The build was failing with:

  CCLD     lockd.la
libtool:   error: can't build i686-pc-cygwin shared library unless -no-undefined is specified

Rather than add yet another $(CYGWIN_EXTRA_LDFLAGS) to all the
impacted *_la_LDFLAGS, it was easier to just pull the extra
flags into ALL libraries via AM_LDFLAGS.

Then, fix lockd_la_LDFLAGS to include AM_LDFLAGS, like all other
libraries.

Imagine that you're creating a transient domain, but for some reason,
starting it fails. That is virLXCProcessStart() returns an error. With
current code, in the error handling code the domain object is removed
from the domain object list, @vm is set to NULL and controls jump to
enjob label where virLXCDomainObjEndJob() is called which dereference vm
leading to instant crash.

The fix is to end the job in the error handling code and only after that
remove the domain from the list and jump onto cleanup label instead of
endjob.

When adding the ability to build the pool during the start pool processing
using the similar flags as buildPool processing would use, the code was
essentially cut-n-pasted from storagePoolCreateXML.  However, that included
a call to virStoragePoolObjRemove which shouldn't happen within the
storagePoolCreate path since that'll remove the pool from the list of
pools only to be rediscovered if libvirtd restarts.

So on failure, just fail and return as we should expect

In qemu, enabling this feature boils down to adding the following
onto the command line:

  -global driver=cfi.pflash01,property=secure,value=on

However, there are some constraints resulting from the
implementation. For instance, System Management Mode (SMM) is
required to be enabled, the machine type must be q35-2.4 or
later, and the guest should be x86_64. While technically it is
possible to have 32 bit guests with secure boot, some non-trivial
CPU flags tuning is required (for instance lm and nx flags must
be prohibited). Given complexity of our CPU driver, this is not
trivial. Therefore I've chosen to forbid 32 bit guests for now.
If there's ever need, we can refine the check later.

This element will control secure boot implemented by some
firmwares. If the firmware used in <loader/> does support the
feature we must tell it to the underlying hypervisor. However, we
can't know whether loader does support it or not just by looking
at the file. Therefore we have to have an attribute to the
element where users can tell us whether the firmware is secure
boot enabled or not.

Since its release of 2.4.0 qemu is able to enable System
Management Module in the firmware, or disable it. We should
expose this capability in the XML. Unfortunately, there's no good
way to determine whether the binary we are talking to supports
it. I mean, if qemu's run with real machine type, the smm
attribute can be seen in 'qom-list /machine' output. But it's not
there when qemu's run with -M none. Therefore we're stuck with
version based check.

All these configurations are already covered for qemuxml2argv,
but there were no equivalent tests for qemuxml2xml.

Now that DO_TEST() can be passed capabilities, there is little
need to use DO_TEST_FULL() instead of DO_TEST().

This will allow us to remove most DO_TEST_FULL() usages. For the
time being, just add the extra argument to all DO_TEST() calls.

A bunch of cases were only being tested for WHEN_ACTIVE or
WHEN_INACTIVE. Use WHEN_BOTH for all except the very few that
actually require the existing setup.

Instead of testing it twice using WHEN_ACTIVE and WHEN_INACTIVE
separately, just use WHEN_BOTH.

The test case uses DO_TEST_PARSE_FLAGS_ERROR(), but doesn't
pass any parse flag. Use DO_TEST_PARSE_ERROR() instead.

DO_TEST_FAILURE() doesn't take a GIC version, but the GIC flag
was passed anyway. Get rid of all such occurrences.

While no leak was observed yet, there might be one if
virObjectEventClass is ever derived from another class. Because
in that case plain VIR_FREE() will not call dispose() from parent
classes possibly leaking some memory.

At the beginning of the test, some preparation work is done. For
instance new virSecurityManager is created. If this fails for
whatever reason, we try to fetch the latest error and print the
error message contained in it. However, if there's a bug in our
code and no error is reported, this approach will lead to crash,
while with virGetLastErrorMessage() it won't.

Call the vcpu thread info validation separately to decrease complexity
of returned values by qemuDomainRefreshVcpuInfo.

This function now returns 0 on success and -1 on error. Certain
failures of qemu to report data are still considered as success. Any
error reported now is fatal.

Validate the presence of the thread id according to state of the vCPU
rather than just checking the vCPU count. Additionally put the new
validation code into a separate function so that the information
retrieval can be split from the validation.

Use a name that contains the command used to get the information.

The function will eventually do more useful stuff than just detection of
thread ids.

If the VM is offline we can't retrieve the runtime statistical
information. Pinning could be retrieved but there are separate APIs for
that.

Assure that it's just one statement to avoid problems when used with
conditions.

Rather than formatting a string and splitting it back to a JSON object
add API that will take a JSON object directly.

Since 2bfa7513 virObjectEventNew can be passed a NULL 'uuid' value,
so drop the ATTRIBUTE_NONNULL annotation

Long, long ago before libxl_get_required_shadow_memory() was
made publicly available, its code was copied to the libxl driver
for calculating shadow memory requirements of HVM domains.

Long ago, libxl_get_required_shadow_memory() was exported in
libxl_utils.h and included in xen-devel packages everywhere.

Remove the copied code, which has become stale, and let libxl
provode a proper shadow memory value.
