Hi Mario, first of all you may be better off just configuring untagged bridges on top of your NIC and let CloudStack take care of VLAN tagging - I.e. if you don’t have the suggested VLANs 100/200/300 already configured and in use they don’t make sense.
With regards to networking you configure your bridges with ovs-vsctl etc., then match these settings in your /etc/network/interfaces. When the host is added to CloudStack the management server will take care of configuring additional tagged ports on the OVS switches to allow your guest VMs / System VMs to communicate on the right VLANs. The most important part is to make sure your CloudStack zone networking has the correct KVM traffic label for each type of network, i.e. these have to be configured with “cloudbr0” etc. depending on what you called your bridges.
