[ovirt-users] SQL : last time halted?

Hello, I'm trying to find a way to clean up the VMs list of my DCs. I think some of my users have created VM they're not using anymore, but it's difficult to sort them out. In some cases, I can shutdown some of them and wait. Is there somewhere stored in the db tables the date of the last VM exctinction? Thank you. -- Nicolas ECARNOT
