d1b59c6214 conf: Allow configuration of implicit controller model
When an implicit controller is added, the model is defined as -1
(IOW: undefined). So, if an implicit SCSI controller was added,
can set the model to the default value if the underlying hypervisor
supports it.

aa99cab737 test: Drop useless prefix for qemuargv2xml test data
There's no reason for the files to have qemuargv2xml- prefix

4fb8ff9987 conf: Drop virDomainChrDeviceType.targetTypeAttr
This attribute was used to decide whether to format the type
attribute of the <target> element, but the logic didn't take into
account all possible cases and as such could lead to unexpected
results. Moreover, it's one more thing to keep track of, and can
easily fall out of sync with other attributes.

Now that we have VIR_DOMAIN_CHR_SERIAL_TARGET_TYPE_NONE, we can
use that value to signal that no specific target type has been
configured for the serial device and as such the attribute should
not be formatted at all. All other values are now formatted.

8002d3cb1b conf: Add/Allow parsing the auth in the disk source
Since the virStorageAuthDefPtr auth; is a member of _virStorageSource
it really should be allowed to be a subelement of the disk <source>
for the RBD and iSCSI prototcols. That way we can set up to allow
the <auth> element to be formatted within the disk source.

Since we've allowed the <auth> to be a child of <disk>, we'll need
to keep track of how it was read so that when writing out we'll know
whether to format as child of <disk> or <source>. For the argv2xml
parsing, let's format under <source> as a preference. Do not allow
<auth> to be both a child of <disk> and <source>.

Modify the qemuxml2argvtest to add a parse failure when there is an
<auth> as a child of <disk> *and* an <auth> as a child of <source>.

Add tests to validate that if the <auth> was found in <source>, then
the resulting xml2xml and xml2arg works just fine.  The two new .args
file are exact copies of the non "-source" version of the file.

The virschematest will read the new test files and validate from a
RNG viewpoint things are fine

Update the virstoragefile, virstoragetest, and args2xml file to show
the "preference" to place <auth> as a child of <source>.

67a52f709a qemu: argv: parse qemu commandline memory arguments
Existing qemuParseCommandLineMem() will parse "-m 4G" format string.
This patch allows it to parse "-m size=8126464k,slots=32,maxmem=33554432k"
format along with existing format. And adds a testcase to validate the changes.

Parse the -M (or -machine) command line option before starting
processing in earnest and have a fallback ready in case it's not
present, so that while parsing other options we can rely on
def->os.machine being initialized.

f64f03b5b1 qemu: Provide default LUN=0 for iSCSI if not provided
https://bugzilla.redhat.com/show_bug.cgi?id=1477880

If the "/#" is missing from the provided iSCSI path, then we need
to provide the default LUN of /0; otherwise, QEMU will fail to parse
the URL causing a failure to either create the guest or hotplug
attach the storage.

During post parse, for any iSCSI disk or hostdev, scan the source
path looking for the presence of '/', if found, then we can assume
the LUN is provided.  If not found, alter the input XML to add the
"/0".  This will cause the generated XML to have the generated
value when the domain config is saved after post parse.

e6e26a899d tests: unify qemu binary paths for all qemu related tests
Our test data used a lot of different qemu binary paths and some

acc83afe33 vnc: add support for listen type 'socket'
VNC graphics already supports sockets but only via 'socket' attribute.
This patch coverts that attribute into listen type 'socket'.

For backward compatibility we need to handle listen type 'socket' and 'socket'
attribute properly to support old XMLs and new XMLs.  If both are provided they
have to match, if only one of them is provided we need to be able to parse that
configuration too.

To not break migration back to old libvirt if the socket is provided by user we
need to generate migratable XML without the listen element and use only 'socket'
attribute.

20a0fa8eb2 qemu: address: Remove QEMU_CAPS_DEVICE usage
All qemu versions we support have QEMU_CAPS_DEVICE, so checking
for it is redundant. Remove the usage.

The code diff isn't clear, but all that code is just inindented
with no other change.

Test cases that hit qemuDomainAssignAddresses but don't have
infrastructure for specifying qemuCaps values see lots of
churn, since now PCI addresses are in the XML output.

Upcoming patches are going to make the disk portion of these
test cases fail. In order to make it work, we would need to
extend the qemuargv2xml test infrastructure to handle qemuCaps.
This is worthwhile to do at some point but isn't critical.

Instead just drop the offending portion, which isn't even the
target of the test cases anyways

dd1400280e tests: Fix syntax in iSCSI auth/secret tests
While working on the tests for the secret initialization vector, I found
that the existing iSCSI tests were lacking in how they defined the IQN.
Many had IQN's of just 'iqn.1992-01.com.example' for one disk while using
'iqn.1992-01.com.example/1' for the second disk (same for hostdevs - guess
how they were copied/generated).

Typically (and documented this way), IQN's would include be of the form
'iqn.1992-01.com.example:storage/1' indicating an IQN using "storage" for
naming authority specific string and "/1" for the iSCSI LUN.

So modify the input XML's to use the more proper format - this of course
has a ripple effect on the output XML and the args.

Also note that the "%3A" is generated by the virURIFormat/xmlSaveUri
to represent the colon.

6d8b6d2847 conf: also mark the implicit video as primary
Commit 119cd06 started setting the primary bool for the first

However this was done before the addition of the implicit device.

Move this default to virDomainDefPostParseInternal,

e6ad2b69ae qemu: parse: drop redundant AddImplicitControllers
PostParse handles it for us now.

This causes some test suite churn; qemu's custom PostParse could is
now invoked before the generic AddImplicitControllers, so PCI
controllers end up sequentially in the XML before the generically
added IDE controllers. So it's just some XML reordering

73ed1d7401 tests: qemuargv2xml: hardcode disk auth usage
If a qemuargv has iscsi or ceph secrets on the command line, we will
convert that to XML like:

  <auth username='myname'>
    <secret type='iscsi'/>
  </auth>

This is not valid XML, as either a UUID or usage must be specified in
the secret block. It's not clear though how the argv2xml code can do
anything correct here, since XML like this requires a libvirt secret
object to have already been defined.

The current test suite handles this by blanking out any <secret> block
in the XML. This avoids domainschematest failures.

Instead of blanking, let's hardcode a usage= name. This lets us test
the other bits of generated <secret> XML, and is a step towards wiring
up VIR_TEST_REGENERATE_OUTPUT

e117bf642b tests: qemuargv2xml: separate from qemuxml2argv data
Most of the qemuargv2xml tests are parsing old style qemu command
lines (with -disk, -serial, etc), and it gets its input from
qemuxml2argv output.

But since we've raise the minimum supported qemu version to 0.12.0,
which supports -device, once that changes propagates through libvirt
the vast majority of qemuxml2argv output is _not_ going to be using
old style qemu options.

In preparation for this, switch qemuargv2xml to use its own copies
of input and output, so it's not tied to qemuxml2argv results.

This is just a straight copy of the current tests.
