Xen virtual machine monitor
Why, yes, today is computer link day!
I tend to run a lot of test scenarios on the machines here at Chez Templin. My last one was setting up a 4 machine cluster for a demonstration during a presentation. (On a side note, setting up the cluster took an hour. ONE HOUR TO SET UP A 4 NODE CLUSTER. I would not have believed it if I hadn’t seen it.)
Anyway, I do, at times, run out of machines. I can’t just go out and buy new ones at the drop of a hat, and I don’t have the room (or power budget) for them anyway.
This is where virtual machines come in. I’ve done this before; when I worked at Sendmail I had a license for VMware; it’s a very nice product, and I also had a license for it when I worked at Bank of America.
VMware is very nice… if you can afford it. I cannot. Lucky for me, Linux has some built-in abilities to do multiple virtual machines on the same system, and this is taken advantage of by the Xen Virtual Machine.
Computer Laboratory – Xen virtual machine monitor – the actual project itself.
