UPDATED : Video version of this blog…..found here… http://youtu.be/RDcIIyYK044

So this Shell-Shock stuff is hitting the press quite a bit!

Fncy finding out really quickly if your Red Hat Enterprise Linux 6.5 systems are patched correctly? Even if they are turned off right now? Wow that is clever not even the virtual infrastructure players can do that…I know…its cool. Here it is..

SOAP – SAVON v2 Syntax

 

So for the past few years Savon v1.1.0 has been the default GEM in the appliance. Heres a scoop! In future releases, and the upstream builds have Savon v2.

What does this mean? Well v2 has a slightly different syntax to its connections and function call. Here is a v2 SOAP example:

Placement Profile – Best Fit Cluster using Tags

CloudFORMS has workflows for many different tasks including approval, quotas and placement to name just a few. This blog entry is going to add to the placement category of workflows. A previous post of mine showed how you could place new workloads NOT_NEAR “Workload Placement by Type (Not Near That)” other workloads which I still think is really cool. This placement workflow is quite simple, it matches template tags against cluster tags. Example;

VM ReConfigure Approval Emails

The base automate model does not contain the email methods for the VM Reconfigure approval process, this post gives you this capability.

Ensure your CFME appliance can send a test email from the configuration page. If you get the test email, then continue otherwise keep trying until you do!

Exporting VM (VMware)

This is a really simple export routine for VMware using a custom button.

In an implementation I would maybe wrap this with

  1. A dialog to offer different export locations and naming of the export to include date/time stamp and maybe a checkbox to enable disable the overwrite of existing exports.
  2. Add in the approval system, basically some workloads should require authorisation by a manager to allow the export, we could do this by tag, and capture this in the method.
  3. Some error checking and folder creation stuff in the simple method.

CloudFORMS CFME on KVM

If you so happen to have the VMware OVF version of CloudFORMs CFME, and you want to convert to run on KVM, this is how.

1. If the OVF is zipped, Unzip the appliance image:

$ unzip evm-v5.1.0.4-r.zip

2. Convert each of the 5 disks from VMDK format to RAW:
$ for i in `seq 1 5`; do qemu-img convert -p evm-v5.1.0.4-r/ovf-disk$i.vmdk disk$i.img; done
