Hi , I am using qemu to experience fodora20 (Fedora-Live-LXDE-i686-20).
After I successfully installed fedora , it runs in 1024x768 mode,
then I tried to set display resolution to 1680x1050 (or some other 'big'
numbers),
qemu crashed.
Here is detail:

================ versions ===========================
qemu version 2.0.0
spice version 0.12.5
guest type Fedora 20 32bit created from Fedora-Live-LXDE-i686-20-1.iso
================ some more info ===========================
I use same qemu/spice to run win7_64b guest with spice-guest-tool-0.3
installed, and that is OK.
No crash happens while display reolution switching.
If I change '-global qxl-vga.ram_size=67108864 -global
qxl-vga.vram_size=9437184 '
to '-global qxl-vga.ram_size=67108864 -global
qxl-vga.vram_size=67108864 ',
then no crash but 'black screen' I got.
May I get any debug hint ? :)
Thanks in advance.
