Proxmox VE is a bare-metal hypervisor that provides OpenVZ containers as well as KVM full virtualization.
OpenVZ is a high-performance and easy to use virtualization platform.
An OpenVZ template for PIAF is available for simple installations.
For a static guest IP address, choose Virtual Network (venet) when creating the VM.
If you choose a Bridged network where an IP comes from your DHCP server, you'll need to add a file:
/etc/sysconfig/network-scripts/ifcfg-eth0
Make it look like this:
DEVICE=eth0 BOOTPROTO=dhcp DHCPCLASS= ONBOOT=yes
In addition, there is a problem with /etc/sysconfig/network. Edit the file using the actual hostname of your machine so that it looks like this:
NETWORKING="yes" NETWORKING_IPV6=no HOSTNAME="whateveryourhostnameis"
Then:
service network restart
