@olivierlambert busy writing/adapting de RBD SR and running tests. once I got the results and thins finalized I'll post and update with the RBDSR file (based on @benapetr)

@olivierlambert I backported recent libceph/rbd/krb5 support to the xcp 8,3 kernel to support the new ceph authx aes256k method and include more rbd image features. I've added the rpms which install these newer versions as alt and extra modules and can be removed again as well. although I did run test on it I would suggest people to take caution and do not test in PROD

https://imirc.nl/xcpng/krb5-module-1.0.0-1.xcpng8.3.x86_64.rpm
https://imirc.nl/xcpng/libceph-module-alt-1.0.0-1.xcpng8.3.x86_64.rpm
https://imirc.nl/xcpng/rbd-module-alt-1.0.0-1.xcpng8.3.x86_64.rpm

If anyone else is interested / has feedback please do let me know!

Kind regards
Tim

So far update from XS7.2 to XCP-ng 8.0.0RC1 went fine on Intel E5430.
