Currently, there's a bug when undefining a domain with NVRAM
store. Basically, the unlink() of the NVRAM store file happens
during the undefine procedure iff domain is inactive. So, if
domain is running and undefine is called the file is left behind.
It won't be removed in the domain cleanup process either
(qemuProcessStop). One of the solutions is to remove if
regardless of the domain state and rely on qemu having the file
opened. This still has a downside that if the domain is defined
back the NVRAM store file is going to be new, any changes to the
current one are lost (just like with any other file that is
deleted while a process has it opened). But is it really a
downside?

Rewrite virConfReadMem to take a null-terminated string.
All the callers were calling strlen on it anyway.

Make the comparison explicit.

If there's no content in <script></script>, the XSTL generator
will turn it into <script/> which is not permitted in XHTML.
Adding a single whitespace is enough to guarantee an explicit
closing tag. Without this, the scripts never get loaded by
the browser.

Slight refactor of the WMI serialization code to minimize mixing
openwsman and libxml2 APIs that triggered clang alignment warnings.

The only usage of libxml2 APIs now is in creating CDATA blocks,
because the openwsman API does not provide that functionality. The
clang alignment warning in this case is silenced by casting to a
void pointer first.

Validate that we can pass QEMU command line options using a default
namespace, instead of a prefixed namespace

The API docs for the various vir$OBJECTGetConnect functions
contain a warning

  WARNING: When writing libvirt bindings in other languages, do
  not use this function.  Instead, store the connection and
  the domain object together.

There is no reason why language bindings should not use this
method, and indeed the Perl, Python, and Go bindings all use
these methods.

This warning was originally added back in

  commit 3edb4bc9
  Author: Daniel Veillard <veillard@redhat.com>
  Date:   Tue Jul 24 15:32:55 2007 +0000

    * libvirt.spec.in NEWS docs/* po/*: preparing release 0.3.1
    * src/libvirt.c python/generator.py: some cleanup and warnings
      from Richard W.M. Jones

IIUC, the rational was that these APIs do not need to be
directly exposed to the non-C language, as the language
can expose the same concept itself by storing the original
virConnectPtr object alongside the virDomainPtr.  There's
no reason to mandate such an approach though - it is valid
for languages to expose this directly if that suits their
needs better.

However, the check for it might access a byte outside of the

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.

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.

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
deterministic seed.

Export the function from the util module so that dynamic linking can
override it.

The functions declared in virhash.h return bool, but stdbool.h was not
included.

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.

no DTD is present because HTML5 is no longer defined as an
