Hi
>deploy and configure proxmox on an open VZ VPS with firewall( pfsense or comparable for the deployment of asterisk or freeswithch.
I have 3 proxmox clusters installed with drbd mirrors. I use both KVM and VZ. pfsense is based on FreeBSD and it can be run only in KVM, not in VZ container. I use iptables inside VZ container, but not proxmox's firewall, because it is not fully capable to do all that things that iptables do.
