The following testcase worked for me with a preseeded install, giving me
the following results:
myDomainEventLifecycleCallback EVENT: Domain desktop(12) Shutdown
Finished
myDomainEventLifecycleCallback EVENT: Domain desktop(12) Stopped
Shutdown
myDomainEventLifecycleCallback EVENT: Domain desktop(13) Started Booted
Test script is as follows, borrowing some boilerplate from libvirt-
python/examples/event-test.py:
#!/usr/bin/env python
import sys
import getopt
import os
import libvirt
import select
import errno
import time
import threading
eventLoopThread = None
def virEventLoopNativeRun():
while True:
libvirt.virEventRunDefaultImpl()
def virEventLoopNativeStart():
global eventLoopThread
libvirt.virEventRegisterDefaultImpl()
eventLoopThread = threading.Thread(target=virEventLoopNativeRun,
name="libvirtEventLoop")
eventLoopThread.setDaemon(True)
eventLoopThread.start()
def domEventToString(event):
domEventStrings = ( "Defined",
"Undefined",
"Started",
"Suspended",
"Resumed",
"Stopped",
"Shutdown",
"PMSuspended",
"Crashed",
)
return domEventStrings[event]
def myDomainEventLifecycleCallback (conn, dom, event, detail, opaque):
print("myDomainEventLifecycleCallback EVENT: Domain %s(%s) %s %s\n" %
(dom.name(), dom.ID(),
domEventToString(event),
domDetailToString(event, detail)))

domEventStrings = (
