In the latest package of the Versa Director, the cloud-init custom script injection works with ConfigDrive selected in the qcow2 image. To see the change, check :/etc/cloud/cloud.cfg.d/91_versa.cfg file for datasource_list:[ConfigDrive,OVF].

NOTE: The other file format #cloud-config does not work now.

Testing the Script (For Internal Use Only) 

Follow these steps to test the script:

  1. Access the latest qcow2.
  2. Create an image in the OpenStack.
  3. Select the Custom Script tab to create an instance. Enter this script:
    #!/bin/bash
echo “Hello Versa”  >   /tmp/hello.txt


  4. Set ConfiDrive to true in the Custom Script tab.
  5. Check for Hello Versa in /tmp/hello.txt after creating the instance.
  6. Additionally, check the cloud init directory (/var/lib/cloud/instance) for information related to the guest injection files like; user-data.txt, and cloud-config.txt.

Configuring Ethernet Interfaces

Refer to this script to create an ethernet interface in /etc/network/interfaces.d. 

#!/bin/bash
 
readonly ENI=/etc/network/interfaces

cat <<-EOF' > /etc/network/interfaces.d/eth0.cfg
auto eth0
iface eth0 inet static
   address <static-address>
   netmask <subnet-mask>
   gateway <gateway-address
EOF
 
if ! grep -q source $ENI; then
  echo "source /etc/network/interfaces.d/*.cfg" >> $ENI
fi

NOTE: Run this script on system startup (similar to the steps explained in "Testing the Script" section).


This script ensures that the ethernet interface is assigned a static IP address when the VM starts.
