[libvirt] [PATCH] virutil: Provide non-linux impl for virGetFCHostNameByFabricWWN
by Michal Privoznik
Currently, there's only linux implementation for
virGetFCHostNameByFabricWWN(). Since the symbol is exported in
our private symbols we ought to have implementation for other
platforms too. This also triggers compilation error on FreeBSD:
../src/.libs/libvirt_driver_storage_impl.a(libvirt_driver_storage_impl_la-storage_backend_scsi.o): In function `createVport':
/usr/home/jenkins/libvirt-master/systems/libvirt-freebsd/build/src/../../src/storage/storage_backend_scsi.c:740: undefined reference to `virGetFCHostNameByFabricWWN'

Ouch. I simply removed patches 3/4 and 4/4 from the series, and
didn't notice there was a mistake in patch 1/2 corrected by patch
4/4 in v1. I will fix it and send v3, sorry for the noise.

[libvirt] [PATCH v2 0/2] Allow migration with invtsc if TSC frequency is explicitly set
by Eduardo Habkost
This series makes QEMU accept migration if tsc-frequency is
explicitly set on configuration. As management software is
required to keep device configuration the same on migration
source or destination, explicit tsc-frequency will ensure that
either:
* The destination host has a matching TSC frequency; or
* The destination host has TSC scaling available.
Changes series v1 -> v2
=======================
* v1 series subject was:
* [PATCH 0/4] Allow migration with invtsc if there's no
frequency mismatch
* Removed patches 3/4 and 4/4, that allowed migration
if no explicit tsc-frequency was set. Implementing the check on
post_load or post_init is not enough to make migration abort,
so we will need a more complex solution to implement that
feature.
Plans for future work
=====================
1) Querying host TSC frequency/scaling capability
-------------------------------------------------
I plan to include TSC frequency/scaling information on
query-cpu-model-expansion model="host" in a future series. Then
management software will be able to automatically configure TSC
frequency when invtsc is enabled, instead of requiring the user
to configure it explicitly. While we don't implement that, invtsc
migration will be possible only if the user configures TSC
frequency manually.
2) invtsc migration with no explicit TSC frequency
--------------------------------------------------
A future series can implement migration when TSC frequency is not
specified explicitly. It will be a bit more complex because it
requires either letting the destination abort the migration, or
sending TSC frequency/scaling information from destination to
source.

[libvirt] Regarding Migration Code
by Anubhav Guleria
Greetings,
I was trying to understand the flow of Migration Code in libvirt and
have few doubts:
1) libvirt talks to QEMU/KVM guests via QEMU API. So overall, in
order to manage QEMU/KVM guests I can either use libvirt (or tools
based on libvirt like virsh) or QEMU monitor. Is it so?
2) Since libvirt is Hypervisor neutral so actual migration
algorithm(precopy or postcopy) is present in the hypervisor ,i.e. in
case of QEMU it should be present in QEMU code base . I was going
through the code starting from libvirt-domain api and not able to
follow after virDomainMigrateVersion3Full(.....) . Kindly help.
3) I want to determine the Migration
Time, Downtime and other resource usage.
What is the correct way to determine the same? Should I use libvirt
API or directly virsh or something else? Which is fast and efficient
way for the same?
Thanks in advance. And sorry if that was too basic

[libvirt] [PATCH v2 0/4] Allow creation of vHBA by parent_wwnn/wwpn or fabric_name
by John Ferlan
v1: http://www.redhat.com/archives/libvir-list/2016-November/msg00866.html
Based on ACKs some of the v1 changes were pushed to make this series
appear shorter.
Changes since v1
- Patch 1 (formerly patch 4)
Rather than separate XML elements, use the existing <parent> and just
make attributes for wwnn, wwpn, and fabric_wwn. The parent element can
now be string text or empty.
Added checked for if either wwnn/wwpn provided, then the other is too.
- Patch 2 (formerly patch 5)
No changes, but no formal ACK either
- Patch 3 (formerly patch 10)
Rather than READ_WWN macro across two functions, I created a helper
function to read and compare the various wwn values (wwnn, wwpn, and
fabric_wwn).
John Ferlan (4):
nodedev: Add the ability to create vHBA by parent wwnn/wwpn or
fabric_wwn
conf: Add more fchost search fields for storage pool vHBA creation
util: Introduce virGetFCHostNameByFabricWWN
iscsi: Add parent wwnn/wwpn or fabric capability for createVport

[libvirt] [PATCH v2] libxl: define a per-domain logger.
by Cédric Bosdonnat
libxl doesn't provide a way to write one log for each domain. Thus
we need to demux the messages. If our logger doesn't know to which
domain to attribute a message, then it will write it to the default
log file.
Starting with Xen 4.9 (commit f9858025 and following), libxl will
write the domain ID in an easy to grab manner. The logger introduced
by this commit will use it to demux the libxl log messages.
Thanks to the default log file, this logger will also work with older
versions of Xen.

[libvirt] [PATCH 0/9] More event handling support
by Daniel P. Berrange
This series adds suppoort for more events
- Event when <metadata> in a domain changes
- Event when virSecret are created/deleted
- Event when virSecret value is changed
The latter two of course required wiring up the secret object
for event support, since we've not had secret events before
now.
Daniel P. Berrange (9):
Add domain event for metadata changes
Introduce secret lifecycle event APIs
conf: add secret event handling
conf: simplify internal virSecretDef handling of usage
remote: implement secret lifecycle event APIs
secret: add support for lifecycle events
examples: add secret events to event demo program
virsh: add secret lifecycle event handling
secret: add support for value change events
