![]() ![]() The three commercial products have licensing based on server instances rather than processor cores. From Xen to XenServerĬurrently, four different product versions are available: Free, Advanced, Enterprise, and Platinum. XenServer, the product built around the hypervisor, includes a number of services and additional software tools that help administrators build and manage anything from a simple server to a full-fledged, virtualized datacenter. Based on this extremely mature technology, Citrix launched Version 5.6 of its XenServer product family in May 2010. Xensource and its free hypervisor form the basis for what is probably the biggest rentable cloud today: the Amazon Web Service. Step 6.In the summer of 2007, Citrix invested around US$ 500 million to acquire Xensource, the developers of the free Xen hypervisor. You can also run defrags etc at this point, nice and easy whilst the VHDX is mounted. After successfully converting the existing VM to a VHDX file, I mounted it to double check the drivers directory and make sure none of the Xen* drivers were still around, there were machines that managed to have these drivers in tact which would prevent the machines booting in Hyper-V. ![]() This part was pretty critical on a couple of my VM’s. You could alternatively choose to do a vm export via XenServer CLI at this point, but I didn’t test this (Thanks Tobias Kreidl for the pointer) Be warned, you will be using a stock standard legacy NIC without XenServer tools, so your transfer speeds will suck. I chose to use Disk2Vhd from sysinternals for this part of the process, you can realistically do whatever you like tool wise, I like Disk2Vhd as its never ever failed me. This then left me with plenty of ghost devices to deal with. ![]() To resolve, I had to reinstall the latest management agent, and then uninstall. I came across some odd behaviours where even when removing the agent from add/remove programs, the driver sets would stay in play (confirmed under device management). I needed to remove these on the source VM to start with which is a commonly known requirement in the XenServer world. Uninstall XenServer Tools/Management Agent The VM’s in question are Windows Server 2016 Step 1. Below is what (after many attempts and head meets wall moments) I found to be the best way of consistently moving the workload from XenServer 7.6 to Hyper-V 2016. The tools are limited, and whilst there are some freebie options around to help, it’s the process rather than the tooling that is the challenge. Not the simplest of all tasks and disturbingly complex compared to the simplicity of moving VM’s in and out of vSphere. I recently had the unenviable task of moving a few XenServer based Virtual machines across to Hyper-V. ![]()
