An update. I compiled and ran the example provided with the src code event-test.c and this gave the same error. Interestingly, if I run the event-test.py script (i ran once with use_pure_python_event_loop set to true and once with false), it runs fine, both with pure and native event loop implementations. What could be the problem?

I am trying to register for VM events using virConnectDomainEventRegisterAny, but that is returning with the error "libvir: Remote error : this function is not supported by the connection driver: no event support" I have registered for the default event implementation (as suggested in the response to an earlier post related to this problem) prior to calling *RegisterAny, but that is not helping. Browsing through the coe, it seems to me this has to do with the timer support in the domainEventState, just a guess. if (priv->domainEventState->timer < 0) { remoteError(VIR_ERR_NO_SUPPORT, "%s", _("no event support")); goto done; } I am using Centos 6 with KVM QEMU.
