[libvirt] memory ballooning and nova
by Raymond Durand
Is Libvirt memory ballooning managed by nova in OpenStack Juno?
Is Libvirt memory ballooning independent from the OpenStack "RAM
allocation ratio"? and allow a VM to expand (page out) even though the
overall RAM allocation ratio is already at his maximum?
Thanks,

[libvirt] [PATCH 0/3] libxl: a few minor patches
by Jim Fehlig
This series contains a few simple changes to the libxl driver.
Patches 1 and 2 were included in
https://www.redhat.com/archives/libvir-list/2015-February/msg00611.html
To make an upcoming V2 of that series easier to review, I removed the
mostly unrelated patches and include them here, along with one other
small fix.
Jim Fehlig (3):
libxl: remove redundant calls to libxl_evdisable_domain_death
libxl: use libxl_ctx passed to libxlConsoleCallback
libxl: remove unneeded cleanup_unlock label

[libvirt] [libvirt-python PATCH 0/2] Python bindings for IOThreads
by John Ferlan
Going along with the recent libvirt IOThreads API additions, here's the
Python patches... These would only be submitted once the libvirt code
goes in... See the following for the libvirt patches:
http://www.redhat.com/archives/libvir-list/2015-February/msg00593.html
Reviewer's NOTE:
- Alternatively to the error from patch 1, I could modify the code to
not fail on <= 0, but rather just < 0 with the result being the following
for a domain without IOThreads configured:
$ python iothr.py
[]
$
Instead of:
Traceback (most recent call last):
File "iothr.py", line 6, in <module>
print dom2.getIOThreadsInfo()
File "/usr/lib64/python2.7/site-packages/libvirt.py", line 1197, in getIOThreadsInfo
if ret is None: raise libvirtError ('virDomainGetIOThreadsInfo() failed', dom=self)
libvirt.libvirtError: virDomainGetIOThreadsInfo() failed

[libvirt] [PATCH v3 0/9] Introduce display of IOThreads Information
by John Ferlan
v2 here:
http://www.redhat.com/archives/libvir-list/2015-February/msg00562.html
Changes over v2:
Patches 1-4
* Add "resources" and "nresources" in order to return the resources that
are using an IOThread
* Fixed memory leak - neglected to free the qemuMonitorIOThreadsInfoPtr
'iothreads' in patch 3
Patches 5-9 (NEW)
* Patches 5 & 6 implement the API/remote protocol for virDomainSetIOThreads
* Patch 7 implements a couple of helper function - copies of existing
vcpupin functions
* Patch 8 implements the qemu backend qemuDomainSetIOThreads in order to
allow setting IOThread pin data either for live or config. Heavily lifted
from existing vcpu code
* Patch 9 implements the virsh command options in order to set the pinning
on a specific thread. As a side effect/benefit one can now display just one
IOThread if so desired.
All the changes are sufficient to satisfy the following bz:
https://bugzilla.redhat.com/show_bug.cgi?id=1135491
John Ferlan (9):
Implement public API for virDomainGetIOThreadsInfo
remote: Implement the remote plumbing for virDomainGetIOThreadsInfo
qemu: Implement the qemu driver fetch for IOThreads
virsh: Add 'iothreads' command
Implement public API for virDomainSetIOThreads
remote: Implement remote plumbing for virDomainSetIOThreads
domain: Introduce virDomainIOThreadsPin{Add|Del}
qemu: Add qemuDomainSetIOThreads
virsh: Allow setting of the iothread pin

[libvirt] [PATCH 00/10] A bunch of extensions to libxl driver
by Marek Marczykowski-Górecki
This are some additional features to libxl driver. Some of them require change
in domain config structures/syntax. Details described with each patch.
Actually this is next iteration of a few years old patch series...
Marek Marczykowski-Górecki (10):
libxl: update dom->id in libxlDomainCreateWithFlags
conf: support backend domain name in disk and network devices
libxl: support backend domain setting for disk and net devices
libxl: fill HVM SDL and VNC settings based on <graphics/> entries
libxl: pass ipaddr to libxl toolstack
libxl: add tablet/mouse input device support
libxl: prevent attaching multiple netdevs with the same MAC
libxl: support domain config modification in virDomainRestoreFlags
libxl: stubdom emulator type
tests: add some simple libxl XML->XML tests

At least Xen supports backend drivers in another domain (aka "driver
domain"). This patch introduces XML config option for such setting as
'domain' attribute of 'source' element. Verification its content is left
for the driver.
In the future same option will be needed for USB devices (hostdev
objects), but for now libxl doesn't have support for PVUSB.

Changes in v2:
- describe in docs/formatdomain.html.in
- enforce empty domain tag (only 'name' attribute allowed)
Changes in v3:
- change <domain name='xx'/> element to domain='' attribute of source
element - this is more logical place
- grammar of docs

This implement handling of <source domain=''/> parameter introduced in
previous patch.
Lookup on domain name (to get domain ID) requires libxlDriverPrivate
object, so it must be passed down to libxlMakeDisk and libxlMakeNet from
top level callers.

Changes in v2:
- rebase on 1.0.6+
- fix indentation
- make libxl_name_to_domid switch more defensive
Changes in v3:
- rebase on 1.2.12+
- leave name->XID resolution to libxl itself, which greatly simplify
the code (but requires Xen at least 4.3)

Subject: [PATCH 04/10] libxl: fill HVM SDL and VNC settings based on <graphics/> entries
Date: Thu, 5 Feb 2015 06:17:10 +0100

Vfb entries in domain config are used only by PV drivers. Qemu
parameters are build based on b_info struct. So fill it with the same
data as vfb entries (actually the first one).
This will additionally allow graphic-less domain, when no <graphics/>
entries are present in domain XML (previously VNC was always enabled).

There was a discussion about calling virDomainDefCheckABIStability. The use
case I have for this is to start multiple domains from the same savefile. This
require changing:
- UUID
- name
- IP address
Those are exactly type of changes blocked by virDomainDefCheckABIStability.
Perhaps some "permissive" mode should be introduced to the
virDomainDefCheckABIStability function?

Xen have feature of having device model in separate domain (called stub
domain). Add a 'type' attribute to 'emulator' element to allow selecting
such a configuration. Emulator path is still used for qemu running in dom0 (if
any). Libxl currently do not allow to select stubdomain path.

I think it would be good idea to introduce the same change to capabilities XML.
The problem is I can't include domain_conf.h from capabilities.h, so probably
that enum declaration needs to be moved to capabilities.h. Is it the right way?
Or it should be done somehow different?

[libvirt] [PATCH] domain_conf: Format <pvpanic/> without address correctly
by Michal Privoznik
We have something like pvpanic device. However, in some cases it does
not have any address assigned, in which case we produce this ugly XML
(still valid though):
<devices>
<emulator>/usr/bin/qemu</emulator>
...
<panic>
</panic>
</devices>
Lets format "<pvpanic/>" instead.

[libvirt] [PATCH] conf: Remove duplicate entries in <metadata> by namespace
by Peter Krempa
Since the APIs support just one element per namespace and while
modifying an element all duplicates would be removed, let's do this
right away in the post parse callback.

[libvirt] [PATCH 0/3] unify memtune value representation in libvirt
by Pavel Hrdina
The first patch rewrites virsh memtune command to accept 0 as valid value
instead of ignoring it.
In the second patch I'll introduce a simple helper to crop the *_limit values
to VIR_DOMAIN_MEMORY_PARAM_UNLIMITED as its used several times while reading
values from cgroups.
The last patch actually changes the internal representation of unlimited memtune
settings. More detailed description is in commit message. My motivation to
change it completely is to prevent future bugs with those limits.
Pavel Hrdina (3):
virsh: fix memtune to also accept 0 as valid value
virutil: introduce helper to set memory limits
memtune: change the way how we store unlimited value
