Title:
qemu-1.5.3 segment fault with -vga qxl
Status in QEMU:
Incomplete
Bug description:
execute " qemu-system-x86_64 -enable-kvm -machine accel=kvm:tcg -m
1G -drive file=/dev/sda --full-screen -spice
addr=127.0.0.1,port=5900,disable-ticketing -vga qxl " on shell will
get segment fault after a few seconds if I don't connect to it
with spicec client immediately.
IF excute "spicec -h 127.0.0.1 -p 5900 " immediately !!!! after
the qemu-system-x86_64 execution, then no segment fault happens
and it runs well.
