[libvirt] [PATCH 00/14] Add ability to handle the <metadata> element using the API
by Peter Krempa
This series adds the initialy omitted functionality of changing the <metadata>
element using the virDomain[Get|Set]Metadata API.
First few patches are cleanup of some code noticed during implementation of the
other stuff.
Peter Krempa (14):
virsh-domain: Remove spurious ATTRIBUTE_UNUSED from cmdDesc
virsh-domain: Line up signal names array
qemu: Factor out body of qemuDomainGetMetadata for universal use
qemu: Factor out body of qemuDomainSetMetadata for universal use
conf: Factor out setting of metadata to simplify code
util: Add helper to convert libxml2 nodes to a string
virsh-domain: use virXMLNodeDump instead of xmlNodeDump
virsh-domain: Add command to allow modifications of XML metadata
conf: Add support for requesting of XML metadata via the API
conf: allow to add XML metadata using the virDomainSetMetadata api
lib: Don't force the key argument when deleting metadata
lxc: Add metadata modification APIs
test: Add <metadata> support into the test driver
tests: Add metadata tests

[libvirt] make check error

Hi guys,
I made a automated test for the libvirt code in git source repository right now, It reported a check error.
The operation steps and error info are as following:

[libvirt] [PATCH] build: fix VPATH build of remote driver
by Eric Blake
Commit 073e1575 tried to set things up so that 1) generated files
to be shipped in the tarball always live in srcdir, and 2) we have
no files in SOURCES that depend on any other files with a literal
$(srcdir) in the name, because that situation can cause confusing
results for the make expansion of $@ depending on whether the file
is found locally or via VPATH. But all my testing for that patch
was done incrementally, where all the protocol.[ch] files had
already been generated prior to the patch and were up-to-date in
the srcdir, and thus I missed one case where $@ causes grief in a
VPATH build from a fresh checkout:
We have a pattern rule for generating remote_protocol.[ch], and
what's more, the rule for protocol.c depends on protocol.h AND
on the protocol.x file. The pattern for protocol.c is only
satisfied via the VPATH lookup for protocol.x, and if protocol.h
doesn't yet exist, the VPATH rule kicks in and we end up with a
dependency on a file with $(srcdir) in the name. Based on make's
rules for $@, this resulted in make building remote_protocol.h
into srcdir (where we want it), then remote_protocol.c into
builddir (oops, not so good for the tarball), and also causes
the build to fail (the compiler can't find the .h if it lives
in a different directory than the .c):
CC remote/libvirt_driver_remote_la-remote_protocol.lo
remote/remote_protocol.c:7:29: fatal error: remote_protocol.h: No such file or directory
#include "remote_protocol.h"
^
compilation terminated.
As before, the fix is to hard-code the output file to go into
srcdir in spite of $@; but since this is in a pattern rule, we
are forced to use $@ in the recipe, so the patch is a bit
trickier than what was done in commit 073e1575.
* src/Makefile.am (%protocol.c, %protocol.h): Force output to srcdir.

[libvirt] [PATCH] conf: Don't corrupt metadata on OOM
by Peter Krempa
Eric Blake suggested that we could do a little better in case copying of
the metadata to be set fails. With this patch, the old metadata is
discarded after the new string is copied successfuly.

[libvirt] [PATCH] qemu: Fix memleak after commit 59898a88ce8431bd3ea249b8789edc2ef9985827
by Peter Krempa
If the ABI compatibility check with the "migratable" user XML is
successful, we would leak the originaly parsed XML from the user that
would not be used in this case.

[libvirt] [PATCH 0/2] Fix reverting of external snapshots with custom XML
by Peter Krempa
The external snapshot code mistakenly used non-"migratable" XMLs
in the save image which caused problems with restoring them
via the workaround way of doing virDomainRestore().
This series adds workaround to add compatibility with older snapshots
and fixes the problem in the snapshot code.
Unfortunately, this is not testable with unit tests. I'll try to
do a autotest virt-test test case for this particular issue.

[libvirt] [PATCH v2 0/6]qemu: add usb-bot scsi controller support
by Guannan Ren
BZ:https://bugzilla.redhat.com/show_bug.cgi?id=917702
v2: After discussion in BZ, qemu guys hope the usb-bot(+usb-uas) can be
supported although the absence of its hot-plug feature.
In this patch, libvirt gives an unsupported error in this case.
v1: https://www.redhat.com/archives/libvir-list/2013-September/msg00020.html
And as the missing of hot-plug feature, the replacement of usb-storage is
not a urgent thing. disk attached to usb-storage supports hot-plug/unplug
already.
Guannan Ren(6)
qemu: add usb-bot qemu cap flag
qemu: add usb-bot model scsi controller support
qemu: add usb-bot support from disks points of view
qemu: refactor out function to build scsi device qemu commandline
qemu: no hot-plug/unplug support currently for usb-bot
tests: add xml2argv test for usb-bot scsi controller

With a bit of delay, the release needed by Wido is finally available,
it is tagged in git and I have pushed tarball, jar and rpms to the FTP:
ftp://libvirt.org/libvirt/java/
Wido maybe you can push to Maven, I'm unsure how to do this and last
time I tried I made a mess :-)
I bumped the intermediate release number as this release includes
more improvements and fixes than the previous ones and deprecates a
couple of things:

- Implement virDomainMigrate2 and use it for a new migrate method. (Wido den Hollander)
- Overload Domain.snapshotCreateXML with a method that has an argument for flags (Wido den Hollander)
- Overload Domain.snapshotListNames with a method that has an additional flags argument. (Wido den Hollander)
- Implement virDomainUndefineFlags by overloading the existing undefine method (Wido den Hollander)
- Implement virStorageVolResize by adding resize to StorageVol (Wido den Hollander)
- Implement virDomainBlockResize (Wido den Hollander)
- Avoid creating new Arrays and Lists on every struct instantiation (Claudio Bley)
- Make the build fail if any of the JUnit tests have errors or failures (Claudio Bley)
- Avoid unnecessary copying and calling virResetLastError. (Claudio Bley)
- Split "build" target and automatically rebuild out of date files. (Claudio Bley)
- Split JUnit tests and use a fixture for Connect. (Claudio Bley)
- Call processError only if a libvirt function indicates an error. (Claudio Bley)
- Change visibility of class members to private to enforce encapsulation. (Claudio Bley)
- Make finalize() methods protected. (Claudio Bley)
- Add findbugs build file for ant. (Claudio Bley)
- Introduce a javac.debug property. (Claudio Bley)
- maint: correct name for license file (Eric Blake)
- Add Javadoc and Source JARs to Maven repo (Wido den Hollander)
- Fix the Maven build system with Ant (Wido den Hollander)
Cleanups:
- trivial remove unused imports (Stefan Majer)
- Remove unused imports (Stefan Majer)
