virDomainManagedSave() is to be run on a running domain. Once the call
complete, as in virDomainSave() the domain is stopped upon completion,
but there is no restore counterpart as any order to start the domain
from the API would load the state from the managed file, similary if
the domain is autostarted when libvirtd starts.
Once a domain has restarted his managed save image is destroyed,
basically managed save image can only exist for a stopped domain,
for a running domain that would be by definition outdated data.

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
and emits a generic VIR_DOMAIN_EVENT_SUSPENDED_PAUSED event
* include/libvirt/libvirt.h.in: Add VIR_DOMAIN_EVENT_SUSPENDED_IOERROR
* src/qemu/qemu_driver.c: Update VM state to paused when IO error
or watchdog events occurrs
* src/qemu/qemu_monitor_json.c: Fix typo in disk IO event name
This flag is used in migration prepare step to send updated XML
definition of a guest.
Also ``virsh dumpxml --update-cpu [--inactive] guest'' command can be
used to see the updated CPU requirements.
This patch adds the implementation of the public API for the network

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.

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.

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);
This is currently wired up to the QEMU block IO error events

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.

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.
* daemon/remote.c: Dispatch reboot events to client
* examples/domain-events/events-c/event-test.c: Watch for

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

The new virDomainAbortJob() method provides a way for a second
thread to abort an ongoing job run by another thread. This
extends to any API with which the virDomainGetJobInfo() API
is intended to work. Cancellation is not guarenteed, rather best
effort on part of the hypervisor and not required to be implmented.
* include/libvirt/libvirt.h.in: Define virDomainAbortJob()

info on currently running jobs on a virDomainpPtr. APIs that

virDomainMigrate
virDomainMigrateToURI
virDomainSave
virDomainRestore
virDomainCoreDump
These all take a potentially long time and benefit from monitoring.

instead of restarting it if --crash is passed.
* src/xen/xend_internal.c (xenDaemonDomainCoreDump): Support --crash.
* tools/virsh.c (opts_dump): Add --crash.
(cmdDump): Map it to flags for virDomainCoreDump and pass them.

There is currently no way to determine the libvirt version of a remote

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.

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.

* src/conf/domain_conf.c: Throw an error if guestfwd address isn't IPv4
and cleanup a number of parsing return error values.
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.

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.

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.

* src/storage_encryption_conf.c, src/storage_encryption_conf.h:
Storage UUID in raw format, and require it to be present in
XML. Use UUID parser to validate.
* secret_conf.h, secret_conf.c: Generate a UUID if none is provided.
Storage UUID in raw format.
* src/secret_driver.c: Adjust to deal with raw UUIDs. Save secrets
in a filed with printable UUID, instead of base64 UUID.
* src/virsh.c: Adjust for changed public API contract of
virSecretGetUUIDString.
* src/storage_Backend.c: DOn't undefine secret we just generated
upon successful volume creation. Fix to handle raw UUIDs. Generate
a non-clashing UUID
* src/qemu_driver.c: Change to use lookupByUUID instead of
lookupByUUIDString
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.)
* include/libvirt/virterror.h, src/virterror.c (VIR_ERR_NO_SECRET): New
error number.
* po/POTFILES.in, src/Makefile.am: Add secret_driver.
* bootstrap: Use gnulib's base64 module.
* src/secret_driver.c, src.secret_driver.h, src/libvirt_private.syms:
Add local secret driver.
* qemud/qemud.c (qemudInitialize): Use the local secret driver.
* include/libvirt/virterror.h, src/virterror.c: Add VIR_WAR_NO_SECRET
* src/libvirt_private.syms, src/datatypes.h, src/datatypes.c: Type
virSecret struct definition and helper APIs
* src/driver.h: Sub-driver API definitions for secrets
* src/libvirt.c: Define new sub-driver for secrets
This patch adds a "secret" as a separately managed object, using a
special-purpose API to transfer the secret values between nodes and
libvirt users.
* docs/schemas/secret.rng, docs/schemas/Makefilem.am: Add new
schema for virSecret objects
* docs/*html: Re-generated
* docs/formatsecret.html.in, docs/sitemap.html.in: Add page
describing the virSecret XML schema
* include/libvirt/libvirt.h.in: Define the new virSecret public
API
* src/libvirt_public.syms: Export symbols for new public APIs
* mingw32-libvirt.spec.in, libvirt.spec.in: Add secret.rng to
files list
