Can you clarify your setup ? Are you using FireCracker + VMWare as hypervisors ?

Does this happen only with FireCracker VMs ? Make sure you have FireEdge [properly configured](https://docs.opennebula.io/6.6/installation_and_configuration/opennebula_services/fireedge.html?highlight=fireedge#configure-sunstone-for-vmrc-and-guacamole)
