HEAT grub commands for CentOS 7 Nova Instance
Using OpenStack HOT (Heat Template), how does one specify a grub command?
In CentOS 7, the network interfaces are named differently than in previous versions.
To revert to "legacy" network device names, one can simply add net.ifnames=0 biosdevname=0
to grub.
Hence I'm asking how to do this with HEAT when booting a CentOS 7 nova instance.
