Since VNUML 1.9 an extension plugins mechanism has been developed, so new functionality can be added to create files and execute commands in the virtual machines. You can use the plugins included in the VNUML or develop your owns, using the VNUML plugins API.
Plugins included in the VNUML package:
- Ospfd, to configure OSPF daemons in the virtual machines
- Dhcp, to provide DHCP capabilities in the virtual machines
