Install CloudStack 4.5.1

Apache CloudStack 4.5.1

Rather than upgrade i have decided to rebuild my CloudStack to version 4.5.1 and thought i would document the installation process.

The Physical CloudStack Environment looks like this:

3 x KVM Nodes
1 x Management Node
1 x NFS Node
1 x Deployment Node

Install Open vSwitch on CentOS

Installing Open vSwitch on CentOS 6.6

I would like to use Open vSwitch on my KVM nodes in my CloudStack deployment. I will download and build the Open vSwitch rpms on my deployment server, which is just a CentOS VM which i use for deploying packages etc.

Create a directory to download the Open vSwitch tar to (You can find the most recent OVS here: http://openvswitch.org/download/):

cd ~
mkdir -p rpmbuild/SOURCES
wget http://openvswitch.org/releases/openvswitch–2.3.1.tar.gz

mkdir -p rpmbuild SOURCES

Cloning a CentOS VM requires network modification

When cloning a CentOS VM the networking will need to be reconfigured. First of all you will probably need to edit the IP settings in ifcfg-eth0:

vi /etc/sysconfig/network-scripts/ifcfg-eth0

But even after this you won’t be able to ping anything on the network. We have made a change to the network so restart the network service. Restarting the network service will return the following error:  “Bringing up interface eth0: Device eth0 does not seem to be present, delaying initialization.”

Device Eth0 does not exist
