That makes sense: once the VM's were started with KVM, they will continue to run independently of the processes that started them (nova-*). > I've had similar problems in the past, and typically I had to reboot > all nodes, starting with the control node (lava-cloud01).

For fastmodels, if you put the devices offline in the scheduler before the interruption and put them back online after it's done (i.e. control will still be accepting jobs and queuing them), it should be OK. -- Antonio Terceiro Software Engineer - Linaro http://www.linaro.org
