I retried vgabios with VGA(same as "-vga std") device and found the
problem again.
For wbc.exe, first screen looked nice when loading and screen mess
after about 15 seconds on second screen.
I used qemu 2.1.2 and my command line:
qemu-system-x86_64 \
-m 1024 \
-smp 1 \
-net none \
-enable-kvm \
-hda /home/lyj/qemu/tmp/xp_noqxl.append \
-device VGA,romfile=/root/qemu/seabios/out/vgabios.bin \
-spice port=5900,addr=0.0.0.0,disable-ticketing,seamless-migration=on \
-chardev stdio,id=debugcon \
-device isa-debugcon,iobase=0x0402,chardev=debugcon \
seabios 1.8.1
kernel 3.10.67
Thanks
