[libvirt PATCH] schema: Add support for high TSC frequency
by Jiri Denemark
The unsignedInt XML schema type allows for values up to 2^32 - 1, i.e.,
using 4294967296 or greater TSC frequency would fail schema validation.

[PATCH v2] qemu: Move qemuExtDevicesStop() before removing the pidfiles
by Masayoshi Mizuma
From: Masayoshi Mizuma <m.mizuma(a)jp.fujitsu.com>
A qemu guest which has virtiofs config fails to start if the previous
starting failed because of invalid option or something.
That's because the virtiofsd isn't killed by virPidFileForceCleanupPath()
on the former failure because the pidfile was already removed by
virFileDeleteTree(priv->libDir) in qemuProcessStop(), so
virPidFileForceCleanupPath() just returned.
Move qemuExtDevicesStop() before virFileDeleteTree(priv->libDir) so that
virPidFileForceCleanupPath() can kill virtiofsd correctly.
For example of the reproduction:
# virsh start guest
error: Failed to start domain guest
error: internal error: process exited while connecting to monitor: qemu-system-x86_64: -foo: invalid option
... fix the option ...
# virsh start guest
error: Failed to start domain guest
error: Cannot open log file: '/var/log/libvirt/qemu/guest-fs0-virtiofsd.log': Device or resource busy

[libvirt] [PATCH v2 00/13] virsh completion improvement
by Lin Ma
Add more bash completions for some of virsh subcommands/subparameters.
v1->v2
* Follow Michal's suggestions:
- guestvcpus command: complete offlined vCPUs if --enable, complete onlined vCPUs if --disable
- Added a static helper function for interface string provider,
- Adjusted some needlessly complicated loops.
* Refered to Peter and Michal's comments, I droped the vnc completion patches.
* Concentrate on completion itself, Drop all of patches which related to macros to make review easier.
Lin Ma (13):
virsh: Add vcpu list completion to guestvcpus command
virsh: Add logical CPU IDs completion for nodecpustats command
virsh: Add serial/parallel device name completion to console command
virsh-interface: Add a static helper virshInterfaceStringHelper
virsh: Add interface mac completion to iface-name command
virsh: Add interface name completion to iface-bridge command
virsh: Add interface name completion to iface-mac command
vsh: Fix completion error in case of multiple mac addresses
virsh: Add mac completion to net-dhcp-leases command
virsh: Move/add some of function declarations to virsh-domain.h
virsh: Add signal name completion to send-process-signal command
virsh: Add lifecycle type completion to set-lifecycle-action command
Add lifecycle action completion to set-lifecycle-action command

[libvirt PATCH] virgdbus: fix getting non-shared DBus connection
by Pavel Hrdina
We need to pass some flags in order to properly initialize the
connection otherwise it will not work. This copies what GLib does
for g_bus_get_sync() internally.
This fixes an issue with LXC driver where libvirt was not able to
register any VM with machined.
