Comment 9 for bug 1397130

another way to reproduce this is to start new instances quickly (e.g. create back to back), and then restart libvirt-bin.

and sometimes, just start new instances quickly (w/o restart libvirt-bin)

for example, for host X, if the sleep are commented out, it will normally crash libvirt if this is run to try and rescue the old instances. if the sleep is present it will normally not crash.

#!/bin/bash
host=$1
j=0
for i in $(nova list --host $host --all-tenants | awk '/Shutdown/ {print $2}')
do
    j=$((j+1))
    if [ $j -eq 5 ]
    then
        echo "Wait a bit..."
# sleep 30
        j=0
    fi
    echo "Rescue $i"
    nova reboot --hard $i
# sleep 5
done
