Done mechanically with:
$ git grep -l '\bDEBUG0\? *(' | xargs -L1 sed -i 's/\bDEBUG0\? *(/VIR_&/'
followed by manual deletion of qemudDebug in daemon/libvirtd.c, along
with a single 'make syntax-check' fallout in the same file, and the
actual deletion in src/util/logging.h.
* src/util/logging.h (DEBUG, DEBUG0): Delete.
* daemon/libvirtd.h (qemudDebug): Likewise.
* global: Change remaining clients over to VIR_DEBUG counterpart.
Partial reversion of commit 76d87a59, now that bootstrap is smarter.
* .gnulib: Update to latest, for poll and bootstrap fixes.
* bootstrap: Resync from gnulib.
* autogen.sh: Drop redundant tool checks; bootstrap does them
better, by honoring environment variables.
* examples/domain-events/events-c/Makefile.am (INCLUDES)
(event_test_LDADD): Use gnulib library during build.
* bootstrap.conf (gnulib_tool_option_extras): Revert --libtool
addition, now that updated bootstrap does it for us.

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

IO error events
* include/libvirt/libvirt.h.in: Define new IO error event ID

This introduces a new event type
VIR_DOMAIN_EVENT_ID_WATCHDOG
This event includes the action that is about to be taken
as a result of the watchdog triggering
typedef enum {
VIR_DOMAIN_EVENT_WATCHDOG_NONE = 0,
VIR_DOMAIN_EVENT_WATCHDOG_PAUSE,
VIR_DOMAIN_EVENT_WATCHDOG_RESET,
VIR_DOMAIN_EVENT_WATCHDOG_POWEROFF,
VIR_DOMAIN_EVENT_WATCHDOG_SHUTDOWN,
VIR_DOMAIN_EVENT_WATCHDOG_DEBUG,
} virDomainEventWatchdogAction;
Thus there is a new callback definition for this event type
typedef void (*virConnectDomainEventWatchdogCallback)(virConnectPtr conn,
virDomainPtr dom,
int action,
void *opaque);
* daemon/remote.c: Dispatch watchdog events to client
* examples/domain-events/events-c/event-test.c: Watch for

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.
* daemon/remote.c: Dispatch RTC change events to client
* examples/domain-events/events-c/event-test.c: Watch for
RTC change events
* include/libvirt/libvirt.h.in: Define new RTC change event ID
and callback signature

* src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h,
src/qemu/qemu_monitor_json.c: Watch for RTC_CHANGE event
from QEMU monitor
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
reboot events
* include/libvirt/libvirt.h.in: Define new reboot event ID
