[one-users] <DEV>_CONTEXT_FORCE_IPV4 disappeard ?

[Javier Fontan]

When OpenNebula finds NETWORK=yes it adds (or substitutes) network
parameters by the standard network parameters that come in variable
form, something like:

  ETH0_IP = "$NIC[IP, NETWORK=\"public\"]",
  ETH0_NETWORK = "$NETWORK[NETWORK_ADDRESS, NETWORK=\"public\"]",
  ETH0_MASK = "$NETWORK[NETWORK_MASK, NETWORK=\"public\"]",
  ETH0_GATEWAY = "$NETWORK[GATEWAY, NETWORK=\"public\"]",
  ETH0_DNS = "$NETWORK[DNS, NETWORK=\"public\"]",
  ETH0_CONTEXT_FORCE_IPV4 = "$NETWORK[CONTEXT_FORCE_IPV4, NETWORK=\"public\"]",

Then it substitutes the variables but when no match is found the
variable is deleted. I think the problem is that you don't have the
variable "CONTEXT_FORCE_IPV4" set in the virtual network template.
