Hi, I am trying to deploy CloudStack 4.0.2 on a small cluster, using CentOS 6.3, the KVM hypervisor, and a Basic Zone configuration. I do not have previous experience administering VMWare or XenServer, just end-user experience with AWS. I have read the Quick Install Guide, the Installation Guide, and most of the Admin Guide.
I brought the Management Server up, with the help of the Tutorial "setup checklist" and the Installation Guide. Now I'm working on the Host installs. However, I am confused by section 8.1.7 of the *Installation Guide<http://cloudstack.apache.org/docs/en-US/Apache_CloudStack/4.0.2/html/Installation_Guide/hypervisor-kvm-install-flow.html#hypervisor-host-install-network> *, "Configure the Network Bridges" (for KVM Hypervisor Host Installation). Section 8.1.7 and 8.1.7.2.1 (for CentOS) state that ALL installations must create three VLANs on each KVM host server. But this isn't mentioned in the Quick Install Guide nor the Admin Guide. Nothing says how these VLANs are used by the services, or how to declare them to the Management Server. Therefore it is hard to see how to adapt the instructions in 8.1.7.2.1 to my environment. Some other doc sections talk about VLANs, but only in the context of VMWare or XenServer, which we aren't using. Furthermore, my IT colleague says these servers are already on a VLAN, and he's very concerned about CloudStack creating its own VLANs that may conflict or overlap. Is it truly necessary to set up these three VLANs for a Basic Zone configuration with KVM? If so, can you point me at any more documentation about how the Virtual Routers use these VLANs in a Basic config? And do you have any guidance for working with systems that already have their primary IP communications going through a VLAN? Thanks in advance for your help. --Matt
