[libvirt] [tck PATCH] eliminate use of deprecated brctl in network tests
by Laine Stump
brctl is part of the bridge-utils package, which has been deprecated /
replaced by the "ip" and "bridge" commands in the iproute package in
all modern distros. This patch removes the few usages of brctl in
libvirt-tck's network tests, replacing it with a functional equivalent
that uses "ip link show type bridge" instead.

[libvirt] [PATCH] api,qemu: add block latency histogram
by Nikolay Shirokovskiy
This patch adds option to configure/read latency histogram of
block device IO operations. The corresponding functionality
in qemu still has x- prefix AFAIK. So this patch should
help qemu functionality to become non experimental.
In short histogram is configured thru new API virDomainSetBlockLatencyHistogram and
histogram itself is available as new fields of virConnectGetAllDomainStats
output.

[libvirt] [PATCH v7] qemu: Introduce state_lock_timeout to qemu.conf
by Yi Wang
When doing some job holding state lock for a long time,
we may come across error:
"Timed out during operation: cannot acquire state change lock"
Well, sometimes it's not a problem and users want to continue
to wait, and this patch allow users decide how long time they
can wait the state lock.
Signed-off-by: Yi Wang <wang.yi59(a)zte.com.cn>
Reviewed-by: Xi Xu <xu.xi8(a)zte.com.cn>
---
changes in v7:
- fix multiplication issue in BeginJobInternal
changes in v6:
- modify the description in qemu.conf
- move the multiplication to BeginJobInternal
changes in v5:
- adjust position of state lock in aug file
- fix state lock time got from conf file from milliseconds to
seconds
changes in v4:
- fix syntax-check error
changes in v3:
- add user-friendly description and nb of state lock
- check validity of stateLockTimeout
changes in v2:
- change default value to 30 in qemu.conf
- set the default value in virQEMUDriverConfigNew()

[libvirt] [PATCH] tests: Follow up on qemucaps2xmldata rename

The directory has been renamed in 562990849a9d, but a
reference to it was not updated at the same time, causing
'make dist' to fail ever since. Fix it.

[libvirt] [PATCH 0/5] qemu: Detect KVM usability correctly
by Andrea Bolognani
There are a few cases in which we're not reporting the correct
information through 'virsh capabilities', leading to applications
such as libguestfs attempting to launch KVM guests on a host that
doesn't actually support them.
Our code is also more complicated than it needs to be due to
backwards compatibilty reasons that we no longer care about these
days, so we can perform some cleanup there; there are further
cleanup opportunities in the same area, but some of them are a
bit tricky so I'll leave them for a follow-up series.
We also get some extra test coverage pretty much for free. Yay!
Andrea Bolognani (5):
tests: Reuse qemucapabilities data for qemucaps2xml
tests: Add more tests to qemucaps2xml
qemu: Drop QEMU_CAPS_ENABLE_KVM
qemu: Clarify QEMU_CAPS_KVM
qemu: Don't check for /dev/kvm presence

[libvirt] [PATCHv2 0/6] Introduce syntax-check rule for incorrect indentation and blank first line in function body
by Shi Lei
v1 here:
https://www.redhat.com/archives/libvir-list/2018-September/msg00497.html
Diff from v1: (according to the comments from Jano)
- Change build-aux/check-spacing.pl rather than cfg.mk
- Don't exempt '/' (which matches comments in function) in the rule
- Split these two type of error messages and only output the relevant one
- Patch 2/4 of v1 divide into two patches by the type of error messages
Shi Lei (6):
build-aux:check-spacing.pl: Introduce syntax-check rule for incorrect
indentation and blank first line in function body
src: fix incorrect indentation in function body by checking first line
tests: fix incorrect indentation in function body by checking first
line

[libvirt] [PATCH 0/5] Use memfd if possible
by marcandre.lureau＠redhat.com
From: Marc-André Lureau <marcandre.lureau(a)redhat.com>
Hi,
This is an alternative to "[RFC v2 02/16] qemu: add memfd memory
backing", which added a new source type. Instead, Daniel suggested to
automatically use memfd for anonymous memory when available.
Marc-André Lureau (5):
qemu: add memory-backend-memfd capability check
qemu: check memory-backend-memfd.hugetlb capability
qemu: prefer memfd for anonymous memory
conf: drop hugepage non-anoymous memory requirement
tests: add qemuxml2argv memfd-memory-numa test

[libvirt] [PATCH] libxl: remove configure check for libxl_domain_config_from_json
by Jim Fehlig
The libxl_domain_config_from_json API appeared in Xen 4.5, hence
there is no need to check for its existence after changing the
minimum supported Xen version to 4.6. Remove the check and its
use in the tests.
