Very nice!
I tried them out - but i'm unsure how to activate the feature.
Right now 'kvm run' will run the guest and it outputs to the serial
console. If i try 'kvm run --sdl' i get:
linux/tools/kvm> ./kvm run --sdl
That's correct.
# kvm run -k ../../arch/x86/boot/bzImage -m 1216 -c 16

What kind of options should i select on the guest kernel image side
to be able to boot via the SDL framebuffer?
That's not related to the SDL code but to the VESA code. I suppose you
never tried the VNC version so you need to make sure the following config
options are there:

kvm tools: Initialize and use VESA and VNC
Requirements - Kernel compiled with:
CONFIG_FB_BOOT_VESA_SUPPORT=y
CONFIG_FB_VESA=y
CONFIG_FRAMEBUFFER_CONSOLE=y
Start VNC server by starting kvm tools with "--vnc".
Connect to the VNC server by running: "vncviewer :0".
Since there is no support for input devices at this time,
it may be useful starting kvm tools with an additional
' -p "console=ttyS0" ' parameter so that it would be possible
to use a serial console alongside with a graphic one.
