This is a question that came up which made me wonder why does the enterprise really need an open source cloud platforms like Openstack, CloudStack, Eucalyptus, etc. What I tend to hear is that our IT needs to be more like AWS, Rackspace or Azure but what does that really mean? When I dissect that response here is what I think about the open source cloud platform question in the enterprise. I make these statements purely from my experience and by defining the “enterprise” as the internal organizations of a business.
The new year has come and most people are making there resolutions clear as to what they plan on doing this time around. For some it may be a repeat of the old with small tweaks and for others a huge overhaul is needed in their life. I know you probably don’t want to read another persons goals for the new year but if you keep reading on that’s exactly what your going to get.
Need to leverage Active Directory (AD) authentication in CloudStack? Well here’s how it can be done. I much simpler in 4.2 than it used to be and can be configured from the management portal. One of the only complaints is that you’ll still need to create an account in CloudStack then map an attribute from those accounts to an AD attribute. Let’s get started.
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 I had this issue and wanted to post how I was able to fix it, if not to help someone else who may be faced with this problem, to help me remember if I run into it again. The error is show below. “An error occurred while trying to retrieve a list of virtual switches” which doesn’t really mean much in helping you solve the problem.
This tip will come in handy when needing to figure out what link to use for downloading the right SystemVM for you environment. This especially useful during the installation and setup phase. I have posted a couple of installation processes and this was not included but take this in consideration given things change rapidly with open source software.
If you or your customers use the cloudstack management UI primarily when working with the cloud infrastructure and/or instances, there’s some pleasant fixes and functionality. CloudStack 4.2 brings a lot of changes but I wanted to point out a few of the notable ones in the UI.
So I have been struggling with the idea of getting to know Openstack in-depth because previous attempts quickly made me realize that it wa..
CloudStack 4.2 is ready for release but the site has not updated so that you can just update your repo and install or upgrade so in this post I’ll go thru the process I use to compile from source. You can use this process for other versions but some things may change. You could also follow the process on the Apache Cloudstack documentation website but this is a slim down version to get you quickly moving with 4.2.
