### end of control file ####

When all the files/folders are ready, execute the command to rebuild the .deb

# dpkg-deb -b python-vmcloud

Installation of VMcloud

# dpkg -i python-vmcloud.deb

because there are some dependencies, run the command to auto install them

# sudo apt-get -f install

Redo the dpkg installation again

# dpkg -i python-vmcloud

Set the SUID for the file /usr/bin/vmcnet
# sudo chmod 4775 /usr/bin/vmcnet

*** This allow the application to run as root.

Change the ownership to "root"
# chown root:root /usr/bin/vmcloud
# chown root:root /usr/bin/vmcnet
# chown root:root /usr/bin/vmcwebsvc

Testing the installation

Edit the VIRL configuration (3node.virl) to remove out below parameters

# nano /usr/share/vmcloud/data/examples/3node/3node.virl

<entry key="import files" type="String">/usr/share/vmcloud/data/examples/3node/router1.p12</entry>

Run the topology from the template

# vmcloud netcreate -v /usr/share/vmcloud/data/examples/3node/3node.virl 3NODE
