[libvirt] [PATCH] maint: Add support for .ctags.d
by Jiri Denemark
Depending on the way ctags was compiled, it may look for
.ctags.d/*.ctags files rather than .ctags for reading configuration.

[libvirt] Entering freeze for libvirt 5.4.0
by Daniel Veillard
This is tagged in git, I have put the signed tarball and source RPM at
the usual place:
https://libvirt.org/sources/
I did not build the binaries rpms, first it broke because I was still on F28
c.f. Jan's patch, and second it's true to provides little value, it's doubtful
people would just install my binaries as is. Will likely stick to sources
as part of releases in the future.
Release looks fine in my limited testing, https://ci.centos.org/view/libvirt/
is of a rare uniform green color, which is promising too !
Please give it a try, I will likely cut RC2 on Thrusday, and then
if everything goes fine push the GA over the w.e. or Monday,
thanks,
Daniel

[libvirt] Question about save and restore OVS per-port data in live migration
by wangxin (U)
Hi
When we try to migrate a guest with 12 NICs, we find libvirt will try
to get per-port data in finish phase, it makes the guest paused for
several hundred milliseconds.
qemuMigrationCookieAddNetwork
-> virNetDevOpenvswitchGetMigrateData for per-nic
-> run 'ovs-vsctl --if-exists get Interface vnetx external_ids:Port' (about 25ms)
In our case, there's no portData available and it seems there is no need to run the cmd.
Questions:
1. Is it necessary to get/set per-port data in migration finish phase? It will increase the downtime.
2. Is there any way (i.e. a switch) to not run the OVS cmd if there's no portData available?

[libvirt] [PATCH 0/9] util/resctrl cleanups and refactors
by Wang Huaqiang
Plan to support Resctrl Control Monitors, which is a feature introduced
by kernel 'resctrl' sub-model. Submit some cleanup and refactoring patches
for upcoming memory bandwidth resource monitoring (MBM) monitors.
Related MBM RFC is
https://www.redhat.com/archives/libvir-list/2019-April/msg01409.html.
This RFC is not actively discussed since libvirt already implemented similar
resctrl cache monitoring (CMT), and lots details have been discussed
and implemented during the work of CMT.
The cleanups and refactoring includes:
1. Removing some reluctant lines and white spaces that is existing
in current code and not meet the libvirt coding style.
2. Replace 'virResctrlAllocIsEmpty' with @n==0 for indicating no
resctrl allocation in configuration file.
3. Private API changes, removed 'virResctrlMonitorGetCacheOccupancy'
and exported a new API named 'virResctrlMonitorGetStats' with similar
functionality, but with capability to be used for retrieving MBM
statistical information.
4. Refactoring 'virResctrlMonitorFreeStats' for more reusing in code.
5. Extend data structure 'virResctrlMonitorStats' with the capability
to carry multiple statistical information from monitor.
Wang Huaqiang (9):
conf: code cleanup, remove empty line and one space
conf: code cleanup for return error code directly
conf: check if vcpus matches with any 'existing' allocaiton
conf: Replace 'virResctrlAllocIsEmpty' with @n==0 for indicating no
resctrl allocation in configuration file
conf: refactor 'virDomainResctrlVcpuMatch'
util: Refactor 'virResctrlMonitorFreeStats'
util: Refactor 'virResctrlMonitorStats'
util: Extend virresctl API to retrieve multiple monitor statistics
util: Remove unused virResctrlMonitorGetCacheOccupancy

[libvirt] [PATCH v2] qemu: aquire job in qemuDomainDefineXMLFlags
by Nikolay Shirokovskiy
The function updates vm->newDef and frees previous pesistent definition
which can be used by in different thread by some API that unlocks domain
to communicate to qemu. So we have an access to freed memory in that
thread. Let's acquire job condition in case of updating exiting domain.

[libvirt] [PATCH v2 0/2] introduction of version attribute for VFIO live migration
by Yan Zhao
This patchset introduces a version attribute under sysfs of VFIO Mediated
devices.
This version attribute is used to check whether two mdev devices are
compatible.
user space software can take advantage of this version attribute to
determine whether to launch live migration between two mdev devices.
Patch 1 defines version attribute in Documentation/vfio-mediated-device.txt
Patch 2 uses GVT as an example to show how to expose version attribute and
check device compatibility in vendor driver.
v2:
1. renamed patched 1
2. made definition of device version string completely private to vendor
driver
3. abandoned changes to sample mdev drivers
4. described intent and usage of version attribute more clearly.
