Hi Kevin,

I met the same problem and posted in the mailing list like 10 days ago.

You can check the mailing list archive.

Briefly, two points should be kept in mind.

1. the grub should be boot in text mode, disable the framebuffer.

2. the qemu command should be with, -curses -vga virtio
    the -vga virtio is important.  of course, YMMV.

Good luck!

I had downloaded fedora 21 installation iso:

I am trying the following sequence:

qemu-img create -f qcow2 vdisk.img 10G
I use "-curses", as this machine is a server, and X windows is not
installed there:

qemu-system-x86_64 -curses   -hda vdisk.img -cdrom
Fedora-Live-Workstation-x86_64-21-5.iso -boot d  -m 384

 and I am stuck with a black screen with one line on it, in blue: 1024
x 768 Graphic mode.
This screen does not respond to any keystrokes. except for that
  I can toggle to monitor mode with ALT/2, but this does not help at all.

when I tried with "-nographic" instead of "-curses", the installation hangs.

What should I do in able to boot successfully?
