deploy and configure proxmox on openVZ vps for deployment of voip servers

A proposal has not yet been provided

let me get this straight... you want to deploy proxmox ve on top of openvz container? i think it is anusual to deploy it in the openvz container, usually it deploy in the barebone hardware. the openvz container using the host kernel of the vps server, in the other hand the proxmox ve is using it own kernel. i don't know if it would be possible but if it's possible it would be performance concern in the vm that on top of the proxmox ve.
