It's a virtual world out there

I've finally been tempted to start posting blog entries. Yet Another Form Of Electronically Mediated Communication, but a good one. Most of my posts, at least, the computer-related ones, will be related to server virtualization. It's interesting times now, as a formerly niche technology has become mainstream. As somebody who happily lived for a long time in that niche (mostly in the context of mainframe VM) it's interesting to see a large number of people discover how useful virtualization can be, along with some of the pitfalls you can run into. In a world where there a virtual machines or partitioning technologies on almost every platform (VMware, Xen, Solaris Containers, LDoms, xPars, Virtual Iron and others), you can see people rediscovering issues like nested memory managers (hint: LRU no longer works the way you think). virtual timer management, and other aspects virtualized environments.
