Hi, I could find only one post related to this, but that did not address my 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. Thanks, Suresh
