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. -- Chris Adams <linux at cmadams.net>
