Fixed In Version:	3.6.5-1	Doc Type:	Bug Fix
Doc Text:	Previously when the ovirt guest agent service has been restarted (e.g. the VM restarted or just the service) the negotiated protocol version between hypervisor and guest os dropped to 0 which caused that all newer features which would have been supported by the guest agent wouldn't be available. This bug fix resolves this issue.	Story Points:	---
