Comment 21 for bug 1643911

@ChristianEhrhardt:

I can success reproduce this issue on my environment, the issue can be reproduced by stop and start multiple instance parallelly (in my case is 5 cirros instance)

I have try both PPA, the PPA-2619 fix this issue, stress 7 days and libvirt work fine, but PPA-2620 still hit libvirt crash issue

Below is my test script, the time to hit the issue is about 2 hour ~ 12 hour, libvirt will crash due to memory corruption

vm instance is created by command "openstack server create --image cirros --flavor m1.nano cirrosX", X=1~5

#!/bin/bash

TEST_ROUND=3000

for round in `seq 1 1 $TEST_ROUND`; do

echo "test round $round ..."

for i in `seq 1 1 5`; do
        openstack server stop cirros$i &
done

sleep 1

for i in `seq 1 1 5`; do
        while true; do
                STATUS=`openstack server show cirros$i -f value -c OS-EXT-STS:power_state`
                if [ "$STATUS" == "Shutdown" ]; then
                        break;
                fi
                sleep 1
        done
done

for i in `seq 1 1 5`; do
        openstack server start cirros$i &
done

sleep 1

for i in `seq 1 1 5`; do
        while true; do
                STATUS=`openstack server show cirros$i -f value -c OS-EXT-STS:power_state`
                if [ "$STATUS" == "Running" ]; then
                        break;
                fi
                sleep 1
        done
done

done
