d8e8b63d30 libxl: Add a test suite for libxl_domain_config generator
The libxl library allows a libxl_domain_config object to be serialized
from/to a JSON string. Use this to allow testing of the XML to
libxl_domain_config conversion process. Test XML is converted to
libxl_domain_config, which is then serialized to json. A json template
corresponding to the test XML is converted to a libxl_domain_config
object using libxl_domain_config_from_json(), and then serialized
back to json using libxl_domain_config_to_json(). The two json
docs are then compared.

Using libxl to convert the json template to a libxl_domain_config
object and then back to json provides a simple way to account for
any changes or additions to the json representation across Xen
releases.

64665fa82f qemu: command: explicitly error for non-x86 default CPU
The code only currently handles writing an x86 default -cpu
argument, and doesn't know anything about other architectures.
Let's make this explicit rather than leaving ex. qemu ppc64 to
throw an error about -cpu qemu64

05583fcb37 qemu: command: rework adding of default cpu model
Certain XML features that aren't in the <cpu> block map to -cpu
flags on the qemu cli. If one of these is specified but the user
didn't explicitly pass an XML <cpu> model, we need to format a
default model on the command line.

The current code handles this by sprinkling this default cpu handling
among all the different flag string formatting. Instead, switch it
to do this just once.

This alters some test output slightly: the previous code would
write the default -cpu in some cases when no flags were actually
added, so the output was redundant.

b4f7793ce2 conf: fix formatting of smartcard devices
My commit 0c1d863 broke formatting of passthrough smartcard devices:
<smartcard mode='passthrough' type='spicevmc'/>

resulted in invalid XML:
    <smartcard mode='passthrough'>
       type='spicevmc'>
      <address type='ccid' controller='0' slot='0'/>
    </smartcard>

Split out chardev source formatting function into two -
one formatting the attributes and other formatting the subelements.

f536b0dd73 tests: deterministichash: Make hash tables arch-independent
It turns out that our implementation of the hashing function is
endian-dependent and thus if used on various architectures the testsuite
may have different results. Work this around by mocking virHashCodeGen
to something which does not use bit operations instead of just setting a

cc6d43bb49 qemu: command: align disk serial check to schema
Disk serial schema has extra '.+' allowed characters in comparison
with check in code. Looks like there is no reason for that as qemu
allows any character AFAIK for serial. This discrepancy is originated
in commit id '85d15b51' where the ability to add serial was added.

Alter the disk-serial test to add a disk with all the possible
characters listed as the serial value.

ace45e67ab virNetDaemonCallInhibit: Call virNetDaemonGotInhibitReply properly
So there are couple of issues here. Firstly, we never unref the
@pendingReply and thus it leaks.

==13279==    by 0x928DE3C: clone (in /lib64/libc-2.23.so)

Secondly, while we send the message, we are suspended ('cos we're
talking to a UNIX socket).  However, until we are resumed back
again the reply might have came therefore subsequent
dbus_pending_call_set_notify() has no effect and in fact the
virNetDaemonGotInhibitReply() callback is never called. Thirdly,
the dbus_connection_send_with_reply() has really stupid policy
for return values. To cite the man page:

  Returns
      FALSE if no memory, TRUE otherwise.

Yes, that's right. If anything goes wrong and it's not case of
OOM then TRUE is returned, i.e. you're trying to pass FDs and
it's not supported, or you're not connected, or anything else.
Therefore, checking for return value of
dbus_connection_send_with_reply() is not enoguh. We also have to
check if @pendingReply is not NULL before proceeding any further.

772a6e36a5 tests: qemumonitorjson: Old and empty test case for node name detection
Prior to qemu 2.5 the node names would not be generated, thus would be
missing from 'query-blockstats' and 'query-named-block-nodes'. Test that
the code correctly detects nothing.

Additionally make sure that a VM without disks does not cause problems.

The test case change is necessary as our test file checker does not play
well with empty files.
