It is actually easier when you consider a typical proxmox cluster with
openvz and kvm machines and recall that openvz currently requires
simfs (btw: ploop is out of beta not and could be supported too).
In a small cluster that runs a mixed load, there is no space for
allocating entire disks to ceph. There is no need for that too. The
key here is small: 3 to 6 nodes total.

Following the same reasoning I could use openvz and kvm+qemu without
proxmox at all. I have done this is the past, but shall I do so now?
What I am talking about is making proxmox a better fit for a more
Che choice to limit osd to physical disks when there is no such
limitation in the underlying technology is a plain arbitrary choice
(political choice if you wish) which is actually removing from the
potential customer base and not adding to it.
I really do not understand.
