Well we had lifecycle event anyway because of stop handler so I decided to keep sending it. However I'm not sure why it was not sent in qemuDomainSuspend originally. For example for migration we do send event. Looks like this event does not hurt anyone if it survives up to now. I'm ok with commit message to if the case.
