Certain software requires hardware UUID for licensing purposes. When moving a physical machine to a virtual one, the hardware unique identifier is changed causing the software licensing to fail. The solution is to manually override it on a virtual machine if the virtualization environment permits it. Here's how this can be done in Hyper-V and ProxMox KVM.

We have recently started using Hyper-V technology to virtualize our Web servers that are located in hosting facilities all around the world. During this process, we have learned a few tricks that might be useful in your next virtualization scenario.

We started using the ProxMox Virtual Environment for various Linux and Windows systems in our company and wanted to virtualize our Redmine TurnKey Linux appliance. We could have done it via KVM, but wanted to explore the option of using another virtualization method in ProxMox - OpenVZ container virtualization, which should have a better performance and utilization of machine resources.

Mono is not all about MonoX, eCTD and ASP.NET development. This article is the first one in a series describing the other topics we are dealing with on a daily basis. Due to various virtualization needs in our company we have initially started using the Microsoft Hyper-V. However, all the Linux solutions were are using and designing made us look the other way, just in time to find a hidden gem in the virtualization land.
