Hi Openstack Discuss,
I have an issue with nova not synchronizing changes between a glance image and it's local image meta information in nova.
I have updated a glance image with the property "hw_rng_model=virtio", and that successfully passes that to new instances created using the updated image. However existing instances do not receive this new property.
I have located the image metadata within the nova database, in the **instance_system_metadata** table, and can see it's not updated for the existing instances, and only adding the relevant rows for instances that are created when that property is present. The key being "image_hw_rng_model" and "virtio" being the value.
Is there a way to tell nova to update the table for existing instances, and synchronizing the two databases? Or is this the kind of thing that would need to be done *shudder* manually...? If so, are there any experts out there who can point me to some documentation on doing this correctly before I go butcher a couple of dummy nova database?
