Ubuntu 18.04 Server - setting DNS With Network Bridge
I am trying to configure my Ubuntu 18.04 server's network which uses a bridge because it also acts as a KVM host. Unfortunately I can't seem to get the DNS to work when the bridge configuration is in effect. Here is the file in its current form:
# ifupdown has been replaced by netplan(5) on this system.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
#
#
auto lo
iface lo inet loopback
# Section 1
#auto enp30s0
#iface enp30s0 inet static
# address 10.1.0.236
# netmask 255.248.0.0
# gateway 10.0.0.1
# dns-nameservers 10.1.0.2
# Section 2
# The primary network interface
auto enp30s0
iface enp30s0 inet manual
dns-nameservers 10.1.0.2
auto kvmbr0
iface kvmbr0 inet static
address 10.1.0.236
netmask 255.248.0.0
gateway 10.0.0.1
bridge_ports enp30s0
bridge_stp off
bridge_fd 0
bridge_maxwait 0
If I comment out section2 and uncomment section 1, the server seems to work just fine. However, I can't seem to get the dns working with section 2 no matter what I try, with moving the dns-nameservers line to both the enp30s0 or the kvmbr0 section (or both).
It is worth noting that I have already run sudo apt install ifupdown.
