Implementation is against my PVE setup, expect to see, some time in the future, a capable OpenStack Horizon-alike dashboard for PVE. Non-exhaustive list of features planned, implemented, or on the radar:

• Provide proper project management capabilities (detached from PAM or PVE authentication)
  • Projects (can be created and disposed as required)
  • Groups (Combine users, and assign per project privileges to groups)
  • Users
  • Requires only one pve-user for the Proxmox Cloud-VM with Administrator privileges
• Cluster-wide auto migration/load balancing of VMs
  • LXC not supported 1
• QEMU management and user provisioning
• OpenStack-like configuration:
  • Nova Flavors
  • Neutron provider, project and user-provisioned networks
    • Features unsupported by OpenStack (upto) Xena: QinQ over 802.1q
  • Glance Images
  • Cinder Volumes
• RHV/oVirt-like global cluster options
  • CPU Model for VMs
• Image management on Ceph RBD
  • This will bypass PVE ISO template management for CephFS, using straight snapshots/clones.
• Storage Management, Ceph only
• Volume management on Ceph RBD
• Image/Template management
  • Using Proxmox Templates is no requirement,
    if I can work around Proxmox Templates, I will.
• HA for VMs
  • ? Automatic (cloud-wide)
  • ? Manual (configurable by user)
• One-Way migration of already existing cluster resources (VM, SDN Network) to Proxmox Cloud
  • If possible renaming SDN Zones and VNets will happen for easier management in Proxmox Cloud
• VM description containing CommonMark description

Proxmox Cloud won't be a cluster management platform, as the PVE Web GUI is already well-suited for this job.
This will be a self-service cloud-like platform on top of PVE.

Currently I cannot accept any help, as I'm still figuring this out.

Though these parts will be left open, unless I find myself needing these in my deployment:

• SDN-features, except
  • Simple
  • QinQ tunneling over 802.1q
  • VLAN
  • VXLAN
• Storage-management, except
  • CephFS (LXC Root FS)
  • Ceph RBD
• Backup
• Replication
• ACME
• Firewall
• Permissions (unless already implemented by internal identity support)
