[libvirt] PATCH: Add domain event "detail" information
Daniel P. Berrange

As per our earlier discussion today, this patch expands the callback for
domain events so that it also gets a event type specific 'detail' field.
This is also kept as an int, and we define enumerations for the possible
values associated with each type. If a event type has no detail, 0 is
passed.
The RESTORED and SAVED event types disappear in this patch and just become
another piece of 'detail' to the STOPPED and STARTED events. I have also
renamed ADDED & REMOVED to DEFINED and UNDEFINED to match terminology we
have elsewhere & because the names were confusing me
Easiest to just look at the final set:
typedef enum {
VIR_DOMAIN_EVENT_DEFINED = 0,
VIR_DOMAIN_EVENT_UNDEFINED = 1,
VIR_DOMAIN_EVENT_STARTED = 2,
VIR_DOMAIN_EVENT_SUSPENDED = 3,
VIR_DOMAIN_EVENT_RESUMED = 4,
VIR_DOMAIN_EVENT_STOPPED = 5,
} virDomainEventType;
typedef enum {
VIR_DOMAIN_EVENT_STARTED_BOOTED = 0, /* Normal startup from boot */
VIR_DOMAIN_EVENT_STARTED_MIGRATED = 1, /* Incoming migration from another host */
VIR_DOMAIN_EVENT_STARTED_RESTORED = 2, /* Restored from a state file */
} virDomainEventStartedDetailType;
typedef enum {
VIR_DOMAIN_EVENT_STOPPED_SHUTDOWN = 0, /* Normal shutdown */
VIR_DOMAIN_EVENT_STOPPED_DESTROYED = 1, /* Forced poweroff from host */
VIR_DOMAIN_EVENT_STOPPED_CRASHED = 2, /* Guest crashed */
VIR_DOMAIN_EVENT_STOPPED_MIGRATED = 3, /* Migrated off to another host */
VIR_DOMAIN_EVENT_STOPPED_SAVED = 4, /* Saved to a state file */
VIR_DOMAIN_EVENT_STOPPED_FAILED = 5, /* Host emulator/mgmt failed */
} virDomainEventStoppedDetailType;
typedef enum {
VIR_DOMAIN_EVENT_DEFINED_ADDED = 0, /* Newly created config file */
VIR_DOMAIN_EVENT_DEFINED_UPDATED = 1, /* Changed config file */
} virDomainEventDefinedDetailType;
I don't make use of 'CRASHED' in QEMU driver yet. It might be useful in
Xen though - when a PV guest crashes, Xen stops the domain running, but
leaves it there in a shutoff state, but marked as crashed.
Now using the C event-test program you can see the effects:
myDomainEventCallback1 EVENT: Domain F9x86_64(2) Started Booted
myDomainEventCallback2 EVENT: Domain F9x86_64(2) Started Booted
myDomainEventCallback1 EVENT: Domain F9x86_64(-1) Stopped Destroyed
myDomainEventCallback2 EVENT: Domain F9x86_64(-1) Stopped Destroyed
myDomainEventCallback1 EVENT: Domain F9x86_64(3) Started Booted
myDomainEventCallback2 EVENT: Domain F9x86_64(3) Started Booted
myDomainEventCallback1 EVENT: Domain F9x86_64(3) Suspended
myDomainEventCallback2 EVENT: Domain F9x86_64(3) Suspended
myDomainEventCallback1 EVENT: Domain F9x86_64(3) Resumed
myDomainEventCallback2 EVENT: Domain F9x86_64(3) Resumed
myDomainEventCallback1 EVENT: Domain F9x86_64(-1) Stopped Shutdown
myDomainEventCallback2 EVENT: Domain F9x86_64(-1) Stopped Shutdown
Of the following sequence of actions
virsh start F9x86_64
virsh destroy F9x86_64
virsh start F9x86_64
virsh suspend F9x86_64
virsh resume F9x86_64
virsh shutdown F9x86_64
For the last 'shutdown' operation, you'll see the same if you just run
a graceful shutdown inside the guest itself.
NB, I've not tested saved/restored because my install of KVM is not new
enough to support that correctly, but I expect it to work without trouble.
Likewise for migration.
A word about migration...
- The destination host first gets a STARTED event, with detail MIGRATED
when it starts running
- The source host then gets a STOPPED event with detail MIGRATED when
it completes
- The destination host then gets a RESUMED event, on success, and
a STOPPED event with detail FAILED if migration aborts.
