Title:
  qemu/kvm SDL over ssh -X broken

Status in QEMU:
  Fix Released

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:

  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.

2011-04-12 Thread Bernhard M. Wiedemann 
I now found that it depends on my client side. The bug happens when I ssh -XC 
from my netbook with 1024x600(intel)  to a server, but when I ssh -XC to the 
same server from my laptop with 1024x768(fbdev), then it works.
So might be that the scaling code that made the difference in my bisecting, is 
only used for small screens.

[Qemu-devel] [Bug 691424] Re: qemu/kvm SDL over ssh -X broken

2011-04-08 Thread Brad Hards 
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

One possible way to get X11-forwarding back on qemu master is to disable
zoom by this patch.

But I do not know why the do_sdl_resize function should be problematic.
There is probably a better solution.
