Install And Set Up KVM On Ubuntu 18.04 Bionic Beaver Linux - LinuxConfig.org


#1

When you pair KVM with a graphical manager like virt-manager, it's extremely simple to use, and it integrates well with your Linux desktop. It's also simple to get VM guests on your regular network through bridged networking. This provides a more seamless experience overall.

In 18.04 - No WiFi after the bridge setup, so no internet.

after following this bridge setup I couldn’t get through to the internet anymore? the network links were all down and there was no default route for traffic

Here’s one netplan config that worked with Ubuntu 18.04 LTS:

network:
version: 2
ethernets:
enp5s0f0:
dhcp4: true
enp5s0f1:
dhcp4: true
bridges:
br0:
interfaces: [enp5s0f0]
dhcp4: true
optional: true

do you access guest host via enp5s0f0 or enp5s0f1? my machine has one interface and i chose static ip address, but once i built bridge between br0 and the ethernet interface (ens2), just as “Brain Law”, i lost internet access.

Use Gnome Boxes dudes. Way easier.

18.04 doesn’t use /etc/network/interfaces but rather /etc/netplan/*.yaml file


#8

ming -> Daniel Cayea

for 18.04 TLS, bridge definition doesn’t work under /etc/netplan. here is the link:

# ifupdown has been replaced by netplan(5) on this system.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:
