[libvirt] [python PATCH] maint: balance {} usage
by Eric Blake
Emacs gets lost when finding function boundaries when #ifdef
sections do not have balanced {}.
* libvirt-override.c (virPyDictToTypedParams): Avoid unbalanced {}
across ifdef.
Signed-off-by: Eric Blake <eblake(a)redhat.com>

This feels trivial, but it's also hacky enough that I'll wait
for a review.

[libvirt] [libvirt-python PATCH] setup: Make libvirt API XML path configurable
by Martin Kletzander
Adding a support for LIBVIRT_API_PATH evironment variable, which can
control where the script should look for the 'libvirt-api.xml' file.
This allows building libvirt-python against different libvirt than the
one installed in the system. This may be used for example in autotest
or by packagers without the need to install libvirt into the system.

[libvirt] [TCK][PATCH] Enable tests with a .pl extension
by Mike Latimer
The main libvirt-tck script only executes tests using the default (.t)
extension. This patch adds .t and .pl as valid extensions using the --ext
parameter. This is required to enable storage tests added in commit 97c6a506.

[libvirt] [PATCH] qemuDomainGetImageIds: Skip <seclabel/> without label
by Michal Privoznik
It's easy to shed the daemon these days. With this XML snippet:
<disk type='file' device='disk'>
<driver name='qemu' type='raw'/>
<source file='/some/dummy/path/test.bin'>
<seclabel model='dac' relabel='no'/>
</source>
<target dev='vdb' bus='virtio'/>
<readonly/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/>
</disk>
I get the SIGSEGV when starting the domain. The thing is, when
starting a domain, we check for its disk presence. For some reason,
when determining the disk chain, we parse the <seclabel/> (don't ask
me why). However, there's no label attribute in the XML, so we end up
calling virParseOwnershipIds() over NULL string:

[libvirt] Memory allocation/usage
by Vikas Kokare
We are trying to understand the memory allocation and usage for a KVM guest
using the libvirt java API version 0.5.0. A certain memoryStats(int) on the
Domain class allows you to fetch MemoryStatistic values.
Each of this statistic has a tag and a value. In our case, the values
returned were
[tag: 6 val:8388608
, tag:7 val:8466792
]
What are these tag values(6 and 7) representative of? Do they mean memory
allocated and memory used. If yes, how can we confirm that?
