Description Suqin Huang 2011-07-28 12:19:24 UTC

Description of problem:
run kvm guest, echo 1 > memory.move_charge_at_immigrate, host will reboot auto

Version-Release number of selected component (if applicable):
2.6.32-171.el6.x86_64

How reproducible:
100%

Steps to Reproduce:
1. 
cmd:
/usr/libexec/qemu-kvm -drive file=/root/RHEL-Server-5.7-64-virtio.qcow2,index=0,if=none,id=drive-virtio-disk1,media=disk,cache=none,format=qcow2,aio=native -device virtio-blk-pci,bus=pci.0,addr=0x4,drive=drive-virtio-disk1,id=virtio-disk1 -device virtio-net-pci,netdev=idoq0tcT,mac=9a:5e:b5:68:17:d8,id=ndev00idoq0tcT,bus=pci.0,addr=0x3 -netdev tap,id=idoq0tcT,vhost=on,ifname=t0-205512-G596,script=/home/Auto/autotest/client/tests/kvm/scripts/qemu-ifup-switch,downscript=no -m 2048 -smp 2,cores=2,threads=1,sockets=1 -cpu cpu64-rhel6,+sse2,+x2apic -vnc :0 -rtc base=utc,clock=host,driftfix=none -M rhel6.1.0 -boot order=cdn,once=c,menu=off  -no-kvm-pit-reinjection -enable-kvm -monitor stdio -chardev socket,id=serial,path=/tmp/serial,server,nowait -device isa-serial,chardev=serial
2. mount -t cgroup -o memory none /cgroup
3. mkdir /cgroup/qemu-kvm 
4. echo 1 > /cgroup/qemu-kvm/memory.move_charge_at_immigrate
5. echo pidof qemu-kvm to tasks
  
Actual results:
host reboot
