly necessary albeit for debugging.

As it was already observed in this code the logic itself often does
something else than the comment claims, thus the code logic is
preserved.

Changes:
 - any case when not all data was processed is aggregated together and
   gets a common "error" message
 - absence of 'checksum' field is checked separately
 - helper variables are removed as they are no longer needed
