When you specify --hvm, --nographics, then there is no graphical console
configured. The only way of interacting with the guest is via the serial
port, but most OS (CentOS included) will not put a console on the
serial port by default.

To make this work you need to use the --location arg instead of the
--cdrom / -c arg, but still give a path tot he ISO image. THis will
cause it to directly boot off the kernel+initrd. Now also add then
--extra-args flag, with a value  'console=ttyS0' which will make the
serial port the default guest console for install
