Failed to Install the Identity Router Virtual Appliance for VMware after committing the network configurations with an error "Error updating httpd.conf".

1st reason is: The RSA IDR virtual machine has a CD-ROM attached.
2nd reason is: The RSA IDR is configured to have only one management interface, and the portal interface is not enabled/configured from the CLI; however, the virtual machine is configured to have 2 interfaces (management and portal interfaces).

• Management IP invalid, and 2 NICs added, but trying to configure 1NIC
  
• 1NIC added, but trying to configure 2NIC
  
• 2NICs added, but trying to configure 1NIC
  
• Management Gateway is out of the subnet range
  
• Invalid Management Gateway
  
• Invalid Management Netmask
  
• Invalid Management IP
  

1. Make sure of the network settings (Management Interface IP Address, Netmask and Gateway).
2. Remove a CD-ROM Drive From the virtual machine.
3. If the RSA IDR is configured to use only one interface (management interface), Delete the 2nd Interface/NIC of the virtual machine.
4. Commit the network configurations again.
