[libvirt] [PATCH 0/6] Add virNodeGetCpuTime() API
by Minoru Usui
Hi, everyone.
I wrote new API called virNodeGetCpuTime().
It returns cumulative cpu time of the node from /proc/stat since node boots up.
Previous discussion is here.
http://www.mail-archive.com/libvir-list@redhat.com/msg32552.html
Minoru Usui (6):
[1/6] virNodeGetCpuTime: Expose new API
[2/6] virNodeGetCpuTime: Define internal driver API
[3/6] virNodeGetCpuTime: Implement public API
[4/6] virNodeGetCpuTime: Implement remote protocol
[5/6] virNodeGetCpuTime: Implement virsh support
[6/6] virNodeGetCpuTime: Implement linux support

[libvirt] [PATCH] qemu: Don't fail driver startup with ancient qemu
by Jiri Denemark
Failure to extract version info (e.g., because qemu binary is so ancient
that it doesn't even support -help) shouldn't be considered fatal since
we only need it to detect whether qemu supports bootindex option.

[libvirt] [PATCH] build: detect potentential uninitialized variables
by Eric Blake
Even with -Wuninitialized (which is part of autobuild.sh
--enable-compile-warnings=error), gcc does NOT catch this
use of an uninitialized variable:
{
if (cond)
goto error;
int a = 1;
error:
printf("%d", a);
}
which prints 0 (if the stack was previously wiped) if cond
was true. Clang will catch it, but we dont' use clang as
often. Using gcc -Wjump-misses-init gives false positives:
{
if (cond)
goto error;
int a = 1;
return a;
error:
return 0;
}
Here, a was never used in the scope of the error block, so
declaring it after goto is technically fine (and clang agrees);
however, given that our HACKING already documents a preference
to C89 decl-before-statement, the false positive warning is
enough of a prod to comply with HACKING.
[Personally, I'd _really_ rather use C99 decl-after-statement
to minimize scope, but until gcc can efficiently and reliably
catch scoping and uninitialized usage bugs, I'll settle with
the compromise of enforcing a coding standard that rejects
false positives.]
* acinclude.m4 (LIBVIRT_COMPILE_WARNINGS): Add -Wjump-misses-init.
* src/util/util.c (__virExec): Adjust offenders.
* src/conf/domain_conf.c (virDomainTimerDefParseXML): Likewise.

[libvirt] [PATCH v2] Improve SCSI volume key generation
by Daniel P. Berrange
An update of patch 10 from:
http://www.redhat.com/archives/libvir-list/2010-November/msg00555.html
The SCSI volumes get a better 'key' field based on the fully
qualified volume path. All SCSI volumes have a unique serial
available in hardware which can be obtained by sending a
suitable SCSI command. Call out to udev's 'scsi_id' command
to fetch this value
In v2:
- Only use scsi_id if HAVE_UDEV is defined. This ensures
use only on udev >= 145 and thus avoids problem of
different semantics on RHEL-5 vintage udev
- Use virCommandPtr instead of virExec
- Use VIR_FDOPEN instead of fdopen
* src/storage/storage_backend_scsi.c: Improve volume key
field value stability and uniqueness

[libvirt] [PATCH] Use gnulib's manywarnings & warnings modules
by Daniel P. Berrange
Remove custom code for checking compiler warnings, using
gl_WARN_ADD instead. Don't list all flags ourselves, use
gnulib's gl_MANYWARN_ALL_GCC to get all possible GCC flags,
then turn off the ones we don't want yet.
This patch alone doesn't buy us much. What we want is some
more followup patches, which remove entries from the
'dontwarn' list, fixing up the corresponding code problems.
We also need to fix our stack usage in many places so we can
lower the ridiculous size of -Wframe-larger-than=20480
* acinclude.m4: Rewrite to use gl_WARN_ADD and gl_MANYWARN_ALL_GCC
* bootstrap.conf: Add warnings & manywarnings
* configure.ac: Switch to gl_WARN_ADD
* m4/compiler-flags.m4: Obsoleted by gl_WARN_ADD

[libvirt] FYI, "Unable to create cgroup for ..."
by Jim Meyering
In case someone else encounters this...
Today none of my VMs would start on F15:
# virsh create rawhide.xml
error: Failed to create domain from rawhide.xml
error: Unable to create cgroup for rawhide: No such file or directory
Luckily, I noticed that Rich Jones had the same problem
a week ago and he found that restarting libvirtd was enough
to solve the problem:
# service libvirtd restart
That did it for me, too.

[libvirt] Entering 0.9.0 freeze week, RC1 version to test
by Daniel Veillard
Okay, I pushed new localization updates around and generated a
first release candidate build for 0.9.0 at:
ftp://libvirt.org/libvirt/libvirt-0.9.0-rc1.tar.gz
I will regenerate a rc2 as soon as Eric pending patch queue and
outgoing fd patches are in as I think they should really make 0.9.0
There may be more infrastrcucture patches from Dan too, I'm unsure
and as usual pushing bug fixes are okay too,
thanks for giving it a try, it seems to work fine here at least
for basic tasks,
Daniel
