Hi Benjamin,

Take a look at a blog article I did a couple of years ago - it will give you a fair bit of
background on how to configure KVM:

A few pieces of advice:
- Unless you have some very specific networking requirements don't use a separate VLAN for
storage - just run with the default which will run secondary storage traffic over the management
- Guest VLANs 2000-2699 - no problem - just make sure your top of rack switches can handle
that amount of VLANs - most of them will do. Also keep in mind you need to run this on trunks
- CloudStack manage the VLAN tagging for you.
- Public VLANs: unless you plan to run a large amount of public networks you don't need such
a big range - most organisations start with 1 public VLAN 
- iSCSI primary storage traffic is not managed by CloudStack - so all you need to do is make
sure the KVM hosts can speak to your storage.

    Hi together,
    currently we have a cloudstack 4.10 environment with Xenserver and the following network
    Physical (Bond) Interfaces:
    1 management -> untagged vlan for management / tagged vlan 133 for secondary storage.
    2 guest -> tagged vlans 2000-2699
    3 public -> tagged vlans 200-250
    4 ISCSI -> untagged
    I am now on eval for using KVM in this environment.
    I am also new to KVM.
    My question is how do i have to setup the cloud bridges for using this network layout
on KVM. And How do i have to name the cloudbridges in KVM ?
    Kind regards Ben
