Are the VMs (or any other processes) on that host impacted? Does zabbix log any error messages? Can you spawn two instances on that box and let them e. g. transfer traffic via ttcp between each other and monitor that? From where do you login? Is this a LAN connection or could it be path MTU discovery issues over a WAN connection? I think, first priority should be to find out whether that's an "inner machine" or an "external network" issue.
