Description of problem:
RHEL5.6 crash during boot.

Version-Release number of selected component (if applicable):
kernel version: 2.6.32-130.el6.x86_64
qemu version: qemu-kvm-0.12.1.2-2.156.el6

How reproducible:
sometimes

Steps to Reproduce:
1. Run commands on host:
grep -q el5 /proc/version && ([ -e /dev/ksm ] && true || modprobe ksm && ksmctl start 5000 50 ) || (echo 1 > /sys/kernel/mm/ksm/run && echo 5000 > /sys/kernel/mm/ksm/pages_to_scan && echo 50 > /sys/kernel/mm/ksm/sleep_millisecs); echo 'never' > /sys/kernel/mm/redhat_transparent_hugepage/enabled

2.start vm with command:
qemu -name 'vm1' \
-chardev socket,id=qmp_monitor_id_qmpmonitor1,path=/tmp/monitor-qmpmonitor1-20110411-111144-vdyn,server,nowait \
-mon chardev=qmp_monitor_id_qmpmonitor1,mode=control \
-chardev socket,id=serial_id_20110411-111144-vdyn,path=/tmp/serial-20110411-111144-vdyn,server,nowait \
-device isa-serial,chardev=serial_id_20110411-111144-vdyn \
-drive file='RHEL-Server-5.6-32-virtio.qcow2',index=0,if=none,id=drive-virtio-disk1,media=disk,cache=none,snapshot=on,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=id4N6P0v,mac=9a:6e:6b:60:81:17,id=ndev00id4N6P0v,bus=pci.0,addr=0x3 \
-netdev tap,id=id4N6P0v,vhost=on,ifname='t0-111144-vdyn',script='scripts/qemu-ifup-vbr0',downscript='no' \
-m 3100 -smp 2,cores=1,threads=1,sockets=2 -cpu cpu64-rhel6,+sse2,+x2apic \
-spice port=8000,disable-ticketing -vga qxl -rtc base=utc,clock=host,driftfix=none \
-M rhel6.1.0 -boot order=cdn,once=c,menu=off   -usbdevice tablet \
-no-kvm-pit-reinjection -pidfile /tmp/vm1-20110411-111144-VSaQ.pid -enable-kvm 

3. kernel panic occur.
  
Actual results:
guest kernel panic during boot.

Expected results:
guest boot successfully.

If you can reproduce it verify that it is still reproducible 1) with ksm disabled, 2) without usb tablet. Note: check only 1 or 2 not both simultaneously.

Hi, Gleb,
I am trying to reproduce this problem as your advice, but seems it will take
a little more time, it's hard to reproduce.

Comment 6 Qingtang Zhou 2011-04-18 07:05:28 UTC

Hi,
I tried to boot RHEL4.9 guest for about 200 times, but no kernel panic occured again.

Why RHEL4.9? The bug title talks about rhel5.6.

Sorry, type error, my fault. I mean it's RHEL5.6.

Closing the bug since it is not reproducible. Reopen if you see it again.
