Install guide for KVM + Cloudstack +Centos 6.x

["Jake G." <dj...@yahoo.com>]

Hi all,

Ive been trying to follow the documentation for Cloudstack with a KVM host, but I am having a hard time following as the official docs jump around alot.
Anyone have a easier to understand install doc/blog/wiki that you have used for KVM? Also, is openvswitch required with KVM?


Some questions I have:
1. Were do I install the CS management server? Can it be on a VM created on the KVM host?
2. Is openvswitch required?
3. What if I am not using vlans and alias on my host`s NICs? what should my NIC config look like? Do I need to create bridges named cloudbr0 and cloudbr1 for the below NIC 
--Current settings--
eth0: 192.168.100.131/24 GW 192.168.100.254 is for public access (internet access)
eth1: 10.3.9.50/8 no GW is for management access


4. on the add cluster area, what if I only have one KVM host? What would my cluster name be?


Thank you!

Hello Jake,

1) You can install the Management server where ever you like as long as it has access to the compute hosts. You _can't_ initially install it on the KVM host as a VM since you can't have any existing VM's before you add a host to CloudStack (they wont be recognized since they weren't created through CloudStack). Since you can setup your Management server as a highly available configuration you could create your Management server VM after your initial setup, you just have to move the database over. That's got a lot more detail involved that's not really key to your initial setup and could be addressed later.

2) No, you don't have to use openvswitch and using KVM the default is to use bridged networking.

3) If you aren't going to use VLANs you'll want to configure your zone with Basic networking. Basic networking is flat, so everything will be in the same IP space. You just have to take care to not overlap any IP ranges assigned to things. Pretty sure the Management server does a good job a preventing overlaps. This link should get you going for network config on CentOS. Adapt it for Ubuntu if you're using that instead:

http://cloudstack.apache.org/docs/en-US/Apache_CloudStack/4.1.1/html/qig/chap-qig-Environment.html#sect-qig-Environment-operatingsys-network

4) You can have just one host in a cluster, and you can name it whatever you want.
