What ever happened to UML? User Mode Linux was one of the first open-source virtualization platforms, and yet we hear nothing about it. A quick trip over to the UML website proudly talks about who’s using UML, how UML works, along with a whole suite of whitepapers.

The question is, why aren’t they getting any press. eWeek loves to print stories about how Xen is gaining ground on VMware, so why not talk about UML? In fact a quick search for “UML” only turned up results for the “Unified Modeling Language”. So next I searched for “user mode linux” and got only 8 hits. Of these, only 1 was from 2006 and even then it was only mentioned as a feature of Gentoo Linux.

So why is nobody talking about UML? Anybody have any thoughts? Maybe I can uncover something in the next few weeks.
