Version-Release number of selected component (if applicable): kvm-83-232.el5 kernel 2.6.18-259.el5 How reproducible: only once Steps to Reproduce: 1. create a snapshot #qemu-img create -b RHEL-4.9-64.raw -f qcow2 sn1.qcow2 2. boot up new created sn1.qcow2 with cmd ******** cmd line ******** #/usr/libexec/qemu-kvm -drive file='sn1.qcow2',index=0,if=ide,media=disk,cache=none,format=qcow2 -net nic,vlan=0,model=e1000,macaddr='9a:ee:93:df:01:06' -net tap,vlan=0,ifname='t0-091953-J5dh',script='qemu-ifup-switch',downscript='no' -m 32768 -smp 8,cores=1,threads=1,sockets=8 -cpu qemu64,+sse2 -soundhw ac97 -spice port=8000,disable-ticketing -qxl 1 -rtc-td-hack -M rhel5.6.0 -boot c -usbdevice tablet -no-kvm-pit-reinjection ************************** 3. create big file in guest #dd if=/dev/zero of=/tmp/file_sn1 bs=1M count=1000 4. shutdown guest #shutdown -h now Actual results: guest kernel panic Expected results: guest shutdown normally Additional info: Tested 20 times, hit this bug only once.
Doesn't look related to the snapshot at all. I suspect this was only a coincidence. Golita, did you experience the problem again since then?
No response, so I'm assuming that it really happened only once and is most likely unrelated to qemu. Closing.
