Hi all,
Has anyone else noticed that HISTORY records are corrupted when there are
simultaneous VM actions? And some actions leave VMs, in particular a fail to
livemigrate, with a bad history preventing a further live migration? It seems
that update_history is failing at least for sqlite.
# onevm create example.vm
This results in a good history record...

# onevm create example.vm ; onevm create example.vm
This results in none of the timers being set in the history record for either
VM.
