* docs/ChangeLog.xsl docs/newapi.xsl docs/site.xsl: change all
stylesheets to output UTF-8 HTML instead of ISO Latin 1 which was
breaking on some people names.
Fix this warning, there is no need to use an intermediate,
different array pointer.
network.c: In function 'getIPv6Addr':
network.c:50: warning: dereferencing type-punned pointer will break strict-aliasing rules
* src/util/network.c: avoid an intermediary pointer cast
* src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h: Add callbacks
for reset, shutdown, poweroff and stop events. Add convenience
methods for emiting those events
With addition of events there will be alot of callbacks.
To avoid having to add many APIs to register callbacks,
provide them all at once in a big table
* src/qemu/qemu_driver.c: Pass in a callback table to QEMU
monitor code
* src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h Replace
the EOF and disk secret callbacks with a callback table
Initial support for the new QEMU monitor protocol using JSON
as the data encoding format instead of plain text
* po/POTFILES.in: Add src/qemu/qemu_monitor_json.c
* src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Hack to turn on QMP
mode. Replace with a version number check on >= 0.12 later
* src/qemu/qemu_monitor.c: Delegate to json monitor if enabled
* src/qemu/qemu_monitor_json.c, src/qemu/qemu_monitor_json.h: Add
impl of QMP protocol
* src/Makefile.am: Add src/qemu/qemu_monitor_json.{c,h}
Now that drivers are using a private domain object state blob,
the virDomainObjFormat/Parse methods are no longer able to
directly serialize all neccessary state to/from XML. It is
thus neccessary to introduce a pair of callbacks fo serializing
private state.
The code for serializing vCPU PIDs and the monitor device
config can now move out of domain_conf.c and into the
qemu_driver.c where they belong.
* src/conf/capabilities.h: Add callbacks for serializing private
state to/from XML
* src/conf/domain_conf.c, src/conf/domain_conf.h: Remove the
monitor, monitor_chr, monitorWatch, nvcpupids and vcpupids
fields from virDomainObjPtr. Remove code that serialized
those fields
* src/libvirt_private.syms: Export virXPathBoolean
* src/qemu/qemu_driver.c: Add callbacks for serializing monitor
and vcpupid data to/from XML
* src/qemu/qemu_monitor.h, src/qemu/qemu_monitor.c: Pass monitor
char device config into qemuMonitorOpen directly.
The code to start CPUs executing has nothing todo with CPU
affinity masks, so pull it out of the qemudInitCpuAffinity()
method and up into qemudStartVMDaemon()
* src/qemu/qemu_driver.c: Pull code to start CPUs executing out
of qemudInitCpuAffinity()
The current QEMU disk media change does not support setting the
disk format. The new JSON monitor will support this, so add an
extra parameter to pass this info in
* src/qemu/qemu_driver.c: Pass in disk format when changing media
* src/qemu/qemu_monitor.h, src/qemu/qemu_monitor.c,
src/qemu/qemu_monitor_text.c, src/qemu/qemu_monitor_text.h:
Add a 'format' arg to qemuMonitorChangeMedia()
The qemuMonitorEscape() method, and the VIR_ENUM for migration
status will be needed by the JSON monitor too, so move that code
into the shared qemu_monitor.c file instead of qemu_monitor_text.c
* src/qemu/qemu_monitor.h: Declare qemuMonitorMigrationStatus enum
and qemuMonitorEscapeArg and qemuMonitorEscapeShell methods
* src/qemu/qemu_monitor.c: Implement qemuMonitorMigrationStatus enum
and qemuMonitorEscapeArg and qemuMonitorEscapeShell methods
* src/qemu/qemu_monitor_text.c: Remove above methods/enum
If QEMU shuts down while we're in the middle of processing a
monitor command, the monitor will be freed, and upon cleaning
up we attempt to do qemuMonitorUnlock(priv->mon) when priv->mon
is NULL.
To address this we introduce proper reference counting into
the qemuMonitorPtr object, and hold an extra reference whenever
executing a command.
* src/qemu/qemu_driver.c: Hold a reference on the monitor while
executing commands, and only NULL-ify the priv->mon field when
the last reference is released
* src/qemu/qemu_monitor.h, src/qemu/qemu_monitor.c: Add reference
counting to handle safe deletion of monitor objects

This introduces simple API for handling JSON data. There is
an internal data structure 'virJSONValuePtr' which stores a
arbitrary nested JSON value (number, string, array, object,
nul, etc). There are APIs for constructing/querying objects
and APIs for parsing/formatting string formatted JSON data.
This uses the YAJL library for parsing/formatting from
http://lloyd.github.com/yajl/
* src/util/json.h, src/util/json.c: Data structures and APIs
for representing JSON data, and parsing/formatting it
* configure.in: Add check for yajl library
* libvirt.spec.in: Add build requires for yajl
* src/Makefile.am: Add json.c/h
* src/libvirt_private.syms: Export JSON symbols to drivers
Add a --system flag to autogen.sh which gets turned into the args
--prefix=/usr --sysconfdir=/etc --localstatedir=/var to make it
easy to build with settings that match an RPM build
* autogen.sh: Add --system flag
Some of the very useful calls for XML parsing provided by util/xml.[ch]
were not exported as private symbols. This patch fixes this.

Xen HVM guests with PV drivers end up with two network interfaces for
each configured interface. One of them being emulated by qemu and the
other one paravirtual. As this might not be desirable, the attached
patch provides a way for users to specify that only paravirtual network
interface should be presented to the guest.
The configuration was inspired by qemu/kvm driver, for which users can
specify model='virtio' to use paravirtual network interface.
The patch adds support for model='netfront' which results in
type=netfront instead of type=ioemu (or nothing for newer xen versions)
in guests native configuration. Xen's qemu ignores interfaces with
type != ioemu and only paravirtual network device will be seen in the
guest.
Four possible configuration scenarios follow:
- no model specified in domain's XML
- libvirt will behave like before this change; it will set
type=ioemu for HVM guests on xen host which is not newer than
XEND_CONFIG_MAX_VERS_NET_TYPE_IOEMU
- covered by existing tests
- PV guest, any model
- no functional change, model is passed as is (and ignored by the
hypervisor)
- covered by existing tests (e.g., *-net-e1000.*)
- HVM guest, model=netfront
- type is set to "netfront", model is not specified
- covered by new *-net-netfront.* tests
- HVM guest, model != netfront
- type is set to "ioemu", model is passed as is
- covered by new *-net-ioemu.* tests
The fourth scenario feels like a regression for xen newer than
XEND_CONFIG_MAX_VERS_NET_TYPE_IOEMU as users who had a model specified
in their guest's configuration won't see a paravirtual interface in
their guests any more. On the other hand, the reason for specifying a
model is most likely the fact that they want to use such model which
implies emulated interface. Users of older xen won't be affected at all
as their xen provides paravirtual interface regardless of the type used.
- src/xen/xend_internal.c: add netfront support for the xend backend
- src/xen/xm_internal.c: add netfront support for the XM serialization too
Also fixed serial port configuration which was broken due to recent
change in virDomainChrDef where targetType was newly added.
* src/Makefile.am: add new files
* src/vbox/vbox_driver.c: add case for version 3.1
* src/vbox/vbox_tmpl.c: refactor common patterns into macros, support for

esxVMX_IndexToDiskName handles indices up to 701. This limit comes
from a mapping gap in virDiskNameToIndex:
sdzy -> 700
sdzz -> 701
sdaaa -> 728
sdaab -> 729
This line in virDiskNameToIndex causes this gap:
idx = (idx + i) * 26;
Fixing it by altering this line to:
idx = (idx + (i < 1 ? 0 : 1)) * 26;
Also add a new version of virIndexToDiskName that handles the inverse
mapping for arbitrary indices.
* src/esx/esx_vmx.[ch]: remove esxVMX_IndexToDiskName
* src/util/util.[ch]: add virIndexToDiskName and fix mapping gap
* tests/esxutilstest.c: update test to verify that the gap is fixed
* src/conf/domain_conf.c: don't call virDomainObjUnlock twice
* src/qemu/qemu_driver.c: relock driver lock if an error occurs in
qemuDomainObjBeginJobWithDriver, enter/exit monitor with driver
in qemudDomainSave
On kernels with HZ=100, the resolution of sleeps in poll() is
quite bad. Doing a precise check on the expiry time vs the
current time will thus often thing the timer has not expired
even though we're within 10ms of the expected expiry time. This
then causes another pointless sleep in poll() for <10ms. Timers
do not need to have such precise expiration, so we treat a timer
as expired if it is within 20ms of the expected expiry time. This
also fixes the eventtest.c test suite on kernels with HZ=100
* daemon/event.c: Add 20ms fuzz when checking for timer expiry
The instruction "See Makefile.am" in libvirt.private_syms
always makes me think that this file is autogenerated
and should not be touched manually. This patch spares
every reader of libvirt.private_syms the hassle of
reading Makefile.am before augmenting libvirt.private_syms.

Introduce a new type="dir" mode for <disks> that allows use of
QEMU's virtual FAT block device driver. eg
<disk type='dir' device='floppy'>
