You can do the same with KVM right now. Just install a different kernel
on Ubuntu or CentOS and that works.

The Ceph integration is only to talk to Ceph and that's all handled by
Qemu+libvirt+librbd+librados.

zvols is nice, yes! But that would be a matter of integrating this into
libvirt. Because then we could also use LVs for storing data and not
only zvols.

I have used Proxmox many times where people wanted a Hypervisor, nothing
more.
It serves it's own purpose imho, not to be controlled by CloudStack. If
you want a no-nonsense hypervisor which just runs VMs: Go with Proxmox!
If you want something which manages networks, templates, firewalling,
ips: Go with CloudStack!
I don't see much benefit in talking to Proxmox with CloudStack because
in the end you are just talking to KVM.
