[Qemu-devel] qemu-1.2.2 black screen when the winxp guest change the resolution |

hello, i reproduce the problem:
when i use qemu-1.2.2 on centos6.3 with spice-0.12.2, run winxp guest like that:
qemu-system-x86_64 -localtime --enable-kvm -spice port=9999,disable-ticketing -m 2048 -smp 2 -vga qxl -drive file=.xp32_full_stable.qcow2
the win32 xp has install the spice-guest-tool-0.3 and the qxl driver works well.
when i change the guest 's screen resolution(1024*768 to 1280*800), the screen lost reponse and black , so i have to kill the qemu-system-x86_64 process.
but when i restart the guest os again, i found the screen has change to 1280*800, yes the new one.
then i run the guest without qxl support like that:
qemu-system-x86_64 -localtime --enable-kvm -spice port=9999,disable-ticketing -m 2048 -smp 2 -drive file=.xp32_full_stable.qcow2
the problem doesn't occur again, change screen resolution ok, though guest supports vga only.
then i install the qemu-1.3.0, and run the same img file just like above with the same command:
qemu-system-x86_64 -localtime --enable-kvm -spice port=9999,disable-ticketing -m 2048 -smp 2 -vga qxl -drive file=.xp32_full_stable.qcow2
well the qemu-1.3.0 works smooth, and the winxp guest changes the screen resolution successfull.
maybe the qemu-1.2.2's qxl support has a bug ?
if anyone is intersting with the problem, i can supply more info, like logs or qcows img(but it is a little big guy), thx very much.
