[libvirt] PATCH: Add domain event "detail" information

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
