[Qemu-devel] [Bug 723871] Re: qemu-kvm-0.14.0 Aborts with -vga qxl

apt-get install gobject-introspection libgirepository1.0-dev

./configure --prefix=/usr --build=x86_64-linux-gnu \
 --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share \
 --sysconfdir=/etc --localstatedir=/var --libexecdir=/usr/bin \
 --with-python --disable-static --enable-introspection

. . . . . .

        Spice-Gtk 0.6
        ==============

        prefix:                   /usr
        c compiler:               gcc -std=gnu99
        c++ compiler:             g++

        Coroutine:                ucontext
        Audio:                    pulse
        Target:                   
        SASL support:             yes
        Gtk:                      2.0

        Now type 'make' to build spice-gtk

make
checkinstall  --install=no
dpkg -i   --force-overwrite  ./spice-gtk_0.6-1_amd64.deb

Libraries and binaries been overwritten are exactly the same as before.
Spice session via Virt-Manager ( video "qxl")  is manageable via keyboard
before logging in (F14,Natty VM's). Mouse pointer appears and works stable
during all the time after login.

Title:
  qemu-kvm-0.14.0 Aborts with -vga qxl

Status in QEMU:
  Invalid
Status in “libvirt” package in Ubuntu:
  Triaged
Status in “qemu-kvm” package in Ubuntu:
  Fix Released

Bug description:
  Host CPU is Core i7 Q820.  KVM is from 2.6.35-gentoo-r5 kernel (x86_64).
  Host has spice-0.7.2 and spice-protocol-0.7.0.
  Guest is Windows XP SP3 with qxl driver 0.6.1, virtio-serial 1.1.6 and 
vdagent 0.6.3.

  qemu-kvm is started like so:
  qemu-system-x86_64 -cpu host -enable-kvm -pidfile /home/rick/qemu/hds/wxp.pid 
-drive 
file=/home/rick/qemu/hds/wxp.raw,if=virtio,media=disk,aio=native,snapshot=on -m 
768 -name WinXP -net nic,model=virtio -net user -localtime -usb -vga qxl 
-device virtio-serial -chardev spicevmc,name=vdagent,id=vdagent -device 
virtserialport,chardev=vdagent,name=com.redhat.spice.0 -spice 
port=1234,disable-ticketing -monitor stdio
  and crashes with:
  qemu-system-x86_64: /home/rick/qemu/src/qemu-kvm-0.14.0/qemu-kvm.c:1724: 
kvm_mutex_unlock: Assertion `!cpu_single_env' failed.
  Aborted

  If I use -no-kvm, it works fine.  If I use -vga std, it works fine.
  -enable-kvm and -vga qxl crashes.
