Commit b3f2b4ca5c left buf unallocated in
the case of QMP capability probing being used, leading to a segfault in
strlen in the cleanup path.
This patch opens the log and allocates the buffer if QMP probing was
used, so we can display the helpful error message.
Despite our great effort we still parsed qemu log output.
We wouldn't notice unless upcoming qemu 1.4 changed the
format of the logs slightly. Anyway, now we should gather
all interesting knobs like pty paths from monitor. Moreover,
since for historical reasons the first console can be just
an alias to the first serial port, we need to check this and
copy the pty path if that's the case to the first console.
A recent build failure made me realize that we could usefully add
a bit more information to configure output, for aid in analysis of
failed builds. Pulling in the autobuild module merely adds these
four lines to configure output:
configure: autobuild project... libvirt
configure: autobuild revision... v1.0.1-113-g7a74eea
configure: autobuild hostname... myhost
configure: autobuild timestamp... 20130102T233543Z
which can be useful even if not using the Autobuild project to parse
build logs.
* bootstrap.conf (gnulib_modules): Add autobuild.
* configure.ac: Favor git version over release version, when available.
'make syntax-check' warned that gnulib's copyright is now out of date.
* .gnulib: Update to latest, for copyright year bump.
* gnulib/local/m4/ssize_t.m4.diff: Regenerate.
* bootstrap: Synchronize from upstream.
This reverts commit 28224c4d2a
which shouldn't be needed at all because with current qemu
we obtain all paths from 'query-chardev' output. We ought
not parse log output at all anymore.
Since 586502189edf9fd0f89a83de96717a2ea826fdb0 qemu commit, the log
lines reporting chardev's path has changed from:
$ ./x86_64-softmmu/qemu-system-x86_64 -serial pty -serial pty -monitor pty
char device redirected to /dev/pts/5
char device redirected to /dev/pts/6
char device redirected to /dev/pts/7
to:
$ ./x86_64-softmmu/qemu-system-x86_64 -serial pty -serial pty -monitor pty
char device compat_monitor0 redirected to /dev/pts/5
char device serial0 redirected to /dev/pts/6
char device serial1 redirected to /dev/pts/7
However, with current code we are not prepared for such change, which
results in us being unable to start any domain.
Since sanlock doesn't run under root:root, we have chown()'ed the
__LIBVIRT__DISKS__ lease file to the user:group defined in the
sanlock config. However, when writing the patch I've forgot about
lease files for each disk (this is the
/var/lib/libvirt/sanlock/<md5>) file.
With our recent renames under src/util/* we forgot to adapt
python wrapper code generator. This results in some methods being
not exposed:
$ python examples/domain-events/events-python/event-test.py

AttributeError: 'module' object has no attribute 'virEventRegisterImpl'
Many internal qemu APIs must find domain object from passed
virDomainPtr. And with function Peter's introduced, we can use it
instead of copying multiple lines among code.
Since we switched to QMP probing, the object types are spelled out
explicitly, i.e. virtio-net-pci. This has effectively disabled
the capability detection of s390 virtio devices. The trivial fix
is to add the s390 virtio types explicitly to qemuCapsObjectProps.

This is an adjustment to the fix for
https://bugzilla.redhat.com/show_bug.cgi?id=889319
to account for two bonehead mistakes I made.
commit ac2797cf2a attempted to fix a
problem with netlink in newer kernels requiring an extra attribute
with a filter flag set in order to receive an IFLA_VFINFO_LIST from
netlink. Unfortunately, the #ifdef that protected against compiling it
in on systems without the new flag went a bit too far, assuring that
the new code would *never* be compiled, and even if it had, the code
was incorrect.
The first problem was that, while some IFLA_* enum values are also
their existence at compile time, IFLA_EXT_MASK *isn't* #defined, so
checking to see if it's #defined is not a valid method of determining
whether or not to add the attribute. Fortunately, the flag that is
being set (RTEXT_FILTER_VF) *is* #defined, and it is never present if
IFLA_EXT_MASK isn't, so it's sufficient to just check for that flag.
And to top it off, due to the code not actually compiling when I
thought it did, I didn't realize that I'd been given the wrong arglist
to nla_put() - you can't just send a const value to nla_put, you have
to send it a pointer to memory containing what you want to add to the
message, along with the length of that memory.
This time I've actually sent the patch over to the other machine
that's experiencing the problem, applied it to the branch being used
(0.10.2) and verified that it works properly, i.e. it does fix the
problem it's supposed to fix. :-/

The code for doing a block-copy was supposed to track the destination
file in drive->mirror, but was set up to do all mallocs prior to
starting the copy so that OOM wouldn't leave things partially started.
However, the wrong variable was being written; later in the code we
silently did 'disk->mirror = mirror' which was still NULL, and thus
leaking memory and leaving libvirt to think that the mirror job was
never started, which prevented a pivot operation after a copy.
Problem introduced in commit 35c7701c6.
* src/qemu/qemu_driver.c (qemuDomainBlockCopy): Initialize correct
variable.
To bring in line with new naming practice, rename the=
src/util/cgroup.{h,c} files to vircgroup.{h,c}

Currently, it only considers PTY backend serial devices for pseries.
It need to support all kinds of serial devices.
This patch is to fix the problem which is that it doesn't work
when specifying source type as file.

ACPI is only supported on x86 platform, PPC can't support it.
