Summary: qcow2 images corruption

Initial Comment:
I'm running a 32bit vm under x86_64 AMD host with kvm-74. using raw image all 
works fine, but with qcow2 image I'm able to get deep fs corruption with a disk 
intensive operation like kernel compilation.
it happened every time I tried, and -no-kvm-irqchip didn't make any difference.

I've browsed the archives for hints, but no luck.

Details:
Host (64):
Linux  2.6.26.3 #6 SMP PREEMPT Sun Aug 31 16:00:51 CEST 2008 x86_64 AMD 
Phenom(tm) 9850 Quad-Core Processor AuthenticAMD GNU/Linux
single CPU/quad core.
fs on image partition: XFS

Gentoo ~amd64, kvm compiled on host system.
Guest (32):
Linux  2.6.26.3vm #4 Tue Aug 26 17:29:00 CEST 2008 i686 QEMU Virtual CPU 
version 0.9.1 AuthenticAMD GNU/Linux
Gentoo x86


command line:
kvm -m 1G -drive file=test.qcow2,if=virtio,boot=on -localtime -net 
nic,macaddr=DE:AD:BE:EF:15:5,model=virtio -net tap
fs on image: ext3

kvm-img info of image that show corruption:

image: test.qcow2
file format: qcow2
virtual size: 10G (10737418240 bytes)
disk size: 103M
cluster_size: 4096
backing file: gentoo-i386-virtio.qcow2 (actual path: gentoo-i386-virtio.qcow2)

kvm-img info of working image:

image: gentoo-i386-virtio.img
file format: raw
virtual size: 10G (10737418240 bytes)
disk size: 4.5G

virtio partitions are in use on guest machine

Let me know it other details are needed.

Thanks for any answer.
