Description Francesco Romani 2014-12-16 16:11:54 UTC

Description of problem:
During an automated test of oVirt involving automated migration of some VMs, libvirtd crashed.

Logs and coredump attached.

How reproducible:
Not really sure. Seems more likely with consecutive migration, but failed to find a common cause yet.

Steps to Reproduce:
1. run 5 VMs on a node
2. migrate all of them at the same time
3.

Actual results:
In still unclear circumstances, libvirt crashes

Expected results:
No crash

Looking at the stacktrace.txt:

This is the same crash as in bug 1162208 and bug 1171124
