Open Stack

Hi everyone, I want to ask about the image operating permission &
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.
