Hi I remember I had problems in the past trying to resize or migrate instances launched using an image that was then deleted (I use kvm as hypervisor). This is indeed confirmed e.g. here: https://storyboard.openstack.org/#!/story/2004892 https://docs.openstack.org/operations-guide/ops-user-facing-operations.html#... Now I am not able to reproduce anymore the problem, i.e.: 1- I create an image 2- I launch an instance using this image 3- I delete the image 4- I migrate the instance (nova migrate <uuid)) and this works. Does the migration issue happen only in some particular scenarios ? My current setup: - OpenStack version: Rocky - CenOS 7.x - qemu-kvm-ev-2.12.0-18.el7_6.5.1.x86_64 - /var/lib/nova/instances not shared amomg compute nodes Thanks, Massimo
