[one-users] 3.4.0 and HISTORY

[Chris Johnston]

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.
