Hi, A better Q would be why do you shutdown a compute node to begin with? I mean if you need you should do so in an orderly fashion basically excavate instances or shut instances down manually, put the compute node in maintenance mode. On rebooting compute node remove it from maintenance mode, turn on instances or migrate them back to this compute node should you need. Od delete them if you wish.
There is this nova option: resume_guests_state_on_host_boot=true But it doesn't delete or shutdown instances but rather turns them on automatically once compute host resumes. which might also work for you, probably not just mentioning it any way. I don't know of an option to stop/delete instance on compute node shutdown. Another option check maybe you could shelve suspended instance and then later delete them. Shelving stops the instance and takes a snapshot of it. Then depending on the value of the shelved_offload_time config option, the instance is deleted from the hypervisor (0), never deleted (-1), or deleted after some period of time (> 0). Note that it's just destroying the backing instance on the hypervisor, the actual instance in the nova database is not deleted. Then you can later unshelve the instance: This might help, but do not if you mess with kvm without updating Nova you might be left haning else where :) https://ask.fedoraproject.org/en/question/8796/make-libvirt-to-shutdown-my-guests-not-suspend/ On Thu, Nov 2, 2017 at 9:03 AM, Chris <cont...@progbau.de> wrote: > Hello, > > When we shut down a compute node the instances running on it get > suspended.
