Dual stack Ceph, KRBD and EFI/TPM problem

Hi guys, I'm experimenting with dual stack Ceph and due to missing support for dual stack in the kernel client I'm currently not using KRBD in the storage config. This works fine for VM storage except for EFI/TPM volumes. It seems as if those disks are always using KRBD, ignoring the storage setting?
 
yes, while we re-use our volume handling stack in pve-storage for those, they are not "real" disks from qemu's point of view (the TPM volume is even handled by a different software/process), and thus cannot re-use Qemu's librbd-based driver.
