#StackBounty: #ubuntu #networking #kvm #lxc Networking with KVM and LXC on the same host (hypervisor)

Bounty: 50

I have KVM installed and running [a couple of VMs] on a Ubuntu Bionic (18.04) host.
The bridge interface of KVM is br0, configured like:

auto br0
iface br0 inet static
      bridge_ports p1p1
      bridge_stp off
      bridge_maxwait 0
      bridge_fd 0
      address 10.192.10.4
      netmask 255.255.0.0
      broadcast 10.192.255.255
      gateway 10.192.0.1

I installed lxc and spun up a few containers. Now I am confused about how to configure
networking for the LXC bridge (lxcbr0) so that the VMs and containers can talk to each
other!

I cannot make br0 the bridge_port for lxcbr0 as it errors
can't enslave a bridge device to a bridge device
I can’t add the interface p1p1 – that would throw p1p1 is already a member of a bridge

Any help/hints much appreciated.

Any static route if I can add specifically for the container IP, that is also fine.

Thanks.
