On Fedora 20 virtual machines biosdevname command
'Returns 4 if running in a virtual machine.'
This patch:
- Uses the biosdevname command return value to detect if virtual
- Uses /sys/net to get interface names - Might be better solution
- Leaves unchanged the original 'bare metal' case - I wonder what for
though?
Tested with Fedora Cloud image adapted for vagrant-libvirt
Fixes issue #4104
