e03a62b456 snapshot: add flag for requesting disk snapshot
Prior to this patch, <domainsnapshot>/<disks> was ignored.  This

be useful to have a <disks> specification alongside a system
checkpoint).

6f66423e17 snapshot: allow halting after snapshot
Since a snapshot is fully recoverable, it is useful to have a
snapshot as a means of hibernating a guest, then reverting to
the snapshot to wake the guest up.  This mode of usage is
similar to 'virsh save/virsh restore', except that virsh
save uses an external file while virsh snapshot keeps the
vm state internal to a qcow2 file.  However, it only works on
persistent domains.

In the usage pattern of snapshot/revert for hibernating a guest,
there is no need to keep the guest running between the two points
in time, especially since that would generate runtime state that
would just be discarded.  Add a flag to make it possible to
stop the domain after the snapshot has completed.

New flag.
* src/libvirt.c (virDomainSnapshotCreateXML): Document it.

3d77d0a644 snapshot: introduce new deletion flag
Reverting to a state prior to an external snapshot risks
corrupting any other branches in the snapshot hierarchy that
were using the snapshot as a read-only backing file.  So
disk snapshot code will default to preventing reverting to
a snapshot that has any children, meaning that deleting just
the children of a snapshot becomes a useful operation in
preparing that snapshot for being a future reversion target.
The code for the new flag is simple - it's one less deletion,
plus a tweak to keep the current snapshot correct.

(VIR_DOMAIN_SNAPSHOT_DELETE_CHILDREN_ONLY): New flag.
* src/libvirt.c (virDomainSnapshotDelete): Document it, and

282fe1f08c snapshot: prevent stranding snapshot data on domain destruction
Just as leaving managed save metadata behind can cause problems
when creating a new domain that happens to collide with the name
of the just-deleted domain, the same is true of leaving any
snapshot metadata behind.  For safety sake, extend the semantic
change of commit b26a9fa9 to also cover snapshot metadata as a
reason to reject undefining an inactive domain.  A future patch
will make sure that shutdown of a transient domain automatically
deletes snapshot metadata (whether by destroy, shutdown, or
guest-initiated action).  Management apps of transient domains
should take care to capture xml of snapshots, if it is necessary
to recreate the snapshot metadata on a later transient domain
with the same name and uuid.

This also documents a new flag that hypervisors can choose to
support as a shortcut for taking care of the metadata as part of
the undefine process; however, nontrivial driver support for these
flags will be deferred to future patches.

Note that ESX and VBox can never be transient; therefore, they
do not have to worry about automatic cleanup after shutdown
(the persistent domain still remains); likewise they never
store snapshot metadata, so the undefine flag is trivial.
The nontrivial work remaining is thus in the qemu driver.

the limitations.

af65695af0 snapshot: allow recreation of metadata
The first two flags are essential for being able to replicate
snapshot hierarchies across multiple hosts, which will come in
handy for supervised migrations.  It also allows a management app
to take a snapshot of a transient domain, save the metadata, stop
the domain, recreate a new transient domain by the same name,
redefine the snapshot, then revert to it.

This is not quite as convenient as leaving the metadata behind
after a domain is no longer around, but doing that has a few
problems: 1. the libvirt API can only delete snapshot metadata
if there is a valid domain handle to use to get to that snapshot
object - if stale data is left behind without a domain, there is
no way to request that the data be cleaned up. 2. creating a new
domain with the same name but different uuid than the older
domain where a snapshot existed cannot use the older snapshot
data; this risks confusing libvirt, and forbidding the stale
data is similar to the recent patch to forbid stale managed save.

The first two flags might be useful on hypervisors with no metadata,
but only for modifying the notion of the current snapshot;
however, I don't know how to do that for ESX or VBox.

The third flag is a convenience option, to combine a creation with
a delete metadata into one step.  It is trivial for hypervisors
with no metadata.

The qemu changes will be involved enough to warrant a separate patch.

9f5e53e211 snapshot: identify which snapshots have metadata
To make it easier to know when undefine will fail because of existing

795fe9b2fa snapshot: allow deletion of just snapshot metadata
A future patch will make it impossible to remove a domain if it
would leave behind any libvirt-tracked metadata about snapshots,
since stale metadata interferes with a new domain by the same name.
But requiring snaphot contents to be deleted before removing a
domain is harsh; with qemu, qemu-img can still make use of the
contents after the libvirt domain is gone.  Therefore, we need
an option to get rid of libvirt tracking information, but not
the actual contents.  For hypervisors that do not track any
metadata in libvirt, the implementation is trivial; all remaining
hypervisors (really, just qemu) will be dealt with separately.

3cff66f487 snapshot: fine-tune ability to start paused
While it is nice that snapshots and saved images remember whether
the domain was running or paused, sometimes the restoration phase
wants to guarantee a particular state (paused to allow hot-plugging,
or running without needing to call resume).  This introduces new
flags to allow the control, and a later patch will implement the
flags for qemu.

c1ff5dc63d snapshot: better events when starting paused
There are two classes of management apps that track events - one
that only cares about on/off (and only needs to track EVENT_STARTED
and EVENT_STOPPED), and one that cares about paused/running (also
tracks EVENT_SUSPENDED/EVENT_RESUMED).  To keep both classes happy,
any transition that can go from inactive to paused must emit two
back-to-back events - one for started and one for suspended (since
later resuming of the domain will only send RESUMED, but the first
class isn't tracking that).

This also fixes a bug where virDomainCreateWithFlags with the
VIR_DOMAIN_START_PAUSED flag failed to start paused when restoring
from a managed save image.

27758859c7 storage: Add fs pool formatting
This patch adds the ability to make the filesystem for a filesystem
pool during a pool build.

The patch adds two new flags, no overwrite and overwrite, to control
when mkfs gets executed.  By default, the patch preserves the
current behavior, i.e., if no flags are specified, pool build on a
filesystem pool only makes the directory on which the filesystem
will be mounted.

If the no overwrite flag is specified, the target device is checked
to determine if a filesystem of the type specified in the pool is
present.  If a filesystem of that type is already present, mkfs is
not executed and the build call returns an error.  Otherwise, mkfs
is executed and any data present on the device is overwritten.

If the overwrite flag is specified, mkfs is always executed, and any
existing data on the target device is overwritten unconditionally.

ce93f64b1e Fix keymap used to talk with QEMU
The QEMU 'sendkey' command expects keys to be encoded in the same
way as the RFB extended keycode set. Specifically it wants extended

driver

d58e91a812 qemu: Migration job on source daemon
Make MIGRATION_OUT use the new helper methods.

This also introduces new protection to migration v3 process: the
migration job is held from Begin to Confirm to avoid changes to a domain
during migration (esp. between Begin and Perform phases). This change is
automatically applied to p2p and tunneled migrations. For normal
migration, this requires support from a client. In other words, if an
old (pre 0.9.4) client starts normal migration of a domain, the domain
will not be protected against changes between Begin and Perform steps.

d2a929d4b3 save: new API to manipulate save file images
Modifying the xml on either save or restore only gets you so
far - you have to remember to 'virsh dumpxml dom' just prior

1700345708 error: add new error type for reflecting partial API support
VIR_ERR_INVALID_ARG implies that an argument cannot possibly
be correct, given the current state of the API.
VIR_ERR_CONFIG_UNSUPPORTED implies that a configuration is
wrong, but arguments aren't configuration.
VIR_ERR_NO_SUPPORT implies that a function is completely
unimplemented.

But in the case of a function that is partially implemented,
yet the full power of the API is not available for that
driver, none of the above messages make sense.  Hence a new
error message, implying that the argument is known to comply
with the current state of the API, and that while the driver
supports aspects of the function, it does not support that
particular use of the argument.

A good use case for this is a driver that supports
virDomainSaveFlags, but not the dxml argument of that API.

It might be feasible to also use this new error for all functions
that check flags, and which accept fewer flags than what is possible
in the public API.  But doing so would get complicated, since
neither libvirt.c nor the remote driver may do flag filtering,
and every other driver would have to do a two-part check, first
using virCheckFlags on all public flags (which gives
VIR_ERR_INVALID_ARG for an impossible flag), followed by a
particular mask check for VIR_ERR_ARGUMENT_UNSUPPORTED (for a
possible public flag but unsupported by this driver).

* include/libvirt/virterror.h (VIR_ERR_ARGUMENT_UNSUPPORTED): New
error.

b26a9fa9c2 undefine: Define the new API
This introduces a new API virDomainUndefineFlags to control the
domain undefine process, as the existing API virDomainUndefine
doesn't support flags.

Currently only flag VIR_DOMAIN_UNDEFINE_MANAGED_SAVE is supported.
If the domain has a managed save image, including
VIR_DOMAIN_UNDEFINE_MANAGED_SAVE in @flags will also remove that
file, and omitting the flag will cause undefine process to fail.

This patch also changes the behavior of virDomainUndefine, if the
domain has a managed save image, the undefine will be refused.

18d561c7a4 public API: prefer unsigned int for flags
Most APIs use 'unsigned int flags'; but a few stragglers were using
a signed value.  In particular, the vir*GetXMLDesc APIs were
split-brain, with inconsistent choice of types.  Although it is
an API break to use 'int' instead of 'unsigned int', it is ABI
compatible (pre-compiled apps will have no difference in behavior),
and generally apps can be recompiled without any issue (only rare
apps that compiled with extremely high warning levels, or which
pass libvirt API around as typed function pointers, would have to
make any code changes to deal with the change).

The migrate APIs use 'unsigned long flags', which can't be changed,
due to ABI constraints.

This patch intentionally touches only the public API, to prove the
claim that most existing code (including driver callbacks and virsh)
still compiles just fine in spite of the type change.

e261987c5a vcpupin: introduce the new libvirt API (virDomainGetVcpupinInfo)
This patch introduces a new libvirt API (virDomainGetVcpupinInfo),
as a counterpart to virDomainPinVcpuFlags.

We can use virDomainGetVcpus API to retrieve CPU affinity information,
but can't use this API against inactive domains (at least in case of KVM),
as it lacks a flags parameter.
The usual thing is to add a new virDomainGetVcpusFlags, but that API name
is already occupied by the counterpart to virDomainGetMaxVcpus, which
has a completely different signature.

The virDomainGetVcpupinInfo is the new API to retrieve CPU affinity
information of active and inactive domains.  While the usual convention
is to list an array before its length, this API violates that rule
in order to be more like virDomainGetVcpus (where maxinfo was doing
double-duty as the length of two different arrays).

3ba937da42 Allow automatic kill of guests when a connection is closed
If an application is using libvirt + KVM as a piece of its
internal infrastructure to perform a specific task, it can
be desirable to guarentee the VM dies when the virConnectPtr
disconnects from libvirtd. This ensures the app can't leak
any VMs it was using. Adding VIR_DOMAIN_START_AUTOKILL as
a flag when starting guests enables this to be done.

* src/qemu/qemu_driver.c: Support automatic killing of guests

    stat_put(dict, "actual", actual);
    stat_put(dict, "mem_swapped_in", dev->stats[VIRTIO_BALLOON_S_SWAP_IN]);
    stat_put(dict, "mem_swapped_out", dev->stats[VIRTIO_BALLOON_S_SWAP_OUT]);

    stat_put(dict, "total_mem", dev->stats[VIRTIO_BALLOON_S_MEMTOT]);

But it later disabled all the stats except "actual" by commit
07b0403dfc2b2ac179ae5b48105096cc2d03375a.

libvirt doesn't parse "actual", so user will always see a empty result
with "virsh dommemstat $domain". Even qemu haven't disabled the stats,
we should support parsing "actual".

a6135ec1e6 Introduce a new event emitted when a virtualization failure occurs
This introduces a new domain

  VIR_DOMAIN_EVENT_ID_CONTROL_ERROR

Which uses the existing generic callback

typedef void (*virConnectDomainEventGenericCallback)(virConnectPtr conn,
                                                     virDomainPtr dom,
                                                     void *opaque);

This event is intended to be emitted when there is a failure in
some part of the domain virtualization system. Whether the domain
continues to run/exist after the failure is an implementation
detail specific to the hypervisor.

The idea is that with some types of failure, hypervisors may
prefer to leave the domain running in a "degraded" mode of
operation. For example, if something goes wrong with the QEMU
monitor, it is possible to leave the guest OS running quite
happily. The mgmt app will simply loose the ability todo various
tasks. The mgmt app can then choose how/when to deal with the
failure that occured.

ba0b5934b3 interface: new public API for network config change transactions
This is the API agreed on in:

  https://www.redhat.com/archives/libvir-list/2011-May/msg00026.html

(with a slight name change to use "...begin" rather than
"...start"). This implements transactional changes to the host network
config. When a transaction is begun with ncf_change_begin(), all other
netcf APIs will continue to work as they always have, but a snapshot
of the existing config will be taken, allowing reversion (rollback,
using ncf_change_rollback()) to the exact state of config at the time
ncf_change_begin() was called. Alternately, if it's determined that
the new changes are acceptable, ncf_change_commit() can be called,
which will eliminate the snapshot and make the changes permanent.

As a failsafe measure, if neither ncf_change_commit() or
ncf_change_rollback() is called by the next time the system reboots,
the netcf-transaction initscript will be automatically called to
rollback the changes.

4591df766d Remove the Open Nebula driver
The Open Nebula driver has been unmaintained since it was first
introduced. The only commits have been for tree-wide cleanups.
It also has a major design flaw, in that it only knows about guests
that it has created itself, which makes it of very limited use.

Discussions wrt evolution of the VMWare ESX driver, concluded that
it should limit itself to single-node ESX operation and not try to
manage the multi-node architecture of VirtualCenter. Open Nebula
is a cluster like Virtual Center, not a single node system, so
the same reasoning applies.

The DeltaCloud project includes an Open Nebula driver and is a much
better fit architecturally, since it is explicitly targetting the
distributed multihost cluster scenario.

Thus this patch deletes the libvirt Open Nebula driver with the
recommendation that people use DeltaCloud for managing it instead.

2b84e445d5 Add libxenlight driver
Add a new xen driver based on libxenlight [1], which is the primary
toolstack starting with Xen 4.1.0.  The driver is stateful and runs
privileged only.

Like the existing xen-unified driver, the libxenlight driver is
accessed with xen:// URI.  Driver selection is based on the status
of xend.  If xend is running, the libxenlight driver will not load
and xen:// connections are handled by xen-unified.  If xend is not
running *and* the libxenlight driver is available, xen://
connections are deferred to the libxenlight driver.

V6:
 - Address several code style issues noted by Daniel Veillard
 - Make drive work with xen:/// URI
 - Hold domain object reference while domain is injected in
   libvirt event loop.  Race found and fixed by Markus Groß.

V5:
 - Ensure events are unregistered when domain private data
   is destroyed.  Discovered and fixed by Markus Groß.

V4:
 - Handle restart of libvirtd, reconnecting to previously
   started domains
 - Rebased to current master
 - Tested against Xen 4.1 RC7-pre (c/s 22961:c5d121fd35c0)

V3:
  - Reserve vnc port within driver when autoport=yes

V2:
  - Update to Xen 4.1 RC6-pre (c/s 22940:5a4710640f81)
  - Rebased to current master
  - Plug memory leaks found by Stefano Stabellini and valgrind
  - Handle SHUTDOWN_crash domain death event

2ed6cc7bec Expose event loop implementation as a public API
Not all applications have an existing event loop they need
to integrate with. Forcing them to implement the libvirt
event loop integration APIs is an undue burden. This just
exposes our simple poll() based implementation for apps
to use. So instead of calling

   virEventRegister(....callbacks...)

The app would call

   virEventRegisterDefaultImpl()

And then have a thread somewhere calling

    static bool quit = false;
    ....
    while (!quit)
      virEventRunDefaultImpl()

2169472ab6 qemu: Add shortcut for HMP pass through
Currently users who want to use virDomainQemuMonitorCommand() API or
it's virsh equivalent has to use the same protocol as libvirt uses for
communication to qemu. Since the protocol is QMP with current qemu and
HMP much more usable for humans, one ends up typing something like the
following:

    virsh qemu-monitor-command DOM \
'{"execute":"human-monitor-command","arguments":{"command-line":"info kvm"}}'

which is not a very convenient way of debugging qemu.

This patch introduces --hmp option to qemu-monitor-command, which says
that the provided command is in HMP. If libvirt uses QMP to talk with
qemu, the command will automatically be converted into QMP. So the
example above is simplified to just

    virsh qemu-monitor-command --hmp DOM "info kvm"

Also the result is converted from

    {"return":"kvm support: enabled\r\n"}

to just plain HMP:

    kvm support: enabled

If libvirt talks to qemu in HMP, --hmp flag is obviously a noop.

2deb32ae02 virterror: avoid API breakage with vmware
Fix glitch in commit cddd2a06 (thankfully post-0.8.6, so no
released version has the glitch).

Document and try to workaround glitch in commit 46e9b0f (in 0.8.0),
which invalidated 6 virErrorNumber values dating as far back as 0.7.1.

My audit did not find any other glitches until pre-0.1.0 days.  I'm
not sure how to add a syntax-check off the top of my head, but
hopefully the explicit numbering will make people think twice about
renumbering in the future.

* include/libvirt/virterror.h (virErrorDomain): Avoid inserting
new values in the middle, and add explicit numbering to help avoid
this in the future.
(virErrorNumber): Add explicit numbering, and document the snafu.
* src/remote/remote_driver.c (remoteIO): Compensate for the snafu.

ac9dd4a676 Fix host CPU counting on unusual NUMA topologies
The nodeinfo structure includes

    nodes   : the number of NUMA cell, 1 for uniform mem access
    sockets : number of CPU socket per node
    cores   : number of core per socket
    threads : number of threads per core

which does not work well for NUMA topologies where each node does not
consist of integral number of CPU sockets.

We also have VIR_NODEINFO_MAXCPUS macro in public libvirt.h which
computes maximum number of CPUs as (nodes * sockets * cores * threads).

As a result, we can't just change sockets to report total number of
sockets instead of sockets per node. This would probably be the easiest
since I doubt anyone is using the field directly. But because of the
macro, some apps might be using sockets indirectly.

This patch leaves sockets to be the number of CPU sockets per node (and
fixes qemu driver to comply with this) on machines where sockets can be
divided by nodes. If we can't divide sockets by nodes, we behave as if
there was just one NUMA node containing all sockets. Apps interested in
NUMA should consult capabilities XML, which is what they probably do
anyway.

This way, the only case in which apps that care about NUMA may break is
on machines with funky NUMA topology. And there is a chance libvirt
wasn't able to start any guests on those machines anyway (although it
depends on the topology, total number of CPUs and kernel version).
Nothing changes at all for apps that don't care about NUMA.

To avoid the need for duplicating implementations of virStream

FD based stream. This code is copied from the existing impl

they would block on I/O

 - Added versioning information to the libvirt-qemu.so

Changes since v2:

Support for live migration between hosts that do not share storage was
added to qemu-kvm release 0.12.1.
It supports two flags:
-b migration without shared storage with full disk copy
-i migration without shared storage with incremental copy (same base image
shared between source and destination).

I tested the live migration without shared storage (both flags) for native
and p2p with and without tunnelling.  I also verified that the fix doesn't
affect normal migration with shared storage.

This introduces a new event type

   VIR_DOMAIN_EVENT_ID_IO_ERROR_REASON

This event is the same as the previous VIR_DOMAIN_ID_IO_ERROR

Thus there is a new callback definition for this event type

cd2404a3c3 Keep track of guest paused state after disk IO / watchdog events
When a watchdog/IO error occurs, one of the possible actions that
QEMU might take is to pause the guest. In this scenario libvirt
needs to update its internal state for the VM, and emit a
lifecycle event:

  VIR_DOMAIN_EVENT_SUSPENDED

with a detail being one of:

  VIR_DOMAIN_EVENT_SUSPENDED_IOERROR
  VIR_DOMAIN_EVENT_SUSPENDED_WATCHDOG

To future proof against possible QEMU support for multiple monitor
consoles, this patch also hooks into the 'STOPPED' event in QEMU

46a2ea3689 Introduce a new virDomainUpdateDeviceFlags public API
The current virDomainAttachDevice API can be (ab)used to change
the media of an existing CDROM/Floppy device. Going forward there
will be more devices that can be configured on the fly and overloading
virDomainAttachDevice for this is not too pleasant. This patch adds
a new virDomainUpdateDeviceFlags() explicitly just for modifying
existing devices.

987e31edc9 Add domain events for graphics network clients
This introduces a new event type

   VIR_DOMAIN_EVENT_ID_GRAPHICS

The same event can be emitted in 3 scenarios

  typedef enum {
      VIR_DOMAIN_EVENT_GRAPHICS_CONNECT = 0,
      VIR_DOMAIN_EVENT_GRAPHICS_INITIALIZE,
      VIR_DOMAIN_EVENT_GRAPHICS_DISCONNECT,
  } virDomainEventGraphicsPhase;

Connect/disconnect are triggered at socket accept/close.
The initialize phase is immediately after the protocol
setup and authentication has completed. ie when the
client is authorized and about to start interacting with
the graphical desktop

This event comes with *a lot* of potential information

 - IP address, port & address family of client
 - IP address, port & address family of server
 - Authentication scheme (arbitrary string)
 - Authenticated subject identity. A subject may have
   multiple identities with some authentication schemes.
   For example, vencrypt+sasl results in a x509dname
   and saslUsername identities.

This results in a very complicated callback :-(

   typedef enum {
      VIR_DOMAIN_EVENT_GRAPHICS_ADDRESS_IPV4,
      VIR_DOMAIN_EVENT_GRAPHICS_ADDRESS_IPV6,
   } virDomainEventGraphicsAddressType;

   struct _virDomainEventGraphicsAddress {
       int family;
       const char *node;
       const char *service;
   };
   typedef struct _virDomainEventGraphicsAddress virDomainEventGraphicsAddress;
   typedef virDomainEventGraphicsAddress *virDomainEventGraphicsAddressPtr;

   struct _virDomainEventGraphicsSubject {
      int nidentity;
      struct {
          const char *type;
          const char *name;
      } *identities;
   };
   typedef struct _virDomainEventGraphicsSubject virDomainEventGraphicsSubject;
   typedef virDomainEventGraphicsSubject *virDomainEventGraphicsSubjectPtr;

   typedef void (*virConnectDomainEventGraphicsCallback)(virConnectPtr conn,
                                                         virDomainPtr dom,
                                                         int phase,
                                                         virDomainEventGraphicsAddressPtr local,
                                                         virDomainEventGraphicsAddressPtr remote,
                                                         const char *authScheme,
                                                         virDomainEventGraphicsSubjectPtr subject,
                                                         void *opaque);

The wire protocol is similarly complex

   struct remote_domain_event_graphics_address {
     int family;
     remote_nonnull_string node;
     remote_nonnull_string service;
   };

   const REMOTE_DOMAIN_EVENT_GRAPHICS_IDENTITY_MAX = 20;

   struct remote_domain_event_graphics_identity {
     remote_nonnull_string type;
     remote_nonnull_string name;
   };

   struct remote_domain_event_graphics_msg {
     remote_nonnull_domain dom;
     int phase;
     remote_domain_event_graphics_address local;
     remote_domain_event_graphics_address remote;
     remote_nonnull_string authScheme;
     remote_domain_event_graphics_identity subject<REMOTE_DOMAIN_EVENT_GRAPHICS_IDENTITY_MAX>;
   };

This is currently implemented in QEMU for the VNC graphics
protocol, but designed to be usable with SPICE graphics in
the future too.

71d793faaf Add support for an explicit IO error event
This introduces a new event type

   VIR_DOMAIN_EVENT_ID_IO_ERROR

This event includes the action that is about to be taken
as a result of the watchdog triggering

  typedef enum {
     VIR_DOMAIN_EVENT_IO_ERROR_NONE = 0,
     VIR_DOMAIN_EVENT_IO_ERROR_PAUSE,
     VIR_DOMAIN_EVENT_IO_ERROR_REPORT,
  } virDomainEventIOErrorAction;

In addition it has the source path of the disk that had the
error and its unique device alias. It does not include the
target device name (/dev/sda), since this would preclude
triggering IO errors from other file backed devices (eg
serial ports connected to a file)

Thus there is a new callback definition for this event type

typedef void (*virConnectDomainEventIOErrorCallback)(virConnectPtr conn,
                                                     virDomainPtr dom,
                                                     const char *srcPath,
                                                     const char *devAlias,
                                                     int action,
                                                     void *opaque);

32e6ac9c26 Add support for an explicit RTC change event
This introduces a new event type

   VIR_DOMAIN_EVENT_ID_RTC_CHANGE

This event includes the new UTC offset measured in seconds.
Thus there is a new callback definition for this event type

 typedef void (*virConnectDomainEventRTCChangeCallback)(virConnectPtr conn,
                                                        virDomainPtr dom,
                                                        long long utcoffset,
                                                        void *opaque);

If the guest XML configuration for the <clock> is set to
offset='variable', then the XML will automatically be
updated with the new UTC offset value. This ensures that
during migration/save/restore the new offset is preserved.

8613273458 Add support for an explicit guest reboot event
The reboot event is not a normal lifecycle event, since the
virtual machine on the host does not change state. Rather the
guest OS is resetting the virtual CPUs. ie, the QEMU process
does not restart. Thus, this does not belong in the current
lifecycle events callback.

This introduces a new event type

    VIR_DOMAIN_EVENT_ID_REBOOT

It takes no parameters, besides the virDomainPtr, so it can
use the generic callback signature.

4445723811 Introduce a new public API for domain events
The current API for domain events has a number of problems

 - Only allows for domain lifecycle change events
 - Does not allow the same callback to be registered multiple times
 - Does not allow filtering of events to a specific domain

This introduces a new more general purpose domain events API

  typedef enum {
     VIR_DOMAIN_EVENT_ID_LIFECYCLE = 0,       /* virConnectDomainEventCallback */
      ...more events later..
  }

  int virConnectDomainEventRegisterAny(virConnectPtr conn,
                                       virDomainPtr dom, /* Optional, to filter */
                                       int eventID,
                                       virConnectDomainEventGenericCallback cb,
                                       void *opaque,
                                       virFreeCallback freecb);

  int virConnectDomainEventDeregisterAny(virConnectPtr conn,
                                         int callbackID);

Since different event types can received different data in the callback,
the API is defined with a generic callback. Specific events will each
have a custom signature for their callback. Thus when registering an
event it is neccessary to cast the callback to the generic signature

eg

  int myDomainEventCallback(virConnectPtr conn,
                            virDomainPtr dom,
                            int event,
                            int detail,
                            void *opaque)
  {
    ...
  }

  virConnectDomainEventRegisterAny(conn, NULL,
                                   VIR_DOMAIN_EVENT_ID_LIFECYCLE,
                                   VIR_DOMAIN_EVENT_CALLBACK(myDomainEventCallback)
                                   NULL, NULL);

The VIR_DOMAIN_EVENT_CALLBACK() macro simply does a "bad" cast
to the generic signature

  domain events

c04498b305 New APIs for checking some object properties
Introduce a number of new APIs to  expose some boolean properties
of objects, which cannot otherwise reliably determined, nor are
aspects of the XML configuration.

 * virDomainIsActive: Checking virDomainGetID is not reliable
   since it is not possible to distinguish between error condition
   and inactive domain for ID of -1.
 * virDomainIsPersistent: Check whether a persistent config exists
   for the domain

 * virNetworkIsActive: Check whether the network is active
 * virNetworkIsPersistent: Check whether a persistent config exists
   for the network

 * virStoragePoolIsActive: Check whether the storage pool is active
 * virStoragePoolIsPersistent: Check whether a persistent config exists
   for the storage pool

 * virInterfaceIsActive: Check whether the host interface is active

 * virConnectIsSecure: whether the communication channel to the
   hypervisor is secure
 * virConnectIsEncrypted: whether any network based commnunication
   channels are encrypted

NB, a channel can be secure, even if not encrypted, eg if it does
not involve the network, like a UNIX socket, or pipe.

 * src/driver.h: Define internal driver API
 * src/libvirt.c: Implement public API entry point
 * src/libvirt_public.syms: Export API symbols

9b6efcfef1 Allow timeouts waiting for QEMU job lock
Some monitor commands may take a very long time to complete. It is
not desirable to block other incoming API calls forever. With this
change, if an existing API call is holding the job lock, additional
API calls will not wait forever. They will time out after a short
period of time, allowing application to retry later.

* include/libvirt/virterror.h, src/util/virterror.c: Add new
  VIR_ERR_OPERATION_TIMEOUT error code
* src/qemu/qemu_driver.c: Change to a timed condition variable
  wait for acquiring the monitor job lock

753c6c9c75 Support reporting live interface IP/netmask
This patch adds the flag VIR_INTERFACE_XML_INACTIVE to
virInterfaceGetXMLDesc's flags. When it is*not* set (the default), the
live interface info will be returned in the XML (in particular, the IP
address(es) and netmask(s) will be retrieved by querying the interface
directly, rather than  reporting what's in the config file). The
backend of this is in netcf's ncf_if_xml_state() function.

* configure.in libvirt.spec.in: requires netcf >= 0.1.3
* include/libvirt/libvirt.h.in: adds flag VIR_INTERFACE_XML_INACTIVE
* src/conf/interface_conf.c src/interface/netcf_driver.c src/libvirt.c:
  update the parsing and backend routines accordingly
* tools/virsh.c: change interface edit to inactive definition and
  adds the inactive flag for interface dump

2d8d9b100b Finer grained migration control
Normally, when you migrate a domain from host A to host B,
the domain on host A remains defined but shutoff and the domain
on host B remains running but is a "transient".  Add a new
flag to virDomainMigrate() to allow the original domain to be
undefined on source host A, and a new flag to virDomainMigrate() to
allow the new domain to be persisted on the destination host B.

fae0da5c13 Support a new peer-to-peer migration mode & public API
Introduces several new public API options for migration

 - VIR_MIGRATE_PEER2PEER: With this flag the client only
   invokes the virDomainMigratePerform method, expecting
   the source host driver to do whatever is required to
   complete the entire migration process.
 - VIR_MIGRATE_TUNNELLED: With this flag the actual data
   for migration will be tunnelled over the libvirtd RPC
   channel. This requires that VIR_MIGRATE_PEER2PEER is
   also set.
 - virDomainMigrateToURI: This is variant of the existing
   virDomainMigrate method which does not require any
   virConnectPtr for the destination host. Given suitable
   driver support, this allows for all the same modes as
   virDomainMigrate()

The URI for VIR_MIGRATE_PEER2PEER must be a valid libvirt
URI. For non-p2p migration a hypervisor specific migration
URI is used.

virDomainMigrateToURI without a PEER2PEER flag is only
support for Xen currently, and it involves XenD talking
directly to XenD, no libvirtd involved at all.

* include/libvirt/libvirt.h.in: Add VIR_MIGRATE_PEER2PEER
  flag for migration
* src/libvirt_internal.h: Add feature flags for peer to
  peer migration (VIR_FEATURE_MIGRATE_P2P) and direct
  migration (VIR_MIGRATE_PEER2PEER mode)
* src/libvirt.c: Implement support for VIR_MIGRATE_PEER2PEER
  and virDomainMigrateToURI APIs.
* src/xen/xen_driver.c: Advertise support for DIRECT migration
* src/xen/xend_internal.c: Add TODO item for p2p migration
* src/libvirt_public.syms: Export virDomainMigrateToURI
  method
* src/qemu/qemu_driver.c: Add support for PEER2PEER and
  migration, and adapt TUNNELLED migration.
* tools/virsh.c: Add --p2p and --direct args and use the
  new virDomainMigrateToURI method where possible.

03d338608d Local file implementation of secret driver API
This implementation stores the secrets in an unencrypted text file,
for simplicity in implementation and debugging.

(Symmetric encryption, e.g. using gpgme, will not be difficult to add.
Because the TLS private key used by libvirtd is stored unencrypted,
encrypting the secrets file does not currently provide much additional
security.)

  error number.
