[Spice-devel] deadlock / monitor qemu / spice

[nicolas prochazka]

I'm testing with a windows XP sp3 guest ( qxl 0.10 lastest binary version )
, this vm do two reboot

First test, it's ok :

/usr/local/bin/qemu -name PC001 -spice port=11931,disable-ticketing
-soundhw hda -vga qxl -device virtio-serial -chardev
spicevmc,id=vdagent,debug=0,name=vdagent -device

Same test, but in // I do  :

while(true); do echo "" | socat - TCP4:127.0.0.1:10101 ; sleep 1 ; done

Result, vm freeze during first boot or second.
