A while back, I found myself running out of hardware and wanting to host more sites than I currently was. In addition, I wanted to create a little bit more redundancy for some of the services I host.
At the time, I was hosting a number of services with Xen. One physical server hosted 3 or 4 virtual servers. After a certain amount of reading over different solutions, I decided to convert all my production virtual servers to Linux-vserver. I’m not advocating either solution here. I’m simply going to point out my reasons for changing and hopefully help my readers understand the issue more.
