I am new to proxmox. I have created a VM having the Ubuntu 18.04 template on top of Proxmox OS. The problem is it is not getting connected to the internet. The proxmox server has an active LAN Connection.

$ ping 8.8.8.8
connect: Network is unreachable

$ cat /etc/network/interfaces
# ifupdown has been replaced by netplan(5) on this system.  See
# /etc/netplan for current configuration.
# To re-enable ifupdown on this system, you can run:
#    sudo apt install ifupdown

-----------------------------------------------------------
$ ip a

if it's your Ubuntu virtual machine network interface eth0 there is no set IP address, and of course, you can not connect to the internet. Also, make sure your DHCP network can distribute IP addresses to Proxmox or enter a static address. show the output of those commands: ip link, ip a, ip route
