I get the same error under very similar conditions:
Host is Athlon II X3 400e (triple core), host OS is my own DIET-PC
embedded platform, 2.6.34.1 x86_64 kernel with x86_64 userspace. Qemu-
kvm compiled myself from official qemu-kvm-0.14.0 sources Debian Lenny,
against spice / spice-protocol 0.6.4, using:
export CFLAGS='-O3 -m64'
./configure --prefix=/usr/local --enable-mixemu --disable-brlapi \
--disable-vnc-tls --enable-system --disable-linux-user \
--disable-curses --audio-drv-list="oss sdl" --enable-io-thread \
--disable-vnc-png --enable-vnc-thread --enable-spice \
--audio-card-list="ac97 es1370 sb16 cs4231a adlib gus hda" \
--target-list="i386-softmmu x86_64-softmmu arm-softmmu mips-softmmu
mipsel-softmmu ppc-softmmu ppc64-softmmu sparc-softmmu sparc64-softmmu"
Guest is Windows XP SP3 (uniprocessor), crash with exact same error as
above occurs when attempting to install qxl 0.6.3 spice driver on the
guest. Guest has no virtio-serial or vdagent, but has viostor and
virtio network drivers.

Title:
qemu-kvm-0.14.0 Aborts with -vga qxl
Status in QEMU:
New
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.
