Hi Pieter,
On 18.04/20.04 that uses netplan you'll need to add the network device (bridge)
before adding the KVM host.
For example:
Install dependencies:
apt-get install bridge-utils
In /etc/netplan/01-netcfg.yaml applying your network specific changes:
network:
version: 2
renderer: networkd
ethernets:
ens3:
dhcp4: false
dhcp6: false
optional: true
bridges:
cloudbr0:
addresses: [192.168.1.10/24]
gateway4: 192.168.1.1
nameservers:
addresses: [1.1.1.1,8.8.8.8]
interfaces: [ens3]
dhcp4: false
dhcp6: false
parameters:
stp: false
forward-delay: 0
Then (as root),
netplan generate
netplan apply
reboot # reboot is optional if netplan doesnot immediate make the changes
Also, newer sshd versions in Ubuntu 20.04 don't support specific ciphers for
CloudStack mgmt server to ssh and setup agent, which you can fix as:
Add these to your sshd_config on the KVM host temporarily before adding the KVM
host in CloudStack:
PubkeyAcceptedKeyTypes=+ssh-dss
HostKeyAlgorithms=+ssh-dss
KexAlgorithms=+diffie-hellman-group1-sha1
Finally restart sshd and add host via CloudStack UI/API.

Subject: CloudStack 4.15 Focal network issue on MAAS
Hi,
Just wanted to check if there is some way to get cloudstack to read the network
information without a /etc/network/interfaces file? The reason being that
Ubuntu MAAS when deploying a host by default uses netplan to configure all
interfaces. All bridges and routes are valid and there is full network
communication but this error pops up when running cloudstack-setup-agent
[Errno 2] No such file or directory: '/etc/network/interfaces'
Current deployment setup
Version: 4.15
Controller: Ubuntu Focal 20.04
Agent: Ubuntu Focal 20.04
