Re: [Qemu-devel] [PATCH] Prevent disk data loss when closing qemu

[Pavel Dovgaluk]

I use qemu under Windows and it has two windows when executes - console and SDL 
ones.
When I close SDL window main loop function terminates correctly, and when I 
close 
console window to terminate qemu then the code after main loop is not executed.

What's the difference of these two method to call bdrv_close_all?

If you close qemu window, the main_loop will return immediately, and call 
bdrv_close_all.
