VSphere | Advanced snapshot trobuleshooting - Part 3 - Example: Invalid snapshot configuration

Unable to consolidate because of invalid snapshot configuration

This is Part 3 of the short tutorial series:
vSphere | Advanced snapshot troubleshooting

This is much more advanced than our previous example.  You will see these two errors if you attempt to consolidate, clone or migrate the VM:

Detected and invalid snapshot configuration

or

I am writing this article as an extension to my previous post A VM is showing disk size of 0B where I will attempt to make a general explanation on how to troubleshoot and successfully solve snapshots and consolidation problems in your vSphere with a number of examples. Because the general article was so big, I decided to split it into three parts. This Part 1, is where I am describing the commands which are used to solve most of the snapshot problems and in the next two parts I will describe the process of troubleshooting via examples.

CentOS V2V | Hyper-V to VMware - The easy way

I had a task to export a Hyper-V, CentOS 6 VM and deploy it to a vSphere cluster. Due to the nature of the VM we had to preserve it because the VM was already set up and it was too long for us to build a new one with the same settings.

Before start I would like to point out that if this is a Linux VM you are doing, then because there will be a complete hardware change you may end up with unbootable clone, which can be fixed. This did not happen to me though, but in the end of this article I will also point those things out as potential issues.

Virtual disk configuration change detected, resetting CBT failed Details: A general system error occurred: 
Creating VM snapshot
