OS Virtualization Interview

VirtualizationBuff writes "KernelTrap has a fascinating interview with Andrey Savochkin, the lead developer of the OpenVZ server virtualization project. In the interview Savochkin goes into great detail about how virtualization works, and why OpenVZ outshines the competition, comparing it to VServer, Xen and User Mode Linux. Regarding virtualization, Savochkin describes it as the next big step, 'comparable with the step between single-user and multi-user systems.' Savochkin is now focused on getting OpenVZ merged into the mainline Linux kernel."

Yep...

and if someone really want to slow their servers down by running multiples on one processer, they can just buy a bunch of $20 486's on eBay instead, and get better reliability (a h/w failure only takes down 1 server instead of many).

What's the difference between having a virus/worm/rootkit/zombie infection on a virtual server vs. a real one? You still need to rebuild/restore to recover.

I suppose it's useful for an individual who wants to run multiple OSes, and easily/quickly switch between them, but that's a very small Slashdot/geek thing (which is of course why the article appears here).
