Hello.

I did it by creating images with vmdk and it worked in the past. I also convert vmdk to qcow2 but my instances stucked at boot. It is weird.

I am trying create instance from vmdk but I have this error:

The image format was claimed to be 'vmdk' but the image data appears to be in a different format.

Before booting an instance you need to convert the vmdk file to a supported format by Openstack (qcow2 for example).
There is tooling for doing that (v2v) or even my team has created an ansible collection to migrate vmdk volume from esxi to Openstack.

My cloud is Openstack 2023.1. This happened when We applied patches for CVE-2024-40767.
