Juniper NFX250 - Managing the VNF Life Cycle; Table 19: VNF Glossary

All VMs run in isolation and a state change in one VM does not affect another VM. When
the system restarts, the service VMs are brought online as specified in the persistent
configuration file. When you gracefully shut down the system, all VMs including the Junos
VMs are shut down.
Table 19 on page 106 provides a glossary of commonly used VNF acronyms and terms.

Managing the VNF Life Cycle
You can use the JDM CLI to manage the VNF. Additionally, libvirt software offers extensive
virtualization features. To ensure that you are not limited by the CLI, JDM provides an
option to operate VNF using an XML descriptor file. Network Configuration Protocol
(NETCONF) supports all VNF operations. Multiple VNFs can co-exist in a system and
you can configure multiple VNFs using either an XML descriptor file or an image.
NOTE: Ensure that VNF resources that are specified in the XML descriptor
file do not exceed the available system resources.
This topic covers the life-cycle management of a VNF.
