Hello, We are running openstack mitaka in ubuntu 16.04 and storage back-end is ceph. we have running vms and we want to change from virtio to scsi to support trimming. Tried to change xml configuration file via virsh and works only if you reboot via virsh. when you reboot via nova goes to default virtio driver What is best way to change that in nova/horizon? -- Lomayani -------------- next part -------------- An HTML attachment was scrubbed...
