When a NIC is detached, its ETHx_* variables are removed from the VM CONTEXT whatever the value of NETWORK is. With NETWORK=NO, OpenNebula does not generate those variables: they are defined by the user, and nothing generates them back when the NIC is attached again. Guests that read their network configuration from the CONTEXT at every boot lose their network. Only clear them when NETWORK=YES, the same condition generate_network_context() uses to decide whether OpenNebula manages them.
