Hi,
I tried this with a current (git) build, and I'm not able to reproduce
it.
I do see a problem with a bad initial SDL window size (its much too
small) on a remote machine over a moderate-level network (wireless LAN).
I don't see that when ssh-ing to localhost (even though both hosts are
basically the same).
I do see differences between current (git) qemu and the 0.12.5 version.
Current git boots the ISO, but doesn't appear to get to the login
screen.
I'm not sure what the differences between our configurations are. I have
SDL 1.2.14-6ubuntu3
Still investigation.
Brad

Title:
qemu/kvm SDL over ssh -X broken
Status in QEMU:
New
Bug description:
qemu/kvm by default uses SDL to render the output of its emulated VGA
graphics.
This is broken over ssh -X since quite a while.
The only workaround I know, is to use qemu -vnc :0
and connect using vncviewer
How To Reproduce:
1. zypper in qemu
2. ssh -X localhost qemu -cdrom ANYISOFILE
Actual Results:
qemu hangs in an endless loop on the BIOS display screen
Expected Results:
should boot up the iso as 0.10 versions did
Reproducible: Always
this is what broke it:
$ git bisect bad

sdl zooming
Hi all,
this patch implements zooming capabilities for the sdl interface.
A new sdl_zoom_blit function is added that is able to scale and blit a
portion of a surface into another.
This way we can enable SDL_RESIZABLE and have a real_screen surface with
a different size than the guest surface and let sdl_zoom_blit take care
of the problem.
