[libvirt] [PATCH 0/4] Add ability to store and display notes and description with domains
by Peter Krempa
This patchset adds ability to store, display and modify comments for domains to help
administrators identify and store metadata to domains to allow easy identification.
A short description "note" was added as an attribute for the <description> element
to hold a shorter description (limited to max 40 characters) to be shown along with
lists of domains.
A new command is being added to virsh to accomodate work with these new options.
Peter Krempa (4):
xml: Add attribute to <description> element to hold a short note
api: Add api to set domain note and description in runtime
qemu: Implement note API in qemu driver
virsh: Add support for modifying domain description and notes

[libvirt] [PATCH] virsh domiflist: change output
by Taku Izumi
When using "virsh domifstat" command or "virsh domiftune" command,
we pass an interface name as a parameter, so interface name is
important.
"virsh domiflist" output should display interface names
on the first row.

[libvirt] [PATCH] qemu: Introduce inactive PCI device list
by Osier Yang
pciTrySecondaryBusReset checks if there is active device on the
same bus, however, qemu driver doesn't maintain an effective
list for the inactive devices, and it passes meaningless argment
for parameter "inactiveDevs". e.g. (qemuPrepareHostdevPCIDevices)
if (!(pcidevs = qemuGetPciHostDeviceList(hostdevs, nhostdevs)))
return -1;
...skipped...
if (pciResetDevice(dev, driver->activePciHostdevs, pcidevs) < 0)
goto reattachdevs;
NB, the "pcidevs" used above are extracted from domain def, and
thus one won't be able to attach a device of which bus has other
device even detached from host (nodedev-detach). To see more
details of the problem:
RHBZ: https://bugzilla.redhat.com/show_bug.cgi?id=773667
This patch is to resolve the problem by introduce an inactive
PCI device list (just like qemu_driver->activePciHostdevs), and
the whole logic is:
* Add the device to inactive list when do nodedev-dettach
* Remove the device from inactive list when do nodedev-reattach
* Remove the device from inactive list when do attach-device
(for not managed device)
* Add the device to inactive list after detach-device, only
if the device is not managed
* Don't do any work if the device is managed, as it manages
there is no gap in the whole workflow for another guest
who wants to
With above, we have sufficient inactive PCI device list, and thus
we can use it for pciResetDevice. e.g.(qemuPrepareHostdevPCIDevices)
if (pciResetDevice(dev, driver->activePciHostdevs,
driver->inactivePciHostdevs) < 0)
goto reattachdevs;

[libvirt] [PATCH v2] qemu: Support copy on read for disk
by Osier Yang
The new introduced optional attribute "copy_on_read</code> controls
wether to copy read backing file into the image file. The value can
be either "on" or "off". Copy-on-read avoids accessing the same backing
file sectors repeatedly and is useful when the backing file is over a
slow network. By default copy-on-read is off.

[libvirt] [PATCH] build: silence some compiler warnings from gnulib
by Eric Blake
Gnulib claims that there are some classes of warnings that are
worth enabling during development, but where silencing those
warnings causes code bloat that is not necessary in an optimized
build. The code bloat to silence the warnings is only enabled
by -Dlint. Follow the lead of coreutils in setting up -Dlint
whenever full warnings are requested.
* m4/virt-compile-warnings.m4 (LIBVIRT_COMPILE_WARNINGS): Add
-Dlint, and move _FORTIFY_SOURCE to config.h instead of CFLAGS.
---
In particular, see this gnulib thread, where Dan Berrange complained
about a warning present on a mingw cross-compile:

[libvirt] [PATCH v2 1/1] Added check for maximum number of vcpus exceeding topology limit
by Martin Kletzander
Earlier, when the number of vcpus was greater than the topology allowed,
libvirt didn't raise an error and continued, resulting in running qemu
with parameters making no sense. Even though qemu did not report any
error itself, the number of vcpus was set to maximum allowed by the
topology.

[libvirt] ANNOUNCE: Release of libvirt-sandbox version 0.0.2
by Daniel P. Berrange
I pleased to announce the first public release of libvirt-sandbox,
version 0.0.2 is now available for download
ftp://libvirt.org/libvirt/sandbox/
The packages are GPG signed with
Key fingerprint: DAF3 A6FD B26B 6291 2D0E 8E3F BE86 EBB4 1510 4FDF (4096R)
The libvirt-sandbox package provides an API layer on top of libvirt-gobject
which facilitates the cration of application sandboxes using virtualization
technology. An application sandbox is a virtual machine or container that
runs a single application binary, directly from the host OS filesystem.
In other words there is no separate guest operating system install to build
or manager.
At this point in time libvirt-sandbox can create sandboxes using either LXC
or KVM, and should in theory be extendable to any libvirt driver. The first
release is able to run simple command line based programs. While there is
some GUI support, this is mostly unreliable / non-functional at this point
in time, future releases will address this properly.
Some examples

berrange 48 0.0 0.0 13124 996 pts/1 R+ 22:31 0:00 \_ ps -axuwf
Watch this space, there is much more interesting functionality in this
space that will be arriving soon...
Feedback / patches / etc should be directed to the main libvirt
development mailing list.
Regards,
Daniel
