Windows images issue we met since we can't find any answers on the 

internet.

1. Now we're still using Rocky with Ceph as storage. Sometimes we 

need to re-pack the image on the Openstack. We used to save as 

snapshot (re-pack by Nova ephemeral VM) or upload to image (re-pack 

by volume), then set snapshot/image's visibility to the public. But since

Rocky, we can't do this anymore because when we try to set public,

Horizon always shows "not enough permission" error. 

The workaround we're using for now is creating a nova snapshot after

re-pack, download the snapshot, then upload the snapshot again as 

public. But it's utterly wasting time if the images are huge. So we want to

know how to unleash this limitation can let us just change snapshot to

public at least.

2. Openstack uses virtio as a network device by default, so we always 

install a virtio driver when packing Windows images. As the network

performance issue in GSO/TSO enablement, we also need to disable

them in device properties. But since Windows 10 2004 build (my thought)

device properties always reset these settings after Sysprep. We found 

there's a workaround [1] to solve this issue, but may not work sometimes.

Is there a better way to solve this issue?

Many thanks,

Eddie.
