CloudStack Deploy is a utility for making Apache CloudStack and KVM installations quick, easy and painless. Meant to be reusab..
I wrote a post awhile back about using node.js, ansible, and python to do my apache cloudstack installation. Ansible is great but I basically used python to make using ansible a bit more easy since there are a few things with any ansible setup which needs to be remembered. One of those things is the ansible hosts that gets used.
This might be a strange combination but I was looking for an easier more repeatable way of installing and setting up the foundational comp..
If you have every created a linux virtual machine template you’ve probably experienced the issue where a new ethernet device would be created on each VM instance created from that template. For those that have not found the resolution to this problem are in for a treat if your working with CentOS or RHEL. All thats needed is to delete the “/etc/udev/rules.d/70-persistent-net.rules” file right before you shutdown the vm and make it a template.
The tip I have for you this time is to use CloudStacks interface for accessing meta-data about you instance from within the instance. It’s very simple to use and can be very useful. In this tip I’ll show how you can use the meta-data to rename a CentOS 6.4 linux instance automatically after it is created. But first lets introduce the meta-data interface for CloudStack.
So lets configure NIC Teaming in Powershell now.
Installing updates, extensions, and upgrading esx is very easy with vSphere Update Manager and here is one way how it can be used to install EMC PowerPath/VE. The same process can be used to install other extensions but lets stay focused. PowerPath/VE is used to optimize storage i/o and automate path failures. It aids in making your environment more robust for those business critical applications. As I write this, I’ll assume that you vSphere Update Manager and plugin has already been installed and setup.
Here is a simple powershell script to collect some esx host information (Name, Version, Build, Manufacturer, Model, Cpu Count, Core Count, ServiceConsole IP, and Vmotion IP). This is a modified script I originally found in the vmware community.
The app scans the homedir directory you choose and checks the name of the homedir folders to accounts in AD. For this to be useful the homedir folders should have the same name as the users logon. I created this tool for file server cleanup of old, none used data and homedirs after the Active Directory users have been disabled or deleted. Our file servers are always running into space issues so being able to reclaim space quickly and remove old employee data helps reclaim space that would other wise be wasted.
