Cloonix : Another userspace for KVM

Cloonix KVM is an alternative userspace for KVM designed specifically for simple realtime network topology management.  The killer feature of Cloonix is a GUI WYSIWYG tool that allows you to drag and drop elements in a network topology.  These elements include virtual machines, routers, LAN interfaces and sniffers among others. Networking uses a rewritten slirp userspace library so performance is not great but this is the tradeoff for the convenience of modifying your topology in real time in a graphical way.

phpVirtualBox

An open source, AJAX implementation of the VirtualBox user interface written in PHP. As a modern web interface, it allows you to access and control remote VirtualBox instances. Much of its verbage and some of its code is based on the (inactive) vboxweb project. phpVirtualBox was designed to allow users to administer VirtualBox in a headless environment – mirroring the VirtualBox GUI through its web interface.

NoMachine NX

NoMachine NX is a fast terminal server and desktop virtualization system based on the X11 protocol. NX is an order of magnitude faster than VNC or X11 and can run on bandwidth as narrow as 10 kBit/sec. In addition, NX translates and embeds the MS Windows Terminal Server and VNC protocols into X/NX, enabling users to compress and accelerate remote Windows and VNC sessions.

Is VDI Really an Option?

For those of you who’ve followed along on my virtualization posts, you’ve noticed that I’m a fan of certain types of virtual desktop infrastructure implementations. This was not always the case. In fact, if you Google my name and VDI, you’ll find that for most of the past three years, I’ve come out strongly against it. So, you’re probably asking, “Why the change of heart?” The answer is simple, it’s a matter of timing and technology. VDI really was not an option before but it is now.

Spice – Open Source VDI

The Spice project aims to provide a complete open source solution for interaction with virtualized desktop devices.The Spice project deals with both the virtualized devices and the front-end. Interaction between front-end and back-end is done using VD-Interfaces. The VD-Interfaces (VDI) enable both ends of the solution to be easily utilized by a third-party component.

StarWind free V2V Converter

StarWind Converter is a downloadable V2V conversion tool for virtual machines. You can use it to convert VMDK to VHD files and VHD to VMDK as well as to IMG file, which is a native StarWind format. This is a very simple but useful file conversion tool that will convert virtual hard drive images from VMware’s VMDK format into the Microsoft’s VHD format. It is a sector by sector copy operation from one format to the other. It does not modify the source image and will leave it so you can continue to use it.

After all of the Windows and Linux virtual machines I have setup I decided to try a Windows p2v (Physical to Virtual) conversion. After bracing for the worst it ended up being fairly straight forward.  Steps as follows:

Virtual Machine from EC2 to KVM

If you use Amazon’s EC2 service and are thinking of migrating your virtual machines to KVM, there’s a howto tutorial available at layerboom’s website. I was contacted by layerboom with this tutorial to share and think it’s useful information you might be searching for someday. I haven’t tested this so I can’t comment on how it works but if you need to do this conversion give this procedure a try and see how it works for you.
