When qemu-dm is using SDL and has the mouse captured, a "xm destroy"
of the VM will cause control of the mouse to be lost. This happens because the
qemu-dm is killed with SIGKILL, so atexit doesn''t run, so SDL_Quit
doesn''t run. Other things could go wrong too -- for example, if the VM
was fullscreen, the video mode probably wouldn''t be reset either.
There was a discussion a few years ago on the SDL mailing list regarding the
ramifications of not calling SDL_Quit. In short, you don''t want to
skip it:
http://www.libsdl.org/pipermail/sdl/2004-May/062400.html
The attached patch sends a SIGTERM instead of SIGKILL. I''ve been using
a variation of this patch since our SLES 10 betas, and I''ve never seen
a case where SIGKILL was actually needed.
Please apply.
