[libvirt] [PATCH] virsh: Add a white line into secret-get-value output
by liyang
From: Li Yang <liyang.fnst(a)cn.fujitsu.com>
Commonly there is a whilt line at the end of the virsh
command output, for example:
[root@localhost /]# virsh list --name --all
virt-tests-vm1
[root@localhost /]#
For now the output of secret-get-value like this:
[root@localhost /]# virsh secret-get-value b7811f0f-7fcb-d6b0-c12c-2d8807814b33
00111111001111110011111100111111
[root@localhost /]
So modify the codes, make output like this:
[root@localhost /]# virsh secret-get-value b7811f0f-7fcb-d6b0-c12c-2d8807814b33
00111111001111110011111100111111
[root@localhost /]

[libvirt] [PATCH] storage: add check for invalid volume name
by Jincheng Miao
If volume name is a path, storageVolCreateXML appends that name to
the specified pool path, that will taint other pools. Adding the
volume check is better for sanity.

[libvirt] [PATCH v4] Introduce --without-pm-utils to get rid of pm-is-supported dependency
by Cédric Bosdonnat
This uses the dbus api of systemd to check the power management
capabilities of the node.
---
Diff with v3:
* Added unit tests vir virSystemdCan* helpers
* Make the default for with-pm-utils depending on dbus and systemd detection
* Changed the implementation of the helpers to return true for
'yes' and 'challenge' responses, we shouldn't get a 'no' given libvirtd runs
as privileged user... but who knows.

[libvirt] [PATCH v2 1/1] Enable QEMU_CAPS_PCI_MULTIBUS capability for QEMU2.0 forward on PPC64.
by Li Zhang
From: Li Zhang <zhlcindy(a)linux.vnet.ibm.com>
For QEMU2.0 forward version on PPC64, it supports PCI multibus.
Currently, libvirt still disables it which causes an error
"Bus 'pci' not found".

[libvirt] [PATCH 0/5] progress towards removing virStorageFileMetadata
by Eric Blake
I'm almost to the point where virStorageSource can track everything
that virStorageFileMetadata was used for, so that we can use one
struct instead of two. But while working on this today, I noticed
that virStorageFileChainLookup() does not have any unit tests, so
I'll be writing those before removing the two remaining redundant
fields.
Eric Blake (5):
conf: provide details on network backing store
conf: expose probe for non-local storage
conf: delete useless backingStoreIsFile field
conf: return backing information separately from metadata
conf: delete useless backingStoreFormat field

[libvirt] [PATCH] conf: make virstoragetest debug easier
by Eric Blake
I'm tired of alternating between test failures due to bugs in
my refactoring work, vs. test failures due to leftovers in
the file system from the previous test. This patch has no
impact when the testsuite is successful, but doeesn't hurt either.

failed test.

[libvirt] [PATCH 00/13] Add multiple trace backend function and add new ftrace backend for libvirt
by yangzy.fnst＠cn.fujitsu.com
From: Xinghai Yu <yuxinghai(a)cn.fujitsu.com>
This patch set will let libvirt to support multiple trace backend function
and add a new 'ftrace' backend at the same time.
Then, libvirt would have 2 trace backend: dtrace, ftrace.They can be used
alone or together.
Patchs 1,2,3,4,5 are used for supporting multiple trace backend function.
Patch 6 are used for adding ftrace as a new trace backend for libvirt.
Patchs 7,8,9,10,11,12,13 add ftrace initial code in programs who use it.
Thanks very much for Stefan Hajnoczi for I have used his scripts in patch
4 which commited in qemu.
Thanks very much for Eiichi Tsukata for I have used his ftrace codes in
patch 6 which commited in qemu.
Backgroud:
The existing trace mechanism in libvirt is dtrace. Although the dtrace
can work, it's not work well enough. Every time we want get information
from the trace point we must write a systemtap script and run it
together with libvirt.
That's really unpractical on some occasion, especially on production
server since the systemtap script can't be executed automatically.
And some problems may be not easy to reproduce, then it will cost a
lot of time to get the trace information again.
So I think it is essential to add supporting for record the trace
information automatically in libvirt to satisfy the user's requirement.
That's why I implemented multiple trace backend function and ftrace
support in libvirt.
Xinghai Yu (13):
configure.ac: Define new macro 'WITH_TRACE_PROBES' to indicate trace
function are available
Makefile.am: Add new multiple trace backend supporting framework
src: Use new tracepoint declaration files to replace the old dtrace
declaration files to support multiple trace function
src: Add scripts 'tracetool' to supporting the translation from
tracepoint files to multiple trace backend supporting files
daemon,src: Use new tracepoint function calls to replace old PROBE
macro calls to support multiple trace function
configure.ac, Makefile.am, src: Add new ftrace backend
src/libvirt.c: Init ftrace backend in libvirt library so that programs
containing it can use ftrace
src/qemu/qemu_driver.c: Init ftrace backend in qemu driver so that
qemu driver can support ftrace
src/locking/lock_daemon.c: Init ftrace backend in program 'virtlockd'
src/util/iohelper.c: Init ftrace backend in program 'libvirt_iohelper'
src/storage/parthelper.c: Init ftrace backend in program
'libvirt_parthelper'
src/lxc/lxc_controller.c: Init ftrace backend in program 'libvirt_lxc'

[libvirt] [PATCH] Add support for timestamping QEMU logs
by Ján Tomko
QEMU commit 5e2ac51 added a boolean '-msg timestamp=[on|off]'
option, which can enable timestamps on errors:
$ qemu-system-x86_64 -msg timestamp=on zghhdorf
2014-04-09T13:25:46.779484Z qemu-system-x86_64: -msg timestamp=on: could
not open disk image zghhdorf: Could not open 'zghhdorf': No such file or
directory
Enable this timestamp if the QEMU binary supports it.
Add a 'log_timestamp' option to qemu.conf for disabling this behavior.

[libvirt] [PATCH 0/6] qemuDomainGetPercpuStats cleanups
by Ján Tomko
This series removes qemuDomainGetPercpuStats in favor of
virCgroupGetPercpuStats, fixes incorrect startcpu
boundaries check and cleans the code up.
Ján Tomko (6):
Don't require domain obj in qemuDomainGetPercpuStats
Fix return value of virCgroupGetPercpuStats
Extend virCgroupGetPercpuStats to fill in vcputime too
Rename id, max_id to need_cpus, total_cpus
Check maximum startcpu value correctly
Clean up virCgroupGetPercpuStats
