Re: [Openstack] [OpenStack] [nova] How can I release PCI device resources without delete instance?

Hi, now I got another problem. I have two models of GPU devices and I set both in pci_alias and pcli_passthrogh_whitelist on controller and compute node(with this two GPUs). Now I removed one of GPU and delete its data in nova.conf, then restart nova-api, nova-scheduler (Controller) and nova-compu

As a stop gap for the IP problem, keep in mind that you can create a neutron port separately and boot the instance to it. Then when you delete the instance the port will remain and hold onto the IP so you can boot to it with a different instance later. On Jul 5, 2017 18:31, "Eddie Yen" wrote: >

Hi, thanks for reply first! After I tried shelve instance, yes it really release GPU resources. But as Dinesh said, can't unshelve this instance if all GPUs occupied. Before known about shelve instance, I have do few approach. One is using "resize" the instance's flavor to non-GPU flavor, but ca

Hi Eddie, One way to do this is to “shelve” the instance which will allow to use your PCI device for other instance. But you won’t be able to “unshelve” the previous instance until you delete or unshelve the newly created instance. NOTE: Shelving will release all the resources associated to tha
