[Xen-devel] qemu disappear when installing windows guest (sdl=1)
Hi, Samuel and Stefano,
When I install windows xp guest on latest Xen, the qemu window
will sometimes disappear at the secondary boot or at the time when
installation has 35 minutes left (sdl=1). This issue doesn''t happen
every time. And if I use vnc to install the guest, the installation
could pass successfully. When the qemu window disappears, I use gdb to
attach it, and get the following call traces:
1) When qemu disappears at the secondary boot:
Program received signal SIGSEGV, Segmentation fault.

[Xen-devel] Re: qemu disappear when installing windows guest (sdl=1)
I tried 6 times to reproduce this bug without any luck. How often does it show up? Did you compile qemu with opengl support and use opengl together with sdl (the default)?

[Xen-devel] RE: qemu disappear when installing windows guest (sdl=1)
I found that it may only happen on some specific platforms, and it may occur every 3~5 times, not so exactly. BTW, I use opengl in default.
