I am a Proxmox and networking newb. I'm hoping someone could help me with the configuration for my first client, Ubuntu Server 16, install.
From the VM console I do not seem to be able to successfully ping the gateway, the host, or 8.8.8.8. 'Destination host is unreachable' is always the message returned.
Here are the host /etc/network/interfaces, the client /etc/network/interface, and the client /etc/hosts. Any ideas would be much appreciated.

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
