Hello

I would like to have assigned the IP address of PVE Host by the DHCP server.

This is the configuration of /etc/network/interfaces:

auto lo
iface lo inet loopback


# The primary network interface
allow-hotplug eno1
iface eno1 inet dhcp
post-up echo 1 > /proc/sys/net/ipv4/conf/eno1/proxy_arp

# For virtual machines and containers
auto vmbr0
iface vmbr0 inet manual
gateway 172.17.0.1
bridge_ports none
bridge_stp off
bridge_fd 0​


When I launch my container, I get this messages in the logs:

The container starts but has not IPV4 network.

I do not have a preference between the default configuration suggested in the docs or one with routed IPs.
What modifications does the network configuration needs to work? I want the IP address of the be assigned by the DHCP server.
