[libvirt] [PATCH v4 0/7] Add new APIs to edit xml configuration of managed save state of a domain
by Kothapally Madhu Pavan
managedsave command offloads the user from managing the save state file.
It does not need the user to specify saved state file location, all it takes
is domain name to identify. This makes it much more comfortable to use in
emergency where immediate shutdowm is needed. But it doesn't provide a way
to edit XML description of the save state file without user going through an
extra effort to search manually where the file actually exists.
The series aims to overcome the above constraints by adding new APIs and
commands to seemlessly edit the managed save state XML description using
just the domain name. The Patches mainly make use of the save-image-edit
code flow only to simplify the above use case.
This patch set provides capability to Dump and Edit the XML configuration
associated with a saved state file of a domain which was created by the
managedsave command.
The new command carry the similar options as the save-image-<XXX> commands
to change the running state as to paused state or running on start.
This is equivalent to:
virsh managedsave-dumpxml domain-name > state-file.xml
vi state-file.xml (or make changes with your other text editor)
virsh managedsave-define domain-name state-file-xml
or you can simply use:
virsh managedsave-edit domain-name
It's always better when we get more.
Changes since v3:
- refracted version references from 3.6.0 to 3.7.0
- fixed typo in error message.
Changes since v2:
- refracted version references from 3.5.0 to 3.6.0
Changes since v1:
- qemu implementation called directly rather than going through
driver pointer in qemuDomainManagedSaveDefineXML.
- check whether the managed save state file exists and report a
error if it doesn't.

[libvirt] [PATCH] maint: correct quoting for gl_WARN_ADD
by Eric Blake
3 out of 4 uses of gl_WARN_ADD() were incorrectly adding "" around
the argument, which in turn resulted in the argument being used
unquoted (configure had gl_positive=""-fstack-protector-all"",
rather than the intended gl_positive="-fstack-protector-all").

[libvirt] [PATCH] daemon: logging: Fix --verbose option being ignored by the daemon
by Erik Skultety
Commit 94c465d0 refactored the logging setup phase but introduced an
issue, where the daemon ignores verbose mode when there are no outputs
defined and the default must be used. The problem is that the default
output was determined too early, thus ignoring the potential '--verbose'
option taking effect. This patch postpones the creation of the default
output to the very last moment when nothing else can change. Since the
default output is only created during the init phase, it's safe to leave
the pointer as NULL for a while, but it will be set eventually, thus not
affecting runtime.
Patch also adjusts both the other daemons.

[libvirt] [PATCH v2] qemu: Handle host devices not being available better
by Andrea Bolognani
We can't retrieve the isolation group of a device that's
not present in the system. However, it's very common for
VFs to be created late in the boot, so they might not be
present yet when libvirtd starts, which would cause the
guests using them to disappear.
Moreover, for other architectures and even ppc64 before
isolation groups were introduced, it's considered
perfectly fine to configure a guest to use a device
that's not yet (or no longer) available to the host,
with the obvious caveat that such a guest won't be able
to start before the device is available.
In order to be consistent, when a device's isolation
group can't be determined fall back to not isolating it
rather than erroring out or, worse, making the guest
disappear.

[libvirt] [libvirt-php PATCH v2 00/11] Refactor into smaller components
by Dawid Zamirski
As per [1], this patch series splits up the large libvirt-php.c into
components that (attempts) to resemble the structure of the libvirt
project. Each patch successive patch was compile-tested while the whole
series was verified with "make check" and a simple custom written PHP
script.
Changes from v1 [2]:
* rebase on master
* include PHP headers in util.h instead of libvirt-php.h this makes
header inter-dependencies easier to manage/understand
* also test each patch on PHP 5

Split up the bindings for libvirt snapshot API
