So, I guess the people who replied didn't read - I tried ttyS0, and that
didn't work.
I did figure out why that doesn't work: when setting up a new VM with
libvirt in F20, if you choose RHEL7 as the guest OS, it gets set up
differently than RHEL6. One difference is that it sets up a virtio
console, instead of a serial console.
First, it doesn't look like GRUB2 can talk to a virtio console.
Second, I guess I'm hitting a kernel bug, because the kernel should be
able to talk to a virtio console (i.e. hvc0). It certainly shouldn't
crash because I tried to use that. The device works after boot (I can
run a getty on it), it seems only the kernel can't talk to it directly
as a console.
