[libvirt] [PATCH] qemu: expand domain memory statistics with 'last-update' timestamp
by Derbyshev Dmitriy
From: Derbyshev Dmitry <dderbyshev(a)virtuozzo.com>
QEMU reports timestamp along with other memory statistics, but this information is not saved into domain statistics.
It could be useful to determine if the data reported is fresh or not.
Balloon statistics are not reported in hrf, so no modifications are made in qemu_monitor_text.c.

[libvirt] [PATCH 0/3] Do not check for domain liveness in virDomainObjSetDefTransient
by Ján Tomko
virDomainObjSetDefTransient has an unintuitive attribute 'live':
when set to 'true', it ignores the virDomainObjIsActive test.
The most common usage is on domain startup, where most of the callers
want to create a transient definition even though the domain is not
yet active.
The only place where live=false is still required is
virDomainObjGetPersistentDef (and its usage could possibly be cleaned
up too, since it's only called in the drivers that already do SetDefTransient
on domain startup).
Split out the virDomainObjIsActive check into virDomainObjGetPersistentDef
and remove it for the rest of the callers along with the 'live' attribute.
Ján Tomko (3):
Clean up redundant usage of virDomainObjSetDefTransient
Check if the domain is active in virDomainObjGetPersistentDef
Do not check for domain liveness in virDomainObjSetDefTransient

[libvirt] [PATCH v5 0/2] qemu: Support for QXL heads
by Martin Kletzander
v5:
- Just a rebase, plus v4 had some hunk in that didn't belong there so
this one's cleaner to look at
- https://www.redhat.com/archives/libvir-list/2016-March/msg01436.html
v4:
- Added test case without "heads="
- Don't consolidate 'size_t i, j' declarations
v3:
- rebase on top of current master in order to cleanly apply
- https://www.redhat.com/archives/libvir-list/2016-March/msg01198.html
v2:
- don't change heads when migrating
- https://www.redhat.com/archives/libvir-list/2016-March/msg00811.html
v1:
- https://www.redhat.com/archives/libvir-list/2016-March/msg00410.html

[libvirt] [PATCH v3 0/2] Add support for zero-write detection
by Martin Kletzander
v3:
- I know Peter said he'll review it, but there are conflicts every
once in a while, so rebased version will apply cleanly for a while
- And it's actually not that big of a change to wait for some bigger
things to be designed, I believe =)
- https://www.redhat.com/archives/libvir-list/2016-April/msg01926.html
v2:
- use 'zeroes' instead of 'zeros'
- https://www.redhat.com/archives/libvir-list/2016-February/msg01146.html

After these regular errors, I still cannot build cleanly:

^~~~~~~
cc1: all warnings being treated as errors
These are obviously false positives. I know some developers here
are not very fond of fixing those, so my question is - is it
worth the effort or will my patches be NACKed straight away?

[libvirt] [PATCH] conf: Skip MAC checks when using an auto-generated one during detach-device
by Kothapally Madhu Pavan
When we try to detach a network device without specifying the
mac address, random mac address is generated. As the generated
mac address will not be available in the running vm, detaching
device will fail erroring out "error: operation failed: no
device matching mac address xx:xx:xx:xx:xx:xx found".
This patch allows to match DetachDeviec xml using PCI address
when mac address is not specified.
