Why does Red Hat Enterprise Linux 7 anaconda not create physical parent network interface file if it was installed with trunked child interface ?

Issue

• Let's say if the interface available in the system is named as eno3 and we are creating a vlan interface with id 303 on top of that on anaconda command line, the interface config file /etc/sysconfig/network-scripts/ifcfg-eno3.303 gets created but not the file /etc/sysconfig/network-scripts/ifcfg-eno3.
• This doesn't stop the installation, but when tried installing Red Hat Enterprise Virtualization on such hardware, that fails with error as follows.

IOError: [Errno 2] No such file or directory: '/etc/sysconfig/network-scripts/ifcfg-eno3'

• And simply, following thing resolves that problem.

# touch /etc/sysconfig/network-scripts/ifcfg-eno3

• Anaconda should create both the files i.e. ifcfg-eno3 as well as ifcfg-eno3.303 even if installation doesn't fail, because having this file created makes RHEV installation error free at least for this config.
