[libvirt] [PATCH 0/4] Add support for reboot-timeout
by Martin Kletzander
This series introduces simple reboot timeout support. That means what
should be done in case all boot options fail, reboot or not. And if
yes, then how long the machine should wait.
Before adding the support for that into XML parser, builder, and qemu,
I felt the need to cleanup the boot parsing and enums (I couldn't look
at that), so that's the first patch. Most of it is mechanical, the
rest should be pretty straight-forward.
---
I'd *love* to have it in 0.10.2, but I understand if it's too late :(

[libvirt] [PATCH] Ensure existing selinux mount is removed before mounting new one in LXC
by Daniel P. Berrange
Some kernel versions (at least RHEL-6 2.6.32) do not let you over-mount
an existing selinuxfs instance with a new one. Thus we must unmount the
existing instance inside our namespace.

[libvirt] [PATCH] build: avoid non-portable byte-swapping
by Eric Blake
Commit 0fc89098 used functions only available on glibc, completely
botched 32-bit environments, and risked SIGBUS due to unaligned
memory access on platforms that aren't as forgiving as x86_64.
* bootstrap.conf (gnulib_modules): Import ffsl.
* src/util/bitmap.c (includes): Use <strings.h> for ffsl.
(virBitmapNewData, virBitmapToData): Avoid 64-bit assumptions and
non-portable functions.
---
I wish I could push this under the build-breaker rule, but it is
not quite trivial enough.

[libvirt] [PATCH v4 0/9] improve virBitmap
by Hu Tao
In many places we store bitmap info in a chunk of data
(pointed to by a char *), and have redundant codes to
set/unset bits. This series extends virBitmap, and convert
those codes to use virBitmap.
changes:
v4:
- rename virBitmapAlloc to virBitmapNew
- rename virBitmapAllocFromData to virBitmapNewData
v3:
- renaming member variables of virBitmap
- rewrite virBitmapFormat using virBitmapNextSetBit
- store bits in machine native endian format
- more tests of virBitmap
v2:
- fix bug in qemuSetupCgroupForEmulator
- new function virBitmapNextSetBit
- virBitmapcmp -> virBitmapEqual
- virBitmap: store bits in little endian format
- some improvements of virBitmap
- fix some memory leaks
Hu Tao (9):
bitmap: new member variable and function renaming
New functions for virBitmap
use virBitmap to store cpupin info
use virBitmap to store cpu affinity info
use virBitmap to store numa nodemask info.
use virBitmap to store cpumask info.
use virBitmap to store cells' cpumask info.
use virBitmap to store nodeinfo.
remove virDomainCpuSetFormat and virDomainCpuSetParse

[libvirt] [PATCH 0/5] Support ephemeral passthrough hostdevs
by Shradha Shah
The ephemeral flag helps support migration with PCI-passthrough.
An ephemeral hostdev is automatically unplugged before migration
and replugged (if one is available on the destination) after
migration.
Shradha Shah (5):
Added ephemeral flag for hostdev in domain conf.
Adding ephemeral flag for hostdev in network conf.
Ephemeral flag mofication within the network driver.
Ephemeral flag modification within the qemu driver.
Migration support for ephemeral hostdevs.

[libvirt] [PATCH] Fix minor details in apic eoi
by Martin Kletzander
The introduction of APIC EOI patches had a few little details that
could look better, so this patch fixes that.
The fixes:
- "on" and "off" as values are changed to <code>on</code> and
<code>off</code> respectively, because the code around uses the
same tags for such values.
- VIR_FREE is unnecessary as it is done in the error handling as well
- one empty line stayed in my local changes not included in the sent
patch, the code around is separated in similar fashion
- For const strings, virBufferAddLit should be used instead of
virBufferAsprintf.
