Sorry ladies and gents, this post is not a how to, it is about my impressions of XenServer. With that said, on to the post.
For the last couple of weeks, I have gotten a chance to play around with a spare server at work and a copy of XenServer 6. From my experience with it so far, I really like it.
As with anything new, there is a little bit of a learning curve, but if you are familiar with virtual machines and hosts, like me, you shouldn't have a problem.
Now, unlike Hyper-V and vmWare, XenServer is open source and free, you only pay for a support contrat, if you want. I know this seems right because XenServer is owned by Citrix, but I assure you it is free. XenServer was created way back in 2003 and along the way somewhere, Citrix bought up the company.
XenServer is based on Linux, that is free.
